Articles on metal detecting and gold prospecting. Forums about metal detecting for coins, gold, relics, jewelry plus equipment reviews and more.
  • Steve Herschbach
    I have added two new sections to the website that cross link to each other. The first is a Metal Detector Database with User Reviews. Most current name brand metal detectors are listed with basic specs like price, weight, water resistance, etc. You can sort the listing by these basic specifications and you can leave your own review of each detector. Discontinued models are now being added. The new area is accessed in the menu under "Reviews"
    The second area is a revamped Downloads Area. Various manufacturer catalogs are collected there for historical reference to models, specifications and prices. More importantly, each detector in the Reviews database has it's user guide listed for download plus any other pertinent documents like sales flyers.
    Basically the Reviews area links to the Downloads area and vice versa. This is all under construction still and will be for some time as regards discontinued models. I am adding cross links and new listings almost daily. Hopefully this will allow people easier access to information and manuals now scattered across the internet. Please do your part by leaving reviews of any metal detectors you have used. Thanks!

    I recently treated myself to a metal detecting holiday to the area around Colchester, England. This was a reprise to a trip I made to the UK in 2010 in search of Celtic gold. Gold was not in the equation for that trip, but I did find the oldest coins and artifacts I have ever found.... as in 2000 years older than anything I have found before!
    Colchester has history reaching back into prehistoric times, and is generally acknowledged as the location of Britain's first city. Celtic tribes were active in the area, leaving behind many Celtic gold coins to be found by modern day detectorists. The Romans were also very active in the area, as were other invaders, leading to finds from many cultures across the centuries.
    I made a return visit to Colchester in 2018, this time relying heavily on the new Minelab Equinox metal detector as my detector of choice. I also had the opportunity to use the new Minelab Equinox 15" x 12" DD coil while on this trip. Not only did I have a very successful trip, but I got to observe other great finds made by the other detectorists in the group. All in all this was a very exciting metal detecting experience that I enjoyed thoroughly. The links below outline both my own experiences and the same trip told from the perspective of another person on the same adventure.

    XP Orx

    By Steve Herschbach, in Steve's Reviews,

    The XP metal detector company has announced a new model for late 2018 called the XP ORX. This new model appears to be a refined version of the XP manufactured Depar DPR 600. The DPR 600 was made to take advantage of the African gold rush by offering a model designed primarily as a gold prospecting detector with other uses taking a back seat. I personally think the Depar DPR 600 was used as a proving ground for the new high frequency (HF) coils while also offering an opportunity to fine tune the Gold Field program. My expectation all along is that XP would eventually release a similar model for sale outside of Africa. It looks like after almost two years that new refined version of the DPR 600 is available for purchase as the XP ORX.
    This introduction is so new that information at this time is limited - everything here is subject to change as new details emerge. For now what we know for sure is that the XP Orx will be available in two configurations. The versions are basically the same, with a wired headphone version for 700 Euro, and a wireless headphone version for 800 Euro. U.S. pricing is unknown at this time but $799 and $899 is probably in the ballpark. You can choose either the 9" round HF coil or 5" x 9.5" elliptical HF coil. There is no exact word on availability yet, but presumably we will be seeing this model available for purchase in early 2019.

    XP ORX gold prospecting metal detector
    It is possible hints about the new XP Orx can be gleaned by reading the DPR 600 User Manual. One main difference is in the User Modes. The DPR 600 and XP Orx both have four preset programs plus two user custom program slots for saved programs. The programs on the DPR 600 are designated as 1. General 2. Large Gold 3. Fine Gold 4. Iron Discriminate. The XP Orx is designed for a bit wider appeal, and so it looks like the General and Iron Disc modes have been recast as coin hunting modes. The modes on the XP Orx are 1. Gold 2. Fine Gold 3. Coin Fast 4. Coin Deep
    ORX Key features:
    HF coil technology (21 Frequencies ranging from 13 to 81kHz). Extreme sensitivity to small targets with high frequency 50kHz and 81 kHz. 4 factory programs: Gold Prospecting (x2) – Coins and Relic (x2), + 2 user. Trusted XP fast wireless technology: Coil – Remote – Headphones – MI-6. The all new “WS Audio®” compact wireless headphone receiver. Re designed ultra-light Telescopic “S” stem. The lightest machine on the market at only 770grs (remote hip mounted). Easy to operate with a user-friendly interface. Wireless connectivity to the MI-6 pinpointer + advanced remote settings. Lithium batteries, giving up to around 20 hours of detecting. Easy to charge with any certified USB charger or via computer (XP USB charger optional only) Available with a choice of HF coils – 22cm (9") Round or 24/13cm (9.5"x5") Elliptical. Compatible with the X35 coil range (22, 28, 34/28cm). Software Update (remote control via USB cable). Go terrain mobile app compatible (coming 2019). 5-year warranty – Made in France. Affordable price – Suggested maximum retail price: 699€ including taxes – 799€ including taxes with wireless headphone (WSA). Note that the upper armrest area of the rod has been redesigned and is different than the existing Deus rod assembly.

    XP ORX Controls & Settings
    ORX settings:
    99 levels of sensitivity 21 frequencies (13 kHz to 81 kHz). 99 levels of discrimination + 5 levels of IAR Discrimination in Gold programs. 20 levels of Threshold. 4 levels of Reactivity.

Target ID/ Iron probability. Pinpoint function with target zoom. Go-Terrain compatible (smartphone app coming soon). ads by Google...


    XP ORX MI-6 Compatibility
    Advanced remote settings when the ORX is paired with the MI-6 pinpointer:
    50 levels of sensitivity Audio tone from 120 Hz to 1582 Hz 2 audio modes: PITCH or PULSE 3 factory + 1 user program Recover a lost MI-6 (even when switched off) Target zoom screen Battery life indicator I don't think there is much mystery here except for how many people will opt for this new model versus the new X35 coil based Deus models. In my opinion by extending the top end frequency of the new X35 coils to 28 khz has inadvertently removed some of the demand for this higher frequency version. Small gold sensitivity gains over 30 khz are quite minimal and with the extra features the Deus offers many people may continue to prefer it as their detecting solution. A lot may boil down to the price difference between a 9" round X35 Deus package and the 9" round HF Orx package.
    No matter what I am very confident this new high frequency XP model will do very well for gold prospecting. I do not expect performance to be any different than that I observed while testing the XP Deus with elliptical HF coil on small gold.

    White's MXT Engineering Guide
    David E. Johnson, engineering consultant
    This Engineering Guide is written to provide dealers and customers greater insight into what kind of product the MXT is, from an engineering perspective. It does not attempt to provide complete information on the features and use of the MXT: for that, please consult the MXT user's manual.
    A BIT OF HISTORY
    In January 1998, White's decided to develop a true multipurpose metal detector, with the kind of sensitivity it takes to be a real gold prospecting machine, and with computerized ground tracking for ease of use. White's in-house engineering staff was tied up on the project which eventually became the DFX. Therefore, in February White's asked me if I might be interested in taking on a new protect. I had a good track record on gold machines so it seemed like a good fit. I agreed.
    A month later at a dealer seminar in Sacramento, California, Jimmy Sierra announced the project, and said if the engineer didn't deliver, the engineer would have to go into hiding in Mexico. I was sitting in the back.
    We ran into one problem after another along the way. Jimmy, good chap that he is, didn't sic the thugs on me, though there were periods he was frustrated enough that the thought must have run through his mind. Although the project took longer than we expected we got two products out of it - the GMT and the MXT.
    The first major hurdle was to get the basic circuit and software system running, with a first class ground tracking system. The system architecture was totally new, not a revision of the existing Goldmasters. In early spring of 1999 an ugly prototype was up and swinging, and Larry Sallee became involved in field-testing. By April the ground tracking system was working so well that since that time very few changes have been needed. At that point we knew we had a solid foundation, so work began on the display, discrimination and target ID features.

    During the fall of 1999, we decided to tackle the problem of desert heat head-on. A lot of gold prospecting is done in desert heat in full sun. I set up a crude but effective, thermal engineering laboratory, measuring the temperatures reached inside housings of various configurations and colors in full sun. Then began the task of finding an LCD, which would handle the heat. Because the LCD display is an important feature of the MXT, we revisited the whole issue of display. The manufacturers of LCD display had expanded their product offerings. We found a larger one, and changed the mechanical design of the MXT to accommodate it. A FSTN 0160 F was selected, (there are more to choose from nowadays, so we used a bigger one than the GMT in the MXT.)
    In early 2000, White's decided to bring out a new Goldmaster based on the work that had already been done, while development of the multipurpose unit continued. So we modified a prototype to work with the Goldmaster search coil at about 50 kHz, and you know the rest of that story - the GMT "tracking Goldmaster" was introduced in early spring of 2001.

