  1. People often forget about factory reset functions since it is still a rare feature. I am a proponent of resetting newer generation digital metal detectors on a regular basis, especially if settings get changed around a lot. The more setting changes are made, the more chance of a programming bug slipping in and messing with the operator. This is the procedure for the many F75 variants out there. From the F75 Owner's Manual page 10: RESET function The F75’s microprocessor saves all settings which you input, even after the power is turned off. If you wish to reset the settings to the factory preset, follow this process: Turn detector off. Press-and-hold the red MENU button and push-forward-and-hold the TOGGLE SWITCH. Turn the detector on, while you are still holding the controls. Release the MENU button and TOGGLE SWITCH. See the F symbol. When the F disappears, the detector is reset. Note: some latest F75 versions may show five pairs of number instead before displaying the F - the ten digit serial number. All settings have now been returned to factory defaults.

  2. I have seen gold read anywhere from in the ferrous range all the way up to where an aluminum can reads. In other words, over nearly the entire target id scale, from smallest to largest. The sweet spot for women's rings is below U.S. nickel in the foil range and definitely not a range to exclude. The sweet spot for men's rings is above U.S. nickel where most large pull tabs read. The immediate nickel range is actually a weak spot for gold rings, too high for most women's rings, and too low for most men's rings. That is not to say rings do not appear in the nickel range, just that it is not a hot range for gold rings. Target ID / VDI Numbers For Gold Nuggets And Gold Jewelry There is no way anyone will break me from associating U.S. nickels with gold. I use it as a reference point when jewelry detecting exactly because of where a nickel reading relates both to men's and women's rings. For nugget detecting a U.S. nickel provides an excellent reference point for detector performance comparisons by being a standard and easily obtainable item that falls squarely where one would expect nuggets weighing several grams to appear. Therefore just like a dime being a reference for people hunting silver, a nickel provides a standard reference for people hunting gold. The metal/alloy mix makes no difference - all that matters is the size and target id number. Detectors know nothing about metals and alloys, and anything that reads just like a nickel, whether it is a pull tab beavertail, eraser holder, lead bullet, or gold nugget is all the same as far as the detector is concerned. Gold nuggets are an alloy also, the most common metal in a nugget after silver being copper. My standard references are ferrous, nickel, and zinc penny which act to divide the target id range into three useful "zones": Ferrous Small gold nuggets, necklaces, ear rings, women's rings (and tons of small aluminum trash) U.S. nickel Men's gold rings, larger gold nuggets (pull tabs, larger aluminum trash) Zinc penny Silver and copper coins, silver jewlery For small gold items including women's rings I will concentrate on the zone between ferrous and nickel. For larger gold jewelry I focus on the range between nickel and zinc penny. For silver and copper coins it is anything above zinc penny. This is quick and dirty but with any detector tell me where ferrous, nickel, and zinc penny read, and I can figure out all the rest.

    Fisher F75 Factory Reset Procedure

    Well, the T2 has no ability to save settings, and so it does come on in factory default settings every time you power up. That is not the same as doing a factory reset however, and so while you will not see any settings revert on the T2 when doing a factory reset it is still not a bad idea.

    Hacking The White's V3i

    Sounds like a really great project. The possibility you are one of the only people in existence that can give this early (first?) communication system a real life test makes it all the more exciting. Thank you for anything you share on the subject.
  5. The Minelab Equinox Series "From Beginner to Advanced" by Clive Clynick is the first book available about the new Minelab Equinox metal detectors. The 8.5" x 5.5" format book is 111 pages of densely packed information that is intended to help new Minelab Equinox owners get the best out of their new detectors. The early part of the book relies of screen shots to illustrate the various controls on the detector, and then switches to hand drawn pictures to illustrate various concepts described in the book. In this day and age of slick graphics the hand drawn images lend a "homemade" feeling to these books. That is indeed probably the case since the book is in the "fold and staple spine" format favored by those printing books at home. I can't really fault Clive for using the hand drawn images however. A picture does often easily get across some idea that might be very difficult to describe in writing. I personally can sketch out a useful image quite easily, but turning that sketch onto a slick computer generated diagram can be time consuming. In the end the hand drawn sketches get the idea across, and that is what matters most. The first roughly 40 pages of the book basically go over the controls, adding some details not found in the owner's' manual. The real meat is in the last 70 pages of the book. Clive goes into great detail emphasizing important details about the Minelab Equinox meter and audio characteristics. There is a lot of information here about how to use the Equinox features along with good handling skills to get the best performance possible out of the Equinox. The book has an emphasis on coin and jewelry detecting both on dry land and beach. I therefore think the book will be of most use to people looking for information more specific to these subjects. Information specific to relic detecting or nugget hunting in particular is more in passing while discussing coin and jewelry detecting. Much of the information presented does assume basic detecting knowledge along with basic knowledge from the Equinox owner's manual. Clive tries to avoid repeating information already found in the owner's manual, and so from this perspective I would rate this book as being applicable for detectorists with moderate to advanced detecting skills. People who are totally new to detecting may feel in a bit over their heads initially. That is fine because any detecting book worth having usually needs more than one reading. Things that do not sink in at first make more sense after getting some hours of experience before they "click". The book may be challenging for true beginners on the first go, but that is because there is meat here to satisfy more advanced operators. Anyone that perseveres with fully understanding the information in this book will no longer be a beginner, and the good thing is the skills learned will apply to many other high performance metal detectors. The bottom line is I recommend this book for people looking for information that goes far beyond what is offered in the Equinox Owner's Manual, and which is of primary interest to coin and jewelry hunters. Clive is an accomplished writer with several titles to his credit that qualify as "classics", especially as regards jewelry detecting. Visit his website at http://www.clivesgoldpage.com/ to see all the titles he currently has available.

