  1. Very interesting Steve. I'm testing right now new polish metal detector RUTUS Alter 71: http://www.rutus.com.pl/en In this unit you can adjust frequency by 0.2kHz step from: 4.4kHz to 18kHz...
  2. Looks like whites xventure kids detector is being sold on ebay. Neat idea for christmas for children and grandkids to start to learn to hunt with. http://www.ebay.com/itm/White-s-XVenture-Kid-s-Metal-Detector-800-0348/142271187819?
  3. Anybody seen the latest in metal detectors from DRS Electronics, their new Ground expert machine is just awesome. If it can do what they claim it can it might be a real game changer for metal detecting.
  4. I thought I would take a few minutes here and talk about the Signum MFT detector. My unit seems to have (looking at screen at turn on) the original version software. I have used the detector with the stock supplied coil,,it measures approx 11.5" in diameter. This coil is deep,,7khz freq, but due to size it can be cumbersome to use in places. Using the stock coil,,,bumping it will cause some falsing at times,,,running gain at 6,, sensitivity at 11. It in my soil is for a metered Vlf detector,,just maybe be my deepest on a clad US dime. The ground balance while using this detector,,very critical to get good to serious depth. Not hard to ground balance as long as you have some clean ground-- this can be a pain btw sometimes. It seems in my ground here,,,using turbo is really not effective,,,like a lot of other units with boost. But even saying this,,this detector features an economy power transmit setting as well as economy off setting. This economy off setting here combined with a sensitivy level of around 11,, gets down in the ground. This detector IMO,,sweep speed wise not overly forgiving,,at least with stock coil. This detector does possess a feature where the recovery speed can be increased,,called mm mode. Since I have been putting in most of my time with the Nokta Impact detector,,I do need more time with this detector. I happened to see a gent who was selling a smaller the stock coil (6x10") Mars coil,,so I bought. In case some folks here don't know,,,the coils used on AKA Sorex detector are interchangeable here with Signum detectors. Well today I took this new to me coil to a site,,to try. I was very impressed with this coil,,,as long as I was in mm mode. It seemed if I was running in normal mode,,,the detector couldn't keep up with the ground,,and even some of the iron and targets. I need to operate some more,,,I could be jumping the gun here by criticizing it. This detector and coil combo(my new to me coil) feels real nice,,balance and weight. This coil being 14khz,,,it nails higher conductors big time,,,some coins rather deep using this coil,,a user might think they were only a couple inches deep. The audio this detector possesses,,,is second to none in my book. One detector with such great audio,,,a user will not be overwhelmed even when running all metal in a super duper bad site with iron and nails. I did even today try and dig a few lower conductors,,that had a straight line on the holograph display. Even some of the lower conductors that had just a tinge of a loop in their graph reading. And sure enough these kinds of targets were low conductors but not worthy at all,,,edges irregular, inconsistent thickness, etc. I certainly would recommend the detector to a person,,,but with a 10" coil or smaller. Not a hard detector to operate either,,,sets up a lot like a White's V3i as far as the all metal side,,and the disc side of the houses (sensitivity wise). The pinpoint on this detector,,and I have owned a Sorex as well,,,both have the hottest pinpoint functions I have ever seen. Luckily they are adjustable so it can be turned down sensitivity wise. Similar ID screens are used I think with Xp Deus (secret screen, version 3.2) and White's Vx3 and V3i models. The Signum will give high tone on iron false,,,a user if they will watch screen will start to see a pattern to recognize iron falses. The tones are adjustable,,I haven't adjusted mine. This detector also has a way to check for bottlecaps,,has helped me. I even used this same feature today to weed out a bigger piece of cast iron. If a person here gets a chance to be around either a Sorex or one of the Signum models,,at least try to listen to the audio they possess. I am posting this info here as strictly a user of detector.