    As work continued on what eventually came to be called the "MXT", we spent a lot of time on the discrimination and target ID system. There are many different ways to do discrimination and ID, each with its own advantages and disadvantages, which aren't always known until you've had the thing in the field being tested for a while. A lot of work got thrown out as we found deficiencies in what had already been done, and discovered ways to improve things. As the project got closer to production, more people became involved with it, and offered their own ideas to improve it. The reason the MXT is as good as it is, is because of that long process of field-testing and revisions.
    While the MXT was still under development, the DFX was introduced. The MXT design was then revised to run at about 14 kHz in order to take advantage of the DFX loops.
    When it was finally time to call it "good" in June 2002, the MXT went into production quickly and smoothly.
    CIRCUIT DESIGN
    The circuitry of the MXT is almost identical to the GMT, which has already been on the market for a year and a half and has proven to be rock-solid.
    The GMT's circuitry broke a lot of new ground. It uses a reactive impedance transformation network to boost transmitter voltage for higher sensitivity. It uses an active transmitter regulator to keep transmitter voltage constant even when the search coil is moved over black sand that would blow an unregulated machine off the air. The differentiator-filter circuits usually found in metal detectors are eliminated. Those functions are now done in software, which is made possible by the use of a high-precision 16-bit A/D converter used in a way that makes it equivalent to 17 1/2 bits. All the controls are digitized, their function actually performed via software rather than in circuitry. The audio system is temperature compensated in software to eliminate threshold drift.
    For the MXT, we chose an operating frequency of 13.889 kHz. This is high enough to give good sensitivity to gold, low enough to give good target ID on typical coin, trash, and relic targets, electrically compatible with search coils derived from the DFX and halfway in between power line harmonics to minimize electrical interference.
    SOFTWARE
    The MXT uses a Microchip PIC 16C76 micro controller, chosen for its low power consumption and its set of features, which was a good match for this application. The software that runs in this chip is based on that in the GMT, but almost all of it is new or has major revisions, except the device drivers and the ground tracking system. Much of the new software is for target ID and discrimination, features that were not present in the GMT. Even the iron probability and VSAT systems in the MXT are new, despite their apparent similarity to the GMT.
    The MXT/GMT does as much of the signal processing as possible in software rather than in circuitry, using what we call "low-speed DSP architecture". The demodulated signals are digitized, and processed and analyzed in software. Control positions are also digitized and made part of the data in software. The desired audio signal is computed, and then converted back to voltage using a 12-bit D/A converter. The circuit board communicates with the LCD and trigger switch in the "pod" via a custom-designed serial link.
    In the MXT the filters, differentiators, and sample-and-hold functions are performed in software, not in circuitry. This eliminates the problems of channel mismatch and drift, which are often encountered in such circuits.
    The discrimination system is a second derivative ("two-filter'') design for quick response over a broad range of sweep speeds. The analysis system for determining what kind of target is present has special features which reduce interference from ground minerals, and which automatically scale target ID confidence according to the mineralization level.
    GROUND TRACKING SYSTEM
    The ground tracking system comprises two subsystems: a ground analysis engine, and a ground balancing system. The ground analysis engine continuously monitors incoming signals to determine whether the signals probably represent ground, or may be something else such as metal targets or electrical interference.

    Signals, which seem to be ground only, are put into a data analysis subsystem, which analyzes the data for a number of variables. Then it can be determined what the balance point of the ground matrix is and how fast that balance point is changing. It'd be nice to describe all this in detail but we'd rather not teach our competitors how to do it.
    The ground balance system does the actual balancing of the signals, doing in software somewhat the same job as a ground balance knob does on a manually balanced machine. When the TRAC toggle is in the "ground" or "salt" positions, the ground balancing system follows the output of the ground analysis engine. When the toggle is in the center "lock" position, the ground balance subsystem stops following the output of the ground analysis engine, which is still chugging away in the background continuing to gather ground data.
    The ground analysis engine can do a good job of telling the difference between ground matrix and anomalies such as hot rocks and metal targets. In order to tell the difference, it has to see matrix by itself during at least part of the sweep. When you're not in "lock", keep your sweeps broad, and don't loiter over the top of a target when checking it out. Otherwise the analysis engine may lose the ground matrix and start tracking into the target. However, if the target is strong enough to register on the VDI readout, the target ID system will tell the analysis engine to halt, allowing you to check the target without tracking into it. In all three programs, pulling the trigger to pinpoint a target also tells the ground analysis engine to halt. Some users will hunt with the tracking toggle in "lock", occasionally updating the ground balance by flipping into "ground" or "salt" momentarily when they start hearing too much ground noise.
    The resolution of the ground balancing system is 1 part in 4,000, and most of that resolution is concentrated in the range where high mineralization occurs. Therefore, the individual resolution steps are below audibility under all conditions.
    THE VSAT SYSTEM
    The VSAT system on the MXT is similar in a general way to the one on the GMT. The VSAT function is done entirely in software. Up to about 2/3 rotation, the SAT is of the conventional (first derivative or auto tune) kind, giving a "zip" sound on a nugget and a "boing" sound on a negative hot rock (cold rock).

    As you approach maximum rotation, the MXT goes into "HyperSAT". HyperSAT is a completely different type of SAT system with different sounds and target responses. The background threshold sound is a little rattier, but nuggets are crisper, the ground is quieter, and negative hot rocks vanish when you slow down your sweep. For all but the most experienced users whose ears are calibrated to hear every little nuance of a regular SAT signal, HyperSAT gives more effective depth in bad ground than normal SAT.
    THE DISCRIMINATION CONTROL
    The discrimination control does pretty much what you'd expect. Unlike some discriminators, when the control is at zero, there is no discrimination at all - i.e., "true zero discrimination" - and all targets will be detected. Below about 2, the discrimination is based on a combination of both signal phase, and signal strength relative to the strength of ground mineralization. This feature allows the user to get good rejection of shallow iron with minimal loss of deeper targets.
    THE GAIN CONTROL
    The gain control knob controls two things at once: the preamp circuit gain, and the software gain. The following is a simplified explanation which is not technically correct in all its details, but will serve to give a general picture how the gain control works.
    As you advance the gain control from 1 to 10, the preamp circuit gain steps through five levels of gain: xl, x2, x4, x8, and x16. On most machines (depending on minor variations in search coil alignment) you can hear a momentary blip as the machine switches from one gain level to the next. The recommended preset (marked by the triangle) corresponds to a preamp gain of x8.
    In mild ground conditions where there is no electrical interference, you may want to advance the gain control into the crosshatched region. In this region, the signal data in software is multiplied by successively larger numbers, increasing the loudness of the signals. It is somewhat similar to the "audio boost" function found on some other models of metal detectors. It's particularly useful if you're using the speaker rather than headphones and there's a lot of noise from traffic or wind, or if you're demoing the machine to someone else.
    BASIC SENSITIVITY PERFORMANCE
    Since this is a multiple-purpose machine, a U.S. Nickel coin is the most appropriate standard test target. With the gain cranked up, and in the absence of electrical interference, a nickel will typically "air test" beyond a foot using the standard 95O search coil. Your actual "air test" distance will depend on your hearing, the sweep speed, what search coil is used, how much electrical interference is present, and how you have the controls set.

    In comparison to other machines in this price range, the MXT is extremely hot on low-conductivity items. On gold, it's right in there with the more popular gold machines, being especially hot on the larger, deeper nuggets. It will compete with all comers on low-conductivity , relics and on nickels. On high conductivity coins such as quarters and silver dollars, it is still an excellent performing machine, but there are several other products in the same league for sensitivity.
    GROUND TRACKING PERFORMANCE
    The ground tracking system is nearly identical to that in the GMT, which is widely regarded as one of the best tracking systems on the market. Compared to most other trackers, the MXT has superior resolution, tracks faster, "jumps" into new ground more quickly, has greater resistance to tracking into targets, and tracks over a wider range of soil conditions. The MXT allows tracking to be inhibited if desired.

    DISCRIMINATION PERFORMANCE
    All discriminator designs are compromises. Here's how the discriminator in the MXT stacks up against other machines.
    AIR TEST "DEPTH": generally well beyond 10 inches, because of high sensitivity, with effective discrimination to within 0-3 inches of the basic air sensitivity of the target. Most discriminators will discriminate in air to within 0-3 inches of the target air depth on most targets, but most don't have the sensitivity of the MXT.
    QUICKNESS & TARGET SEPARATION: among the best, because of medium-speed second derivative ("two-filters") design. Initial field reports indicate that the MXT's mixed-mode tone system gives indication of adjacent ferrous/nonferrous targets, superior to that obtainable through discrimination.
    IRON REJECTION: Because of its high sensitivity and a slight preference in the software for not losing questionable targets, it'll be a little chattier than some less sensitive machines. Reducing sensitivity by cutting back on gain, or by reducing the threshold control setting to minimum, will help quiet it down when necessary.

    DEPTH IN MINERALIZED GROUND: Although the MXT is a two-filter system, it incorporates special techniques which reduce ground interference and which reduce the "chopping & popping" which plague most other two-filter machines. This, together with its high basic sensitivity, makes it an excellent machine from the standpoint of discrimination depth.
    FAST SWEEPING: Many discriminators tend to lose good target signals, even shallow ones, when quickly sweeping the search coil. The MXT is tolerant of moderate search coil sweeps, that is to say good at both faster and slower search coil paces.
    SUMMARIZING: The MXT has the responsiveness and sensitivity of a first-rate 2 filter machine, combined with the discrimination accuracy of a first-rate 4-filter machine.
    TARGET I.D., ETC.
    With its small medium and large blocks on the target ID screen, the ID system in the MXT bears a superficial resemblance to the "Signagraph" of the Spectrum XLT.