    Do You Remember Your Old Detectors?

    November 25, 1972 I sent a letter to my mom. I was 14 years old and just got my first metal detector and mailed a copy of the ad with the letter. My mom gave me the letter and ad back recently... My first detector in 1972 - a White's Coinmaster 4 TR for $199.50 (a lot of money then, especially for a 14 year old!).... And from the letter, my very first detecting report... "I went hunting at Goose Lake and Elderberry Park for coins. I only went hunting five times and I've found: One 1964 silver quarter, seven silver dimes, including one 1936 mercury dime, four ordinary dimes, six nickels including one 1943 and one 1944 silver nickels from during the war, thirty pennies, the oldest a 1946, two bullet shells and one bullet, some parts of necklaces, and 10 billion pop can lids, gum wrappers, etc." No discrimination yet in 1972, and aluminum was already showing up in quantity. Only a couple inches of depth, but as one of the first guys on the ground with a detector locally it was easier to find silver in those days then it is now. I also mention in the letter I am saving up to buy my first gold dredge, a 3" Keene with no floats, for $379 new plus shipping. So my first detector in 1972 followed by my first gold dredge in 1973.

    My First Equinox Gold Nuggets

    OK, I am warning you all up front - I still am going to be wishy-washy or outright avoidant of certain details still. The dam is cracking but not burst yet. Here are the results of a test run with the new multifrequency (MF) option in Gold Mode. I am battling limited time and weather issues so was actually quite pleased to find any gold at all - a few lead bits often tells me just as much, so the gold is a sort of bonus. Anyway, Equinox 800, Gold Mode, MF, relatively mild ground and so I was pushing sensitivity levels high, 22 - 25. Three nuggets, two of only 0.6 grain each (480 grains per ounce) and one 9.8 grains (0.6 gram). The 0.6 grain nuggets are one smaller, fatter one plus one thin flake. What most impresses me about these are not the gold per se. It is the fact these were found with an 11" round DD coil. I am not in a position to be able to excavate these like an archeologist to determine the exact depth they were found at but I can guesstimate based on the holes and sounds. The two tiny bits were found at 1-2 inches, and the 9.8 grain nugget at 3-4 inches. Just based on this alone and many years of nugget detecting I can tell you the Equinox can hunt gold just fine. How will it stack up against dedicated gold nugget detectors? Frankly, in my opinion that will be determined largely by coils. Operationally I much prefer the 6" x 10" DD on my Gold Monster and hope such a coil becomes available for Equinox. The 11" open web will be "OK" but not a great prospecting coil design which is why no dedicated gold detectors come with one. It hangs up on protruding rocks and stubble and so a solid design would be better, or at least a solid scuff cover. The large coil will false on rocks if struck will at the highest sensitivity levels and low recovery speeds while in Gold Mode and the extra edges just accentuate that tendency. The 6" coil will be nice but more for spot work as covering acres at a time with a 6" round coil....... I want the elliptical. Long story short my Gold Monster is not going anywhere quite yet, but only because of the coil. The big coil can find small gold however, and should give great performance on larger nuggets at depth, more than an elliptical will get. For a VLF however - always keep that in mind. This is not a Minelab PI or GPZ 7000.

    My First Equinox Gold Nuggets

    I have been acquainted with the Equinox longer than most people and so I am not sure it is a fair question since some would say I helped create the hype! Nothing in my opinion about the Equinox has changed since February except that I have more respect for it than ever. The Equinox has replaced all my "in use" detectors except my GPZ 7000.
  11. I tripped over this extensive article, available as a free download. Here is the abstract: The article sets out to clarify the special character of the North American gold pan and why it remains so popular – in spite of widespread dissatisfaction and many modifications and innovations. The North American pan is distinctive in being circular with a flattish floor ringed by an outwardly sloping wall. Its identity is confused by over-use of the terms 'pan' and 'panning'. The North American pan gyrates in a distinctive orbital motion driven by both hands of the panner. Although many other motions are resorted to (tapping, to-and-fro, tilting, and tick-tock), it is the orbital motion and flattish floor that together distinguish the pan from most other hand-held gravitational devices. In spite of its enduring popularity, no scientific tests have been published on the North American gold pan or for any of the innovations covered by 30 US patents awarded since 1861. It remains unclear if the North American gold pan is more efficient at recovering fine gold and flat gold than is a lotok, batea, dulang, ninja bowl, grizzly pan, mat, bucket or any other sort of hand-driven gravitational device. Some innovations are long-forgotten but merit attention. For instance, bars to keep the panners hand clear of the water, cables to hold large heavy pans, and several pans designed for panning without any water. Traditionally the North American gold pan was a combined digging and washing device, but today most models are not designed for digging and require a spade to be used.