  5. First Texas owns Bounty Hunter, Fisher, and Teknetics. You see a lot of models drift from one line to the other. Teknetics is releasing three "new" models at low prices. Capitalizing on the current "made in America" trend, they are calling these the AmeriTEKs. Three models, the Minuteman at $249, Liberator at $349, and Patriot at $449. Internet prices will probably be 15% lower. I am guessing the Minuteman is a repackaged EuroTEK Pro and the Liberator a repackaged Land Ranger Pro but do keep in mind I am just making educated guesses. The one that more got my interest is the Teknetics Patriot model at $449. Teknetics Patriot 13 kHz Frequency Shift All Metals Auto-Tune Mode 0-99 Target-ID Target-ID Confidence Bar Ground Balance to Salt Push-button Static Pinpoint Speed Selection Non-Volatile Memory (Saved Settings) This appears to me to be a repackaged and much lower price Fisher F70 Check out the F70 specs and here are both screens side-by-side: Same screen, right down to the Fisher "wings"! The thing is the F70 currently goes for $649 and the Patriot will be heading out the door at under $400 - $381 if I got my discount right but they may set a MAP of $399 playing the price point game. $250 less than the F70 at the moment. And the Patriot looks to be sporting the more expensive 11" x 7" DD coil instead of the 10" elliptical concentric that comes stock on the F70. The F70 is a very powerful and underrated detector, overlooked by many because of the top-of-the-line F75. Dave Johnson is the metal detector engineer guru behind many of the great metal detectors we use. He frequents some forums under the name of woof! and here is what he has to say in a post on TreasureNet: "The F70 was the product of a mission-- to come up with a less expensive adaptation of the F75, while incorporating things we had learned meanwhile. Without "dumbing it down". Because the F70 was advertised for a lot less money than the F75, marketing dept. didn't quite dare to say how good the damn thing really was. Some of the secret sauce we put into the F70 eventually made its way into later revisions of the F75 group of machines, as well as into the Teknetics "Fratbros" series and most other new beeps introduced after the F70. As the top of the Fisher lineup, the F75 including its revisions got all the attention. That's how the F70 became a "sleeper". Guys like Mudpuppy will never have to wonder if they should have gotten an F75 instead. This is the same sort of explanation I just posted in "another forum" about the approx. $200 category. If you get a Eurotek Pro, you never have to wonder if you should have gotten something else. Get anything else, and you'll wonder if you should have gotten a Eurotek Pro instead. F70 owners never have to wonder if they should "upgrade" to an F75. --Dave J." Now, it is possible they removed a feature or two from the Patriot in order to justify the price differential, but with recent First Texas price decreases I would not be shocked if the F70 also comes down in price due to the just announced price decrease in the F75. Makes no sense to have the F75 at $599 and F70 at $649, reversing the order of the pricing just a short time ago. Regardless, keep an eye on the Patriot and the F70 to see what develops, but at $399 a Patriot is a machine that could even tempt me for a grab and go park machine. Teknetics was purchased for the premium name and its Fisher equivalent products have usually been more expensive for what are basically the same detectors. Gold Bug Pro versus G2 for instance or F19 versus G2+. These three models however are priced aggressively below their other FT counterpart models and appear to mark a shift in the Teknetics line to a lower price level. All this shifting of higher priced First Texas products into lower price points does smell an awful lot to me like new high end product coming soon. People do tend to equate price with value and First Texas is currently abandoning the higher price point area occupied by what are typically referred to as flagship detectors. I can't believe they will just cede that market segment to the competition so I hope we see some new high end product very soon. Perhaps the rumored CZX will finally appear!
  6. Something new for you Tesoro fans finally. Tesoro has released a new model called the Tesoro Mojave. Tesoro website link. Interesting little machine, specs out like a deluxe Tesoro Compadre in my opinion (12 kHz, ED 180 discrimination) and for a list price of only $279.00 (discounted to $251 on the internet). The Compadre is a remarkably good little metal detector for its price but was always limited by a hard wired coil and one knob operation. For you Compadre fans this might take it to the next level. The Mojave uses Epsilon series 5 pin coils and so a large number of inexpensive coil options already exist. Operating Frequency 12 kHz Searchcoil Type Round, Concentric Searchcoil Size 7" diameter Searchcoil Family Epsilon Cable Length Approx. 3' Audio Frequency Approx. 630 Hz Audio Output 1 ½" speaker and headphone jack Headphone Compatibility ¼" stereo plug Weight (may vary slightly) 2.2 lbs Battery Requirement One 9 Volt DC (alkaline) Battery Life (typical) 15 to 18 hours Optimum Temp.

  7. Good day did any of you on the otherside of the pond did try a Vista gold on gold nuggets?????25kgz I had a bit of success with it ,then I send it to be tested on hillfort (pounded spots..) RR
  8. Interesting - a dedicated gold machine by XP incorporating the new high frequency coil and marketed in Africa at a very low price, only $680 http://www.depardetector.com/product/depar/dpr-600/912/511 It certainly raises some questions. The first being, will we be able to buy this machine from XP dealers, or is it some sort of special deal for Depar? Personally I would be irritated by that were it to prove to be the case. I think many people here would rather buy this machine at a far lower price than buying a full blown DEUS and then having to pay even more to get the high frequency coil as an accessory. The video gives an idea how the high frequency coils may act. A big shocker for me - the elliptical version of the coil is said to operate at 20, 40, and 80 kHz! (See video). Is this what we will see in the high frequency elliptical for the DEUS? The round HF coil is said to operate at 15, 30, and 60 (56) kHz which is in line with what has been previously advertised.