    It should be realized that the traditional White's Signagraph system is typically (optionally) set to accumulate data over multiple passes over a target, and displays the accumulated average. The MXT displays fresh data on each pass and scales the size of the block according to how strong the signal was relative to the ground conditions on that specific pass over the target.
    The visual ID system on the MXT is fast, easy to read, generally more accurate than the discriminator, and gives a visual indication (via block size) of how reliable the identification is. It is going to change the minds of many beeper enthusiasts who previously thought visual ID to be of little practical use outside typical coin shooting.
    CASCADE
    THE CASCADE OF EFFECTS OF GROUND BALANCE SETTING: In order to know what the ground balance setting is; flip momentarily to the gold program if you were in another mode.

    Electronic ferrite material and most "negative hot rocks" (cold rocks) will usually read in the 75-88 range. Most soils will read somewhat lower. Readings will almost never go below 25 except in salt or moist alkali soils. When readings indicate smaller numbers than 50 you may notice some reduction in sensitivity. Below 35, some rusty iron may give unpredictable responses. Below 25, iron objects may give unpredictable responses and/or may disappear entirely and the sound on nonferrous objects may become slightly more abrupt.
    MANY THANKS
    To Kenneth White and Alan Holcombe for having sufficient confidence in me to put food on my table through the good times and the rough times on this project. To Jimmy Sierra for having the patience to argue with me about all the stuff that needed arguing about, for being so passionate about the need for this product, and for being willing to compromise when that's what it took to keep the project moving. To Larry and Sue Sallee, for their personal hospitality and for field testing prototypes. To Keith Zorger, Randy Smith, Mike Brighty who field-tested and helped develop the MXT. To Bob Canaday, for being such a competent technical/engineering liaison, doing a lot of not glorious but necessary work well and managing the project during its sometimes difficult phases. To Rick Maulding, for overseeing the project, for technical contributions to the discriminator and to the salt system, and for committing White's engineering department's finest minds to engineering review during the "slow SAT isn't hot enough" crisis, which led to a major system revision that made the whole machine better. To John Earle and Dan Geyer, for diligently hacking away at problems until they became non-problems. To Steve Howard and Pam Godell of White's. There were other people involved in this project whose contact was primarily or exclusively with White's and not with me. The risk of printing credits is that one may inadvertently omit a name that belongs there; so, if I missed someone whose name belongs on this list, I'm sorry, it was an unintentional oversight. - D.E.J.

    The Chisana area of Alaska was the site of the last major gold rush in Alaska in 1913. As a young man researching areas to look for gold I found a reference to this remote location in the Wrangell St. Elias Mountains. It is accessible only by air and for short periods of time each year. I started visiting this area in the early 1970's and then off and on again over the decades that followed.
    The area is high above treeline and frozen for most of the year. It was mined with simple shovel into sluice box type operations along the creeks followed up by hydraulic mining on bench deposits. The remote location, lack of water, short season, and generally small area of the gold deposits meant this district never saw anything more complex than hydraulic mining operations. In later year operations have been confined to smaller scale hand operations plus gold dredging and metal detecting.
    I told a couple stories about this area as part of my Steve's Mining Journal but kept fairly low key about the location. This was mostly because the claim owners were not looking for publicity. However, the mine owners decided to sell a couple of their claims. They had to advertise them to sell them. That in turn gave me the excuse to finally tell more about my visits to the place over the years, and to share the many photos I have of this rather unique part of Alaska.
    I am telling the tale as part of an on-going episodic thread on the Detector Prospector Forum - The Chisana Story - check it out!

    The White's Goldmaster 24K has been announced and has just started shipping to customers. The Goldmaster 24K is an alternative to the White's GMT updated for the 21st century, with advanced ground tracking technology and increased power. XGB technology is a patent-pending automatic ground balance system. It is purpose-built for operating a high-frequency VLF gold nugget detector in the worst ground conditions. Traditional VLF detectors struggle to balance rapidly changing ground mineralization. Historically this has been where Pulse Induction machines fared much better.
    With XGB technology, the Goldmaster 24k is able to track small changes in soil composition as well as longer-term shifts in both ground phase and strength. This allows it to operate in ground that traditional VLFs struggle in. Users have extended control over the range of XGB in the Goldmaster’s All-Metal mode. Simply enable Iron Cancel to expand the ground filter in moderate soils. In very challenging soil conditions, hold the Iron Cancel button and select the 2-bar setting for maximum performance in variable ground.
    New 9/12/18 - Detailed Review Of White's New Goldmaster 24K

    White's Goldmaster 24K metal detector - new for 2018
    The new White's Goldmaster 24K also features a full backlit LCD target id screen and control suite. The potential target id is displayed on the screen whenever possible - the higher the number, the better the chance of a non-ferrous target. There is dual tone capability that reports a low tone for ferrous objects, and a high tone for all non-ferrous targets.
    White's Goldmaster 24K Features
    SENSITIVITY - Set the sensitivity at a level that does not result in false signals from the ground. Very strong ground may result in the symbol on screen and a loud sound - this means the sensitivity is too high. GROUND BALANCE - With the default setting, the detector will use XGB to automatically ground balance. Tap to lock the ground balance to the current setting. Tapping when the ground balance is locked will update the current ground setting to what is under the coil. GROUND SCAN - Hold to put the detector into Ground Scan mode. The top bar displays the ground strength and the two digit numbers display the ground type (phase). Useful for tracing paystreaks. IRON CANCEL - Tap to silence hot rocks, trash and mineral changes in both audio modes. Hold to select the Iron Cancel setting (1 bar is default). Note that this setting may decrease the detector’s sensitivity to very small gold, but is necessary in difficult ground conditions. VOLUME and THRESHOLD - Tap to adjust the volume with the up and down buttons. Hold to adjust the threshold with the up and down buttons (“th” displays on screen). Set these to a comfortable level for your hearing and preference. AUDIO MODE - With the displayed on screen, the detector is in “BEEP” audio mode (high tone = good target, low tone = bad target). The default setting (without on screen) is a traditional All-Metal audio mode with greater sensitivity to small targets. SAT - SAT can smooth out ground inconsistencies. Hold to adjust it (“Sa” displays on screen, 2 is the default setting). PINPOINT - Hold for non-motion pinpoint mode. In difficult ground this mode may be affected by mineralization. BACKLIGHT - Tap to enable the backlight (this reduces battery life). FREQUENCY SHIFT - Hold when turning the detector on to shift frequency (useful when there is EMI). Power off to save the selection. FACTORY RESET - Hold when turning the detector on to perform a factory reset. Not only does the new White's Goldmaster 24K features a new ground tracking system, but the gain has been boosted with an increase of voltage to the coil. From the Advanced Guide (link below):
    "When our engineers set out to build the GM24k, the goal was simple: improve the user’s chance to find gold without hurting their wallets. The obvious way to achieve this goal is increased sensitivity. The GM24k features a 54% increase in coil voltage over the GMT. You will see this in increased sensitivity to small nuggets. While testing this machine in Brazil, this was shown in a tiny, 0.4 grain crystalline nugget we found encased in quartz. In some cases this much power can be counter-productive if the ground is very challenging, so use it with caution! Even at lower gain settings the GM24k is an extremely “hot” machine on small gold and specimen nuggets."
    The new White's Goldmaster 24K comes with both rechargeable batteries and a holder for AA batteries. The GMK comes standard with the 6" x 10" DD search coil. Currently the is one accessory coil available, a 6" round concentric coil. Both a 14" x 8" DD and 6" x 4" DD coil are possible in the future but have yet to be offered for sale as of March 2019.

    GOLDMASTER 24K WHITE'S PAPER
    XGB - A New Way To Ground Balance
    The biggest challenge we face as electronic prospectors is highly mineralized ground. Simply increasing the gain on the current VLF platforms might help prospectors in very mild ground conditions, but what about more difficult areas with concentrations of black sand, maghemite, serpentine, or alkali salts?
    On a trip to Brazil we witnessed a combination of these conditions, with soil that ranged from red to black to purple, and exhibited a combination of ferrous and alkali properties within a 4 ft square section. We saw first-hand VLFs from each manufacturer fail to balance out the combination of minerals. Even the top-of-the-line pulse induction machines struggled in this area - machines which cost the garimpeiros (the local term for gold miners) several years’ wages.
    Our goal was simple: a nice even threshold in challenging ground conditions without giving up sensitivity. The theory is that the main battle most electronic prospectors fight is being able to discern a potential gold signal from ground noise. A smooth threshold would allow users to use more gain and increase their odds of finding small gold where it likes to hide - in mineralized ground.
    The issue with other VLF detectors on the market is that they were tracking a single ground balance point. When the ground type changes quickly, the machine gives off a false signal. For a user the result is ear fatigue, frustration, and less positive signals dug. One easy way to mask variable ground is implementing an auto-gain feature  that automatically numbs the detector. This does not solve the issue, only hides it.
    The Goldmaster 24k’s XGB is a new automatic ground tracking system that works by tracking multiple ground points simultaneously and quickly. Where other VLF’s track one ground balance point, the Goldmaster 24k tracks several, and can determine an optimal “ground window” based on ground history and strength. This is very useful in rapidly changing ground conditions, where other VLF machines may struggle to track the mineralization changes. Combine this with the speed at which the Goldmaster 24k is able to grab ground samples, and you have a superior ground balance system for a prospector’s VLF.