  12. Published on Jul 25, 2018 - Some great tricks and tips from Gerry's Metal Detectors on how to use the whites 24k Goldmaster.
  13. Rege-PA just reported on the DP Forum that a new White's detector is on the way - the White's Goldmaster 24K. I have put a specification page together for the new model and will update it as information becomes available. In short it looks like an updated and slimmed down version of the GMT put into the new MX7 packaging. There is now a backlit LCD display with target id information, advanced ground tracking technology, dual tones, and more. The new Goldmaster 24K comes with both rechargeable batteries and a battery holder for eight AA batteries. The stock coil is the 6" x 10" DD and there is a two coil package option with the 6" x 10" DD and a 6" round concentric. The White's Goldmaster 24K announcement is so new that there are sure to be changes and updates to this page very soon - all information and specifications are subject to change! Check out the new White's Goldmaster 24K specification page New White's Goldmaster 24K metal detector
  14. I ground balance at the sensitivity setting I will be using. I think doing otherwise may result in an inaccurate ground balance setting.

    White’s Australian Dealer?

    Another forum member was wondering what the price of the new Goldmaster 24K might be in Australia. In the course of researching that, I see Goldsearch Australia is closing down. Does White’s have any other dealers in Australia?

    Why Are Some DD Coils As Big As Hula Hoops?

    The coil with the larger surface area generally gets more depth, all other factors being equal. Both length and width matter, not just length as you seem to be implying. A round 10” DD is normally going to get more depth than a 6” x 10” DD. Tech notes - About Searchcoils by Dave Johnson and Coil Basics by Carl Moreland

    Usefulness Of Fe304 Meters?

    Actually this is completely wrong John. Ground Phase (the ground balance number) relates the TYPE of mineralization, not the AMOUNT. The is the entire reason Dave Johnson added the Fe3O4 meter to the GMT and many of his designs that followed. The MXT does not have this feature. That is not to say the TYPE of ground mineralization does not matter, but what you are saying directly contradicts Dave Johnson (and others - see link below), and in this matter my bet is on him. GB Numbers = Mineralization?
  20. Our cup runneth over! Just a few years ago the market for "over 30 kHz nugget detectors" was quite limited. For a long time there were only a few options: Fisher Gold Bug 2 (71 kHz) $764 with one coil Minelab Eureka Gold (6.4, 20, & 60 kHz) Discontinued $1049 when new with one coil White's GMZ (50 kHz) Discontinued $499 when new with one coil White's GMT (48 khz) $729 with one coil Things were that way for over a decade. Then in 2015 Makro introduced the Gold Racer (56 kHz) $599 with one coil. Sister company Nokta released the AU Gold Finder (56 kHz) $799 with two coils Then in 2017 we see the Minelab Gold Monster 1000 (45 khz) at $799 with two coils. And although not a dedicated nugget detector, the Deus high frequency coil options (up to 80 kHz) were also released, $1520 for complete detector with one HF coil. Now in 2018 we get another general purpose machine, the Equinox 800, that can hit 40 khz, $899 with one coil. And just announced... the Makro Gold Kruzer (61 kHz) $749 with two coils and the White's Goldmaster 24K (48 khz) $749 with two coils These last two announcements have made barely a ripple in the prospecting world, or at least going by other forums that seems to be the case. There are various reason for that (forums not being prospecting oriented or being Minelab centric) but still the lack of buzz is interesting. I do believe people are both burned out by all the new introductions and that the market is saturated with high frequency models. Leaving out the general purpose machines to sum up the current options it looks like the current "sweet spot" for pricing is a high frequency model at $749 with two coils. Makro Gold Racer 56 kHz - $599 one coil White's Goldmaster 24K 48 kHz - $649 one coil White's GMT 48 khz - $729 one coil White's Goldmaster 24K 48 kHz - $749 two coils Makro Gold Kruzer 61 kHz - $749 two coils Fisher Gold Bug 2 71 kHz - $764 one coil Minelab Gold Monster 1000 45 kHz - $799 two coils Nokta AU Gold Finder 56 kHz - $799 two coils High Frequency Gold Nugget Detector Roundup

    White's Goldmaster 24K

    The White's Goldmaster 24K has been announced and will be available for purchase by the end of August 2018. 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. The White's GMK announcement is new and there may be changes and updates to this page - all information and specifications are subject to change! 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. 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. The detector is also available with a two coil package - the 6" x 10" DD and a 6" round concentric.