    XGB Ground Balance versus legacy methods
    With any automatic process, there are some concessions. Take vehicles for example - manual gearboxes are still preferred by car enthusiasts. That’s why we felt strongly about including a TracLock® ground option. When used with the Ground Grab, a locked ground balance setting allows users to set the ground balance in an area and lock it until they need  to re-ground balance. For users after the tiniest bits of gold, this option allows for the maximum sensitivity to small signals.
    One technique we observed from field testers was allowing the XGB to automatically track, and  then  after getting a solid hit or finding a patch, locking the ground balance for target location and retrieval. For  many users this combination will be the best of both worlds - the strength of XGB, but only when you need or want it.
     
    The net result of an overhauled automatic ground balance system is a VLF gold nugget detector that  can  be   used   in wider variety of ground conditions with a nice stable threshold. Operating a machine with a smooth threshold allows for a user’s ears to tune into those slight variations that just might be the next nugget. Our goal is that our customers are able to have success with the Goldmaster 24k in areas that other VLF’s struggle, and at a price that allows more people to get a taste of electronic prospecting.

    Benchtesting Rocks & Minerals with an F75 Metal Detector
    Introduction
    From the earliest time when we were aware of our surroundings, most of us looked for pretty rocks. We wondered what interesting or valuable minerals might possibly comprise them. Now as adult hobbyists, I doubt if any of us hasn’t benchtested an interesting rock from curiosity, and wondered what actually produced the signal. 
    Although a sensitive benchtest usually has little in common with how marginally conductive rocks and minerals respond to metal detectors in the field due to ground effects, we can learn and become familiar with how rocks and minerals in our respective areas respond to metal detectors in a benchtest. A sensitive metal detector’s electromagnetic field penetrates rocks, usually generating either a positive or a negative signal in response to whatever material is in the rock. We can sometimes determine whether such signals should be investigated further, or whether worthless iron minerals produced them. 
    I’d generally describe my benchtest results as worthwhile and informative, but that notwithstanding, I look forward to doing a benchtest because I think it is an intriguing study on its own merit. That said, how do you conduct a benchtest? I’ll describe my methods and hopefully we’ll see what you think about it.

    Benchtest Requirements and Techniques
    Benchtesting ideally requires a visually displayed, fully calibrated, manually adjustable ground balance that covers the entire (soil) mineral range from salt to ferrite. As a minimum, the detector should feature a threshold-based true motion all-metal mode, and preferably an additional true non-motion all-metal mode for significantly improved sensitivity to borderline samples. Visual displays in either of the true all-metal modes are essential for target ID, Fe3O4 magnetic susceptibility and GB readouts. 
    I prefer a small (concentric) coil to promote detector stability and improve sensitivity to the rock sample, to ensure uniform sample exposure to the coil, and to minimize EMI (electromagnetic interference) especially if benchtesting at home. Elevate the sensitivity control as high as possible while maintaining reasonable detector stability such that you can clearly hear changes to the threshold.
    To check for a target ID, move the sample back and forth across the coil at a distance that produces the best signal but does not overload the coil. To determine ground balance and Fe3O4 readouts, advance the sample toward the coil, back and forth to within an inch or two (depending on sample size and signal strength) of the coil’s electrical sweetspot. Ensure your hand does not come within detection range of the coil to avoid creating false signals. If you extend your fingers to hold the sample, this is not an issue when testing larger samples. If necessary use a plastic or wood food holder that can firmly grasp small samples.

    Benchtests should be conducted utilizing a minimum of two widely diverse GB control adjustments. Initially I prefer the same GB control adjustment that is typically required to keep my detector ground-balanced to the substrates in my prospecting areas. It’s a personal preference that works for me. That particular GB control point (F75 / GB86) is more likely to improve any rock or mineral sample’s signal strength compared to using a more reduced (more conductive) GB compensation point.
    The next step is to use a dramatically reduced GB control adjustment (F75 / GB45) as suggested by Fisher Research Engineering. This setting ensures that (obviously weathered) oxidized samples do not generate a positive signal from any type of non-conductive iron mineral inclusions, particularly maghemite mineralization that may be present within such rocks. It follows that this second benchtest will, if anything, slightly subtract from the sample signal strength, particularly with low grade and otherwise marginally conductive samples, compared to the first step of the benchtest at GB86. 
    As a general rule, I do not recommend the F75 / GB45 compensation point for benchtesting (non-oxidized) mafic samples that are dominated by constituents such as common magnetite or other black minerals that normally support highly (non-conductive) elevated GB readouts. Such samples can produce strong negative threshold responses at the reduced GB compensation point. It will be difficult or impossible for the signal from a marginally conductive substance to successfully compete with those negative threshold signals. For non-oxidized samples Fisher Research Engineering suggests using F75 / GB65 rather than the F75 / GB45 compensation point, since obvious iron mineral oxidation should visually be absent from such samples.
    With the above discussion in mind, extremely fine-grained, unweathered magnetite that occurs in pyroclastic material (for example volcanic ash) can drop into the GB45 range, but it is extremely rare. Unweathered volcanics do frequently drop into the GB70's due to submicron magnetite, but the recommended F75 / GB65 compensation point will eliminate those positive signals. 

    The arsenopyrite sample depicted above is a good example of a commonplace mineral that we encounter in the silverfields of northeastern Ontario. Generally field examples could be described as marginally conductive and many are low-grade. A good many react with only a mild positive signal, and sometimes not at all to a benchtest depending on which GB compensation point is used. 
    The high-grade, solidly structured sample above produces a strong positive signal in either zero discrimination or true motion all-metal mode with the ground balance control adjusted to the GB compensation point required for our moderately high mineralized soils. As noted, that’s approximately F75 / GB86, although in the field, of course, it varies somewhat depending on location and coil type / size employed. 
    The response is not as strong as a similar size and shape metalliferous sample would produce, but it does generate a surprisingly strong benchtest signal that would be readily detectable in the field. Even with the GB control dramatically reduced to more conductive values (F75 / GB45), to ensure that any positive signals produced by non-conductive iron mineral inclusions should now only produce a negative threshold signal, it is no surprise that this (non-oxidized) specimen continues to generate a strong signal. 

    For those readers unfamiliar with detector responses to such minerals, the same general response scenario described above with arsenopyrite applies to other marginally conductive minerals such as galena, pyrrhotite and to a lesser extent even iron pyrites. Ordinary iron pyrites is generally innocuous, but maghemitized pyrite, pyrrhotite, and the copper sulfide ores, particularly bornite and chalcocite, can be a real nuisance in the field due to magnetic susceptibility, magnetic viscosity, and / or electrical conductivity, just depending on what minerals are involved. 
    Such variable responses from arsenopyrite and many other mineral and metalliferous examples clearly infer that signal strength and potential target ID depends on a sample’s physical and chemical characteristics, including the quantity of material within a given rock. These factors include structure, size, shape, purity (overall grade), and magnetic susceptible strength of iron mineral inclusions. Moreover, the VLF detector’s sensitivity, the GB compensation points employed, the coil type and size, and the sample profile presented to the coil further influence benchtest target signal strength and / or potential target ID readouts. 
    Incidentally, neither of my PI units will respond to the arsenopyrite sample depicted above, even with a TDI Pro equipped with a small round 5” mono coil, the GB control turned off, and a 10 usec pulse delay to deliver its most sensitive detection capability. That result is typical of most, but certainly not all sulfides and arsenides that occur in my areas. Higher grade and solidly structured pyrrhotite, an unwelcome nuisance iron sulfide, and collectible niccolite, a nickel arsenide, are commonplace mineral occurrences here that do respond strongly to PI units, although their respective VLF target ID ranges are quite different. 
    As a related but slight diversion, the photo below depicts a handsome example of the widely occurring mineral sphalerite. It forms in both sedimentary beds, and in low temperature ore veins. It is interesting to collectors because it possesses a dodecahedral cleavage which means that it breaks smoothly in twelve directions, and it is usually triboluminescent, meaning that it gives off a flash of light when struck sharply. Like many desirable minerals lurking in prospecting country, unfortunately sphalerite doesn’t react to metal detectors. 

    A Final Word
    The foregoing is intended to illustrate that sensitive metal detectors can be utilized as a supplementary tool to assist with evaluating rocks and minerals. There is no question that the benchtest has serious limitations, particularly if trying to distinguish positive signals produced by some types of iron mineral inclusions from weak conductive signals. 
    That notwithstanding, a positive signal that persists below the F75 / GB45 compensation point cannot be confused with iron mineral negative threshold signals produced at that same compensation point. Therefore a positive signal merits further investigation. Such signals are almost certain to be generated by a marginally conductive mineral or a metalliferous substance. 
    On the more interpretive side of a benchtest, we need to point out that weak positive signals from lower-grade samples of minerals such as arsenopyrite, galena, pyrrhotite, chalcopyrite, and doubtless a few others, may disappear well before the GB control is reduced to the F75 / GB45 compensation point. We learn early that benchtests are frequently equivocal and require interpretation based on any further evidence that might support the benchtest result. Look for iron oxidation in addition to structural or other physical evidence as described above that could explain why a sample reacts as it does to a metal detector.

    Introducing the Makro Gold Kruzer metal detector, new for 2018. The Makro Gold Kruzer is available now from select dealers. The 61 kHz Gold Kruzer breaks new ground by being the lightest weight highest frequency waterproof detector on the market. Be sure and read the detailed review by Steve Herschbach at the bottom of this page below the specifications list.
    The Makro Gold Kruzer comes standard with a 10" x 5.5" concentric coil plus a 4" x 7.5" DD coil and has one optional coil available at launch. The Gold Kruzer has proprietary 2.4 Ghz wireless headphones included. The big announcement of note however is the very high 61 kHz operating frequency, making this one of the hottest machines available on tiny non-ferrous targets, and the only one waterproof to over 5 meters (16.4 feet).
    There are already a number of detectors on the market operating in the over 40 kHz region and the basics of this high frequency detection have been covered well for at least twenty years. In other words, if all a person wants is a detector running in a high frequency threshold based all metal mode, there are quite a few options to choose from.
    What makes the Gold Kruzer interesting is that as far as I can recall, nobody has made a detector before where the primary design intent is jewelry detecting. More to the point with the Gold Kruzer - detecting for micro jewelry. Micro jewelry has no exact definition but basically just means very small, hard to detect jewelry. Things like thin gold chains, or single post earrings. Most standard coin type detectors are weak on these sorts of small targets, if they can even detect them at all. Up until now people had to choose between coin detectors that have the features but are weak on micro jewelry targets, or use dedicated gold prospecting detectors hot on small targets, but very limited in features. What that usually means is little or no discrimination features.

    Makro Gold Kruzer for detecting jewelry, gold nuggets, and more
    Makro has gained attention as a company that listens to its customers. The new Gold Kruzer model is the perfect example of that, creating a unique machine based almost solely on feedback provided by customers in the last couple years. The Micro Mode on the new Gold Kruzer is a direct nod to those who want a detector for hunting micro jewelry and possibly even for gold prospecting, but who do not wish to give up the features available on most detectors today. In fact, Makro goes a step beyond, with the Gold Kruzer sporting features not included on many detectors today. These would include being waterproof to ten feet of more (16.4 feet with the Gold Kruzer), built in wireless headphone capability, and the ability to receive firmware updates via the internet.
    The result is a new detector with a unique feature set. There is literally no other detector made right now operating over 40 kHz that is fully submersible. Built in wireless and internet updates are frosting on the cake.

    Detailed Review Of Makro Gold Kruzer by Steve Herschbach
    I was asked to review a new gold detector in the fall of 2014 from a company I had never heard of before then – the FORS Gold by the Nokta company based in Istanbul, Turkey. I was pleasantly surprised to find the Nokta FORS Gold to be a very capable 15 kHz VLF detector that could serve well not just for nugget detecting, but almost any detecting tasks.
    The FORS Gold did have some odd design quirks, like the use of mechanical rocker switches instead of touch pads. I listed a few of these things, expecting that would just be the way it is. I was almost shocked when within a short period of time Nokta fixed or changed every item I had mentioned in my review as possibly needing improvement. This was unusual as normally once a machine has gone into production manufacturers are extremely resistant to design changes, especially changes in the physical design. It was a sign of what people have now found to be fact – that this company is serious about listening to their customers as a prime driver for product improvement.

    New Makro Gold Kruzer
    It was revealed that Nokta had a sister company called Makro, and the two officially combined forces shortly after I made my review. In other words, both Nokta and Makro now share the same ownership and management, but continue to be marketed separately under the two brand names. The detector models that each sell are unique, but there is an obvious sharing of the underlying technology between some models that the two brands sell.
    I had commented at the time that I would prefer a more standard configuration for a LCD based detector rather than the non-standard configuration as presented by the FORS Gold. By the fall of 2015 I was using the new Makro Gold Racer, which incorporated many ideas I had lobbied for over the years with detector manufacturers. I had been trying for some time to get somebody to create a metal detector that ran at nugget detecting type frequencies over 30 kHz but with a full target id system. It seems strange now but at that time nobody made such a detector.
    The Makro Gold Racer was quite unique in 2015 by offering a detector running at 56 kHz that also offered a full range LCD based target id system and dual tone based audio discrimination modes. This made it a detector useful not just for nugget detecting, but low conductor hunting in general for relics and jewelry. It is even a halfway decent coin detector for regular park type scenarios. The versatility and well thought out control scheme scored points with me, and I still have the Makro Gold Racer even after selling most of my other detectors.
    It seems that the moment the Makro Gold Racer hit the streets, that everyone else was working on similar ideas, as other detectors running over 30 kHz but with a full feature set started to appear on the market. High frequency detecting is suddenly in vogue for more than just gold nugget detecting.
    The one thing obvious now about the Makro / Nokta partnership is that they never sit still, but continue to work on and release new models at a pace that puts all the other manufacturers to shame. The companies are also big believers in seeking public feedback and then implementing the suggestions to create better products for their customers. This is readily apparent in the progression I have personally witnessed in going from that original Nokta FORS Gold to the new 61 kHz Makro Gold Kruzer just now hitting the market. In less than four years the company has gone from “catching up” to meeting or surpassing detectors made by other companies.
    ads by Amazon...
    The Makro Gold Kruzer has a full suite of functions, is fully waterproof, incorporates built in wireless headphone capability, and can be firmware updated over the internet. That short feature list alone puts the Makro Gold Racer in a very select group of detectors offering those same 21st century “basic features” that were lacking in almost all detectors made in the last century.
    The Makro Gold Kruzer obviously builds on the Gold Racer feature set with the following key differences. The Gold Racer runs at 56 kHz and the Gold Kruzer at 61 kHz, one of the highest frequencies available in consumer metal detectors. This continues the focus on detecting small low conductor targets. The Gold Kruzer is waterproof to 5 meters (16.4 feet) whereas the Gold Racer is not waterproof at all. Finally, the Gold Kruzer adds a three tone hunt mode, taking things up another step from the dual tone modes available on the Gold Racer.
    Now let’s look at the Makro Gold Kruzer in detail. Makro switched things up in that the Gold Kruzer comes with two coils, a 5.5” x 10” concentric coil, and a 4” x 7.5” DD coil; both include scuff covers. The 5.5” x 10” concentric coil, which was an option offered for the Gold Racer, has been redesigned and cut from 1” thick to ¾” thick and the weight reduced to 384 grams (13.5 oz). The coil is hollow and therefore slightly buoyant, so the 25% reduction in thickness is quite welcome in reducing that buoyancy to where it is basically unnoticeable underwater.
    The little 4” x 7.5” DD coil is a solid epoxy filled coil which works extremely well in smaller coils where epoxy filling does not result in too much weight. The small DD coil weighs 368 grams or 13.0 oz. There is one accessory coil available at this time, a 5” x 9.5” epoxy filled DD. This coil weighs 14.3 oz or 404 grams. It should be noted that because of the frequency change and with the Gold Kruzer using waterproof connectors, that Makro Gold Racer coils will not work on the Gold Kruzer.
    Makro has also learned lessons as regards coil ear durability. The coil ears on the Gold Kruzer are about twice the mass of those on my older Makro Gold Racer. Taller, wider, and thicker – these extra beefy coil ears should all but eliminate breakage issues.

    4” x 7.5” DD coil showing beefed up ears
    The Makro Gold Kruzer employs a fairly standard “detector pod on an S rod” design forgoing the underarm battery box used on the Gold Racer. This confers a large advantage when it comes to waterproofing the detector in that only the pod has to be sealed. The change from AA batteries to a built in sealed LiPO rechargeable battery also aids in eliminating battery doors, which are always at risk of leaking.
    The three piece S rod itself is quite stout with no flex or wiggle. The cross hatch carbon fiber lower rod is not only strong, but lends an air of high tech quality to the look of the detector. The Gold Kruzer does not have the separate underarm battery compartment and in handle vibration mechanism featured on the Makro Gold Racer. This means the pod is totally self contained and can be removed from the handle assembly. This in turn allows for other rod options and the ability to break the detector completely down fitting in a small backpack or carry on bag.
    When the stout rod is combined with the beefed up coil construction you have a design that should survive those spills a person can take when working in the surf and there the detector ends up acting like a walking stick for support.
    It has been interesting to watch the company experiment with different handle designs. It is a thankless task because you never can please everyone. For me at least the handle / rod may be the best yet from Makro, with a molded hard rubber grip that will serve very well for a detector that may see underwater use. I personally found the Nokta Impact handle to be large for my hands and the smaller Gold Kruzer handle near perfect. Others may feel just the opposite so there you go.
    The arm cuff is a little different. It is narrower than some – good for me but maybe not so much for somebody with huge forearms. The adjustment is non-standard, with the arm cup sliding up and down the upper rod over a set of threaded holes. A small screw inserted into the top of the armrest and into one of these threaded holes secures the armrest in place.

    Kruzer upper rod showing cuff adjust holes and hand grip (control box removed)
    A unique feature on the Gold Kruzer is an optional external AA battery pack that can provide extra operating time in the field should the internal rechargeable battery go dead. The pack is designed to be held into the bottom of the detector armrest / stand by a separate plastic cover bracket that is held in place with two screws. I found the holes these screws go into will fill with sand if this bracket is left off, so I advise installing the bracket even if the external battery pack is not in use. The external battery pack with bracket is an option and so dummy screws or plugs should be installed to keep the screw holes clean and free of debris by those who down not have the bracket.
    I don’t think most people will ever need the external battery pack as long as the detector is regularly charged after use. It is a very nice touch however, especially for off grid use, as all you need is the external AA battery pack and a box of AA batteries to off grid for as long as the batteries will last. Some people may want the optional battery pack for travel into the field just in case the battery runs short on power in the middle of a hunt.
    The port where you attach the external battery pack also acts as a port to attach a USB style charger cable. The detector is charged using this cable by employing the included USB wall charger. You may also use most USB charging adapters and newer computer USB ports.
    The USB cable also allows the Makro Gold Kruzer to be attached to a computer so that updates can be made in case any bugs are found in the future. This update feature is very nice insurance that should be standard on all new detectors.
    Another item that should be standard on all new detectors is built in wireless headphone capability. Makro uses a proprietary low latency system that exhibits no discernible lag at all. A really nice thing about being proprietary is there is no pairing process. All you have to do is enable the wireless feature on the control box, turn on the headphones, and boom, you are in business. The downside is you only have one choice of headphones – the included Makro wireless headphones. These are a nice, light set of phones but they are just a bit too small to fit over most people ears. I have fairly small ears and they still rest on instead of over my ear. The sound quality is good, but like most wireless headphones they seem less “bright” than wired headphones. All in all the wireless headphones are quite good however and a pleasure to use.

    Makro wireless headphones
    The Makro Gold Kruzer does have a waterproof speaker with decent volume that can be used instead of the wireless headphones. If you prefer other headphone options, be sure and get the optional waterproof port to ¼” headphone adapter cable. This cable attaches to the same port used for charging and software updates and allows any wired headphones to be adapted to the Gold Kruzer.
    The LCD display is well laid out with a very large target id number displayed. The other setting indicators might be a little harder for those with poor eyesight to make out, but should present no issues once the layout is learned. One big change from the Gold Racer is that the four large navigation buttons, trigger switch, and rotary dial power / volume switch have all been replaced by ten small buttons on the control panel. All the buttons can be reached and controlled by the operators thumb, but the small size and closeness of the buttons may make for some navigation errors early on, and especially when trying to change settings underwater or with gloves on.

    Makro Gold Kruzer display and controls
    The Makro Gold Kruzer User Manual is available for download so I will refer you there for all the little details. What you have in the Makro Gold Kruzer is a hot 61 kHz metal detector waterproof to 5 meters (16.4 feet). The Gen (General) mode is a fairly standard VCO audio all metal gold nugget detecting circuit. The Gold Kruzer in Gen mode is very reminiscent of other hot gold nugget detectors running in the all metal prospecting mode.
    The Gen mode acts exactly like one would expect a threshold based all metal mode to function. There is a nice smooth threshold that gives feedback about the ground and reacts to hot rocks with classic nulling signals and small nuggets with that classic “zip-zip” VCO audio. Voltage Controlled Oscillator (VCO) audio increases both in volume and pitch when a target is detected, giving a distinct response very common on many gold detectors. The only thing different here is that since the Gold Kruzer has an LCD readout; you can get target id number results while running in all metal Gen mode. The audio is far more sensitive than the meter however, so do not be surprised if the deepest and smallest of targets give no target id information.
    In a break with the Gold Racer the Fast and Boost modes are not dual tone modes, but instead are silent search (no threshold) single tone modes. Items either signal audibly or not based on the current discrimination settings. The discrimination setting, like that of the Gold Racer, is a simple up and down control. Everything above the setting gives an audio signal of “beep”. Anything below the discrimination setting level is rejected or ignored with no sound at all. The Gold Kruzer has no notching capability i.e. the ability to pick and choose individual target id numbers for rejection.
    Fast mode is just what it sounds like – a fast setting for working in really dense trash. Target recovery speed has been increased at the expense of outright depth, but sheer depth is useless where target masking is the main problem. Boost mode is exactly the opposite. Boost is the deepest discrimination mode on the Gold Kruzer but due to the increased sensitivity is more suitable for less mineralized ground and sparser targets.

    It should be obvious that the Makro Gold Kruzer is all about gold. This explains the shift from dual tone to monotone audio in the Fast and Boost. Dual tones as employed in the Makro Gold Kruzer can be problematic when hunting the smallest gold targets, especially in highly mineralized ground. It is hard for a detector to get a clean separation of ferrous and non-ferrous targets when the targets are very small.
    This is because the actual dividing line between ferrous and non-ferrous is not a line at all, but a zone. The Makro Gold Kruzer uses a fairly standard discrimination scale that ranges from 0 – 99. The range from 0 – 40 is considered to be the ferrous range, and 41 and above non-ferrous.
    Yet the discrimination default for both the Fast and Boost modes is 25. This is because if you bury small gold in highly mineralized ground or large gold extra deep in mineralized ground, the ferrous ground signal can overwhelm the very weak non-ferrous signal. It really is not about the object size. A deep large nugget is a very weak signal just the same as a shallower small nugget, and either can end up reading as a ferrous target.
    The solution is to lower the discrimination setting into the ferrous range and accept that you have to dig some ferrous items to get all the gold items. This actually applies to any metal detecting. If you dig absolutely no ferrous trash, you are almost 100% guaranteed to be passing up some non-ferrous items reading incorrectly as ferrous. This can be acceptable of course depending on what you are doing, but passing on a deep six ounce gold nugget because it reads ferrous can be an expensive mistake. The Gold Kruzer default discrimination setting for Fast and Boost is 25 instead of 40 for this very reason.
    Dual tones have issues for this same reason, with decisive results on the weakest targets difficult if not impossible to obtain. The difference is quite small, but monotone is slightly more stable and proficient at working with the tiniest and faintest of signals right at the dividing line between ferrous and non-ferrous, wherever you have set the control to tell the Gold Kruzer where that line is for your particular situation. There is no pat answer as the where to set the discrimination control. It is a judgment call based on experience, but when in doubt, use less discrimination and dig more trash. Welcome to gold detecting!

    The Makro Gold Kruzer has a new control that relates to this overlap between ferrous and non-ferrous readings. The Extra Underground Depth (E.U.D.) control acts to directly impact the tipping point between ferrous and non-ferrous readings. The E.U.D. control only works in one of the three discrimination modes and when used on a suspect target that is reading ferrous may reveal by a different tone that it is actually non-ferrous. It is noted in the manual that it can reveal some targets misidentified as ferrous, but it will also give more false positives on ferrous targets.
    I was unable in the time allowed to figure out just how efficient this control is. In theory you can just set the discrimination lower, digging more ferrous but getting those missed non-ferrous items. Or set the discrimination a little higher, and now examine suspect targets individually by engaging the E.U.D. control momentarily. Finally, you can run E.U.D. on at all times. Is higher disc with E.U.D. on at all times going to get better results than just using a lower discrimination setting? Sadly, I just do not know at this time. I do know it is no magic bullet so the efficiency of employing the E.U.D. control will have to be determined over time by users around the world
    What? You say you wanted tones? Well, the Makro Gold Kruzer has you covered. The new Micro mode is a three tone mode similar to that on other company models, but running at that hot 61 khz. The 0 – 40 target id range produces a low tone. The 41 – 66 range produces a medium tone, and 67 – 99 range a high tone.
    Micro mode allows the “ferrous break point” to be adjusted. This is that magic point where you decide what is going to read as ferrous and what reads as non-ferrous. Note that unlike the Fast and Boost modes, the default ferrous breakpoint is set at 40 instead of 25. This is good for coin type detecting but again may be too high for other types of detecting. While in Micro mode you may use the Tone Break control to vary this all important setting. You could mimic the other two modes by setting the Tone Break at 25. Now 0 – 25 will be a low tone, 26 – 66 a medium tone, and 67 – 99 a high tone.
    Tone Break can only be used to set the ferrous breakpoint. The upper high tone region of 67 – 99 is preset and fixed by the factory with no adjustment possible.
    You may use the Ferrous Volume setting to control how loud the low tone response is. The medium and high tone responses are set with the main volume control.
    The discrimination control still functions in Micro mode, with a default setting of ten. Hot rocks and ground responses occur this low on the scale, and so having at least some of the low end blocked or rejected with reduce the number of low tone responses generated by the ground itself. The control can be set as high as you want and will override the other settings, blocking all targets below the desired target id setting.
    The Makro Gold Kruzer does have a tone control, but it does not allow the tones to be changed in Micro mode. Those are factory preset, with the Tone Break between ferrous and non-ferrous plus Ferrous Volume as the two adjustments you can make. The Tone setting allows the tone of the audio response and threshold to be changed in Gen, Fast, and Boost modes only.
    Micro was designed first for hunting micro jewelry. Micro jewelry is a loose term that applies to all very small jewelry items, like very thin chains, single post earrings, tie tacks, etc. Micro is perfect for hunting tot lots and beaches and focusing on the “gold range” targets represented by the mid tone reading in Micro mode. Many jewelry hunters consider digging coins a waste of time, and so ignoring high tones can save digging pocket change when the real goal is a woman’s diamond and platinum ring.
    The Makro Gold Kruzer has a nominal non-ferrous range of 41 – 99 which is a 59 point spread. Normal U.S. coin responses are 63 for a nickel, 83 for a zinc penny, 84 for a copper penny, 86 for a clad dime, and 91 for a clad quarter. The high 61 kHz operating frequency acts to push target id numbers higher and most coins will respond at 83 and higher. I was surprised a zinc penny and copper penny for all intents read the same.
    The good news is the low conductor range is expanded, which offers the ability to help discern different pull tabs and other trash items over a wider range. This in turn may help eliminate at least a few pesky trash items while hunting gold, although ignoring gold range items of any sort can be risky. Still, with a U.S. nickel reading at 63 and most women’s rings reading under the nickel, you get the 40 – 63 zone as a 23 point range where much of the most valuable jewelry will turn up. The default high tone breakpoint of 66 – 67 is clearly focusing the Gold Kruzer mid-tone on this very important gold range. Do note that large men’s rings and nearly all larger silver jewelry will read above 66 and therefore give a high tone reading.
    The Gold Kruzer has some obvious applications but there are a couple catches. First, it is running at 61 kHz, which means it is very hot on low conductors, but that it will have just adequate performance on high conductors like silver coins. Second, its extreme sensitivity to low conductors means it will not work well if at all in saltwater or on wet salt sand. Saltwater is a low conductor and will respond quite strongly on the Gold Kruzer, and getting it to not respond to saltwater gives up all the sensitivity to small gold. The Gold Kruzer will work very well around freshwater or on dry sand, it is not intended as a detector for use in or near saltwater. I would suggest the new Makro Multi Kruzer as an alternative to those who want to hunt in and around saltwater on a regular basis.

    There are many features I could delve into but at over six pages this report is getting long, so I will again refer people to the User Manual for the details. Suffice it to say that the Makro Gold Kruzer has a full set of features like frequency shift for reducing interference, temporary audio boost for the Gen all metal mode, adjustable backlight, and the ability to save settings when the detector is powered down, and more.
    I got the Gold Kruzer prototype during a period when I was quite busy and the weather was not helping. I did have time to do a few tot lot hunts plus make a trip to the goldfields to evaluate the machine. The Gold Kruzer is well behaved in urban locations, with only a little static from electrical interference sources. I found the new Micro mode to be just the ticket for quickly blasting through a tot lot recovering prime gold range targets. I dug everything as is my practice when learning a detector, and ended up with the usual pile of aluminum foil, junk jewelry, and coins. Nothing special found but no doubt in my mind that the Gold Kruzer acts as intended in this type of setting.
    There were no surprises in the goldfields. At 61 kHz and in Gen mode the Gold Kruzer is a real pleasure to run, with all the response and nuance one expects from a great threshold based all metal circuit. Boost Mode also works very well as an alternative for small nugget detecting. I had no problem at all finding a couple little bits of gold weighing under a grain (480 grains per Troy ounce) on my first and only nugget hunt so far with the Gold Kruzer.

    Two tiny gold nuggets found with Makro Gold Kruzer
    To sum up, the new Makro Gold Kruzer once again ups the ante at Makro. It comes standard with two coils and is fully waterproof for about the same price as the Makro Gold Racer so I would have to assume the Gold Racers days are numbered. The one thing I am not sure about at this time is that the Gold Racer has a 15” x 13” DD coil option. The Makro Multi Kruzer has the 15” coil option, but no such accessory has yet been announced for the Gold Kruzer. This is probably not a concern for very many people, but it bears mentioning. May 2019 Note: The Makro Gold Racer is still in production but the price was lowered to $509. Nokta/Makro have also produced a 15.5" x 13" coil option for the Gold Kruzer.
    I have no problem at all recommending that anyone interested in a detector with a focus on gold take a very serious look at the new Makro Gold Kruzer. It’s performance on low conductors of any type means that the Gold Kruzer is not just for prospectors and jewelry hunters but may also see favor with some relic hunters who focus of low conductor targets like buttons and bullets. This is a solid detector with 21st century features at a very attractive price.

    There are a few key things to know about headphones for use with metal detectors. The most important thing is to know that some detectors operate in mono, and some in stereo. If you mismatch headphones you can end up with audio in one ear only, or none at all. In fact, this has happened to me. I took my White's DFX out to do a little detecting, and grabbed an old pair of Fisher Phones I had around, and when I got out I found the phones would not work on the DFX. So most detector phones have a stereo/mono switch, or are specially wired to work either way. Make sure your headphones match your detector for stereo or mono operation. But best case is to only use headphones that can do both so you can use them with any detector. You never know when they might get put to use on a different machine. In a situation where you are determined to use a mono headset on a stereo detector or vice-versa plug in adapters can be purchased at most electronics supply houses.
    99% of the detectors out there have a 1/4" headphone plug, but many generic headphones have a 1/8" plug. Sure, you can use an adapter, but it just adds a weak spot in the system. So get a 1/4" plug unless your detector is one of the rare 1/8" models. Again, pay attention to the mono versus stereo issue. The good news is that if you make a mistake there is almost always an adapter that will fix the problem but it is best to try and get the correct match.
    Does your detector have a volume control? Many do not. It is best to buy headphones that have their own volume controls, so you can use them with detectors that do not have a volume control. Again, you never know when you might switch detectors.
    Ohm matching can be important, and generally higher ohms is better. This is not always true however and some detectors do work better with lower ohm rated models. It is usually easy to determine what the headphone ohm is but almost impossible to know what the detector rating is. I therefore recommend that you should have your detector in hand and be trying the headphones before you buy them instead of going by specs on this point.
    Things to look for:
    1. How do they sound? Are targets sharp and clear to your ear? If not, you can now pass on this set and try another. Different headphones match up with different machine and different ears in such a way that nothing short of trying them can sort this point out. They either sound good to you personally, or they do not. It does not matter what your friend likes. Some detectors allow you to change the pitch from high to low. Try different pitches with your detector to see what sounds best. How do faint targets sound to your ear? People have different frequency responses, some like low tones and some high, and the type of speaker wired into the headphone can make this sound vary a lot. Get a set of headphones that make faint signals as clear as possible to your particular ear.
    2. Assuming they sound good, how adjustable is the volume? A good match will give you the ability to fine tune the sound with the volume control on the headphone. In other words, the volume control will have some range. If you have very high ohm headphones and use them on a high volume machine that has no volume control, the headphones may be so loud you have to set the volume on the headphone nearly off. And then tweak it within a fraction of a turn. Some headphones are too powerful for some detectors! The volume control should run from off at one end and too loud at the other, with lots of adjustment in between.
    3. How many volume controls are there? Some people like two, one for each ear. This can be great if you have poor hearing in one ear and need to compensate. I personally prefer a single control that works both ears at the same time, so I do not need to fiddle two controls. So this is a personal preference thing, but your headphones should have one or two headphone volume controls. A note on setting your headphones. Turn the detector volume all the way up, if it has a volume control. Turn your headphones all the way down, then turn on your machine and wave it over a large metal item. Turn the headphones up until the loudest sound you will get over a large item is not so loud as to damage your hearing. Now, set the threshold sound on your detector for a faint buzz. You should now be able to hear faint variations in the threshold, but going over a 55 gallon drum will not damage your hearing.

    4. How well do the phones exclude outside noises? Normally, get a set of headphones that will exclude outside noises like running water, wind in the trees, or anything else that might distract you from the detector sounds. Sometimes it may be advantageous to use phones that let you hear outside noises, like in bear or snake country. Or maybe in real hot climates bulky units get too warm. But from a pure detecting standpoint sound excluding headphones are best. Earbuds are perfectly acceptable however for quieter locations.
    5. How well do the headphones fit and feel? Imagine they are going to be on your head for 12 hours. Something that feels good initially can feel pretty bad in a few hours. Beware of headphones that are too tight or that have too little padding. I prefer phones that completely cover my ear and seal to the side of my head. I do not like the kind that squash my ear but people's preferences vary. Make sure your headphones are comfortable for long hours of use.
    6. How tough do the headphones appear to be? This can be hard to gauge sometimes, but in general avoid anything that looks to have cheap construction. The number one failure point is the cord, so make sure it is strong and well anchored so it cannot pull out. Headphones that feature a 90 degree plug are often desired to reduce strain and prevent the plug from pulling out due to a simple tug on the cord.Some top end models feature replaceable cords so you can carry a spare. I prefer to simply carry a complete spare set of headphones.
    7. Finally, be aware that the newest metal detectors are coming equipped with built in wireless headphone capability. Early versions have either been standard Bluetooth, which is too slow, or some faster proprietary method. Standard Bluetooth has a significant lag between detecting a target and the actual audio response heard in the headphone which is bothersome to most people. The problem with proprietary is that you are stuck with very limited options as to headphones. The best option currently for most people is aptX Low Latency (aptX LL) Bluetooth, which is fast enough that most people are satisfied with the speed, and options abound in the choice and style of headphones.
    To sum up, if buying headphones at Big Box Inc. at the least you'd probably want a set with a stereo/mono switch, 1/4" jack, and volume control/controls just to make sure it will work on most any detector. But remember that headphones are like tires for an expensive sports car. They are one of the only important items on a detector you can customize for optimum performance, the other being search coils. Finding the set of headphones that is just right for you can make a real difference in detecting success, so it deserves some effort in getting the right set. This is where a local dealer with a good selection who is willing to let you try them all out on your detector can really help you out.

    Where Do I Begin? by Ron Wendt
    You’ve developed an interest in prospecting for gold. A couple friends have told you how much fun they’ve had looking for gold. In this article I’ll point out the pros and cons about this activity and in the end you’ll probably have decided to what degree you want to pursue your search for gold. To begin with, it must be pointed out, there are several types of prospectors:
    1 - Those who wish to dig right in as a recreational prospector.
    2 - One who is serious about learning about the finer aspects of geology related to precious metals and would pursue possibly developing potential income from this endeavor.
    3 - A hardcore, hand miner “give me a bulldozer, I wanna gamble.” Of course mining can be a gamble and the biggest mistake some folks make is getting too serious about it. Many times most of the fun goes right out the window when it becomes serious. What happens is the deep desire for gold becomes elusive and discouragement sets in when there are no results.
    Looking for gold can be hard work with few rewards. Years ago an old timer once told me; “the fellows that got rich during the gold rush were just plain lucky!” Napoleon once said that too: “I want good generals, but I also want lucky ones!” Yes, there is a lot of luck in this business. The old timer and Napoleon were right. A lot of it is luck, but a lot of it is hard work to. You can choose to enjoy it with a little reward or to not enjoy it with little reward. The truth is the odds are you won’t get rich, but you might get lucky! We all know about luck. You can go to the gambling hall and pull on the “one armed bandit,” all day and not make a dime. Such is mining and prospecting. I’ve been lucky and I’ve been unlucky. I’ve been rich and I’ve been poor. I like rich better, and I like getting lucky.

    Shoveling gold bearing dirt into power sluices
    To be a prospector you must be willing to take a risk to a certain degree. There are those who think they can go out and simply put their shovel into the ground and there it is! They believe they’ll strike it rich. I have known some who have struck it big their first few times out. They didn’t have a clue, but were in the right place at the right time. There are several things in your character you should be aware of.
    1 - You should be the type of person not easily discouraged.
    2 - You should not be afraid of getting dirty and not afraid of hard work.
    3 - You should have a keen interest in exploring, prospecting things that are related in this field because it is all connected.
    4 - Be frugal. Don’t mortgage the farm. It doesn’t take much in the way of investment to get into this “field of study,” as I call it.
    5 - You should not be afraid to get wet, camp out, or endure the elements.
    6 - Attitude is a major in this business of mining/prospecting. This probably goes along with “don’t be easily discouraged.”
    7 - Don’t be afraid to fail. Failure is a great learning experience.
    8 - Have some curiosity about what could be over the next hill or under the next rock.
    9 - Be optimistic. If you’re not, you probably shouldn’t be in this business.
    10 - Most of all enjoy it. Enjoy it even though you don’t get rich from it. Your reward is experience and experiences many will never have the opportunity to do.
    Where do I begin? First off don’t go out and buy a bulldozer, when a gold pan can simply do the trick. In other words, start out learning the basics. Those basics are the gold pan, pick, shovel, sluice box, and perhaps a sniffer bottle to suck up gold from cracks. It would be good to go along with a veteran, not only to see how it’s done but to see if you like it. I have seen many times where folks will go out and buy a $1,500 suction dredge only to sell it the next year because they probably got discouraged, when a gold pan and hand tools would have sufficed. A big majority of prospectors I know will tell you they started out small, by that I mean, small mining tools which would include sluices, gold pans, picks and shovels. Once you decide you will make prospecting your side line, one can eventually branch out into other methods.

    Dredging for gold
    There are some who will head out into the world of nugget detecting. Here’s something to think about. When you spend $600 to $1,000 on a brand name detector, before you even make a decision to buy it, ask yourself this; “Where will I use it?” This may seem like a funny question, but in Alaska and the Yukon Territory, we may have a lot of gold scattered around up here, but is it detectable and accessible? Will I be able to drive somewhere during my time off from my regular job and spend enough time detecting nuggets? Is there a location close by where gold is detectable? Am I willing to invest this kind of money to use this machine in a proven area?
    There’s nothing worse than buying a piece of mining equipment and not be able to get into areas that are productive. For instance, the mountains behind my house generally yields mostly fine gold and some hardrock gold. For me to get any bigger gold I must travel south of my house about two hours down the highway or 5 to 10 hours to the north to get into productive ground. I am willing to spend times going to my favorite remote spots in search of gold. So you must determine how much am I willing to put into this to get results? It’s the same with going from your gold pan/sluice operation to a high banker or a suction dredge. Are you planning on a few choice trips to areas to get results, which by the way aren’t guaranteed?
    My recommendation is build up your knowledge of prospecting over 2 or 3 years before investing in bigger toys. This way once you’ve established a good, possible gold source, you might feel it’s now time to go for higher production. Large scale industrial miners work in much the same way. I have a good friend who suction dredged for a few years on a creek. After taking out numerous ounces of gold, he made a decision to go bigger. From there he bought a small D-6Cat to feed a sluice box, then eventually he added a backhoe. Today he has a D-9, a bigger backhoe and a dragline. He’s been seriously at it for over 25 years. In the off season he has another job to support his “sickness” called “gold fever.”

    Gold found by a prospector
    I’ve met a few folks who complained: “Yeah, I went out for a couple hours, and didn’t get a thing. There’s nothing out there!” He immediately was very skeptical there was any gold at all out there.” I said that was fine. There’ll be more for the rest of us! I told this fellow, a couple hours does not do the trick. You have to work at it. It won’t jump up into your pan, and no one will tell you exactly where it is because they don’t know themselves where it is exactly. We have an idea, but we can’t always pin point it. Most of the time we walk right over it. I remember an old prospector from up on the Yukon River was once asked where he kept all his gold, to which he replied; “Its in a safe place in the creek!” He knew he could dig it out anytime he wanted to, but he had to make the effort. No one would get it for him. He took out enough gold to survive on most of his life. It was his lifestyle and sole occupation.
    Finally, recapping everything, I can’t stress enough:
    1 - Start small, then gradually increase your devices to accommodate your potential production. You might advance from a sluice/gold pan to a nugget detector. You might eventually obtain all the tools of the trade, short of buying a bull dozer. The bull dozer purchase would probably indicate you’re pretty serious or you’ve got money to blow!
    2 - Enjoy this endeavor. If you don’t enjoy it, get out of the business. You probably should not have gotten into it.
    3 - There’s no room for discouragement. If you’re easily disappointed then prospecting is probably not for you.
    4 - Expect to work hard at it. Be patient. Patience is a virtue. You will put in time of no rewards, but when they come, it’s worth it all.
    5 - Don’t get greedy. If you hit it big, a few ounces here and there or bigger, consider it your much deserved reward.
    6 - Don’t mortgage the farm. Never, never do this! I’ve known miners to put all their eggs in one basket and they all cracked! Unless you like living in tents on the edge of town, never gamble with your stability.
    7 - Enjoy prospecting. Its one of the most fascinating occupations I can think of. What better way to enjoy the outdoors, splash around in cold water on hot days, explore old ghost towns, collect rocks, view big game, there are folks that would give their right arm to do this.
    A word of encouragement to those in search of gold: Practice patience, be optimistic. Always learn from your mistakes and always keep enough bug dope in your pack!

    Note from Steve Herschbach - Ron was a dear friend who left this world too soon. He donated this article for use on the website not too long before his health finally failed. We all miss you Ron! R.I.P. Ron Wendt 1956 - 2007
    From the obituary:
    Ron Wendt was born April 24, 1956, in Fairbanks, in the Territory of Alaska. He was raised on his family’s homestead on Chena Hot Springs Road outside of Fairbanks and his father’s mining claims in the Circle gold fields. He developed an early interest in Alaska history by exploring ghost towns and mining camps and talking with old-timers from the gold rush era.
    Ron worked as a gold miner, newspaper reporter, photographer, college instructor, construction worker and custodian before starting his own publishing business, Goldstream Publications, in Wasilla. He wrote about gold rush history, modern day mining and prospecting, and many tales of Alaska. He was a member of the Alaska Miners Association, an avid baseball fan and loved to travel the roads of Alaska with his wife, Bonnie.