  9. AussieMatt pointed out on another thread that lo and behold, the QED has appeared. I am not going to mess with all the long back history. Instead, it looks like we may finally have a new detector model from an independent designer after so many false starts over the years. If nothing happens to upset the cart reports should be coming in from Australia in the near future. Anyway, congrats to bugwhiskers and company. I truly do wish for it to go well for all involved. http://australianelectronicgoldprospectingforum.com/new-board-109/qed-update-8893/
  10. I wonder how it would do on Florida beaches? Very light weight, super hot on small stuff, can use Minelab compatible coils.
  11. Buried in the announcement of the new Minelab Gold Monster 1000 is the fact that it effectively replaces the Eureka Gold. From http://www.minelab.com/usa/customer-care/product-notices?article=305152 09 Feb 2017 Discontinued Product – Eureka Gold After almost 20 years of gold success, the Eureka Gold detector has been discontinued. As with any product discontinuation, Minelab will continue to provide technical support service. You can find archived product information on the Eureka Gold here. If you have any questions, please contact your regional Minelab office. And from http://www.minelab.com/usa/customer-care/product-notices/discontinued-products Discontinued Products As new technology is developed and improves upon the performance of our current product range, Minelab discontinues our older product models. These products are listed on this page alphabetical order for your reference. We aim to service and support all of our older products for as long as possible. All products are supported for a period of at least 7 years after they are discontinued. Unfortunately with some of these older detectors it becomes impossible to source the parts required for service work and so the detectors eventually become uneconomical to repair.
  12. What about this Steve? http://www.vallon.de/
  13. I came across this website, and their youtube video. They state the Pulse Induction detector discriminates even lead and aluminum, and it also shows an image. Anyone seen these? Dave
  14. Here is a 4 –18 khz variable frequency VLF metal detector that may find a niche in the States: the Rutus Alter 71. Ziggy Jinx Detector Testing (Facebook: Ziggy Jinx Metal Detecting) is currently testing the Rutus Alter 71 in the UK. MD-Hunter also has a write up (Rutus Alter 71 test. New 2016) which includes several non-translated videos. The Alter 71 was apparently released in the autumn of 2016 but apparently is not yet available in the US. I am not familiar with either the Rutus MD’s or of any US dealers. Non-verified & non-translated video(s) indicate the box may include both 11” DD and 9” concentric coils, control box and housing covers and a 6 cell AA battery pack similar to the Garrett AT series. Battery life is approximately 20 to 50 hours depending on the frequency settings; estimated price US $725 plus; the menu appears to allow you to toggle over to English. The battery door upper insert tabs may eventually break off with use. Ziggy Metal Detecting posted the following on another forum: November 16, 2016 The New Rutus Alter 71 [ Website here to show some pictureswww.rutus.com.pl] …“Some Information here on the Alter 71 I've gathered below. At the turn of October and November will release a new detector. The name "Alter 71" - from the Latin "other" and the number 71 represents the number of available frequencies. Alter 71 is probably the world's first metal detector continuously tunable as a function of frequency. The detector is tunable from 4.4 kHz to 18.4 kHz increments of 0.2 kHz - without the need to replace the probe. I know of no current market detector is not possible. The detector is equipped with a radio transmitter digital data allowing such cooperation. With handsets or "wireless headphone jack." Digital transmission has been specially designed for this purpose - does not introduce any delays. 6 hours of battery life "toes" depends on the frequency and ranges from 20 to 50 hours. The detector has the ability to work in a static mode, dynamic or so. mix - the dynamics of the "mixa" can go smoothly depending on the needs. Graphic display, ID - 120 points, discrimination classical and selective, chart depending on the phase of the signal, automatically tuning to the ground speed control filters ground in a very wide range, the possibility of programming your own sounds, ranges, speed, separation and many other features make the it is a detector at the world level. The detector has a completely new mechanical design and is lighter than our existing detectors over 200 g. For the detector probe will be available both DD and concentric. Regulatory elements: Discrimination tenderness Dyskrymincja selective 120 points Operating frequency of 4.4 kHz to 18.4 kHz jump 0.2 magnetic stones Response filters (groundwater) - 8 speeds to choose from Masking 7 levels The signal level leading Ton leading signal Sensitivity leading signal - regulation allowing for a smooth transition from pure dynamic work to "mix-a" Strengthening Audio - regulation allows to change the sound characteristics of a dynamic channel and switch it off completely (we obtain in this way the work of a purely static) Volume Tony - three sound profiles to search for coins, three to "relics, and three freely programmable by the user Wireless nature - off, Channel 1, Channel 2 Backlight - 29 adjustable levels Type of ID - true (depending on frequency), converted to 6kHz, converted to 12 kHz Hold time - adjustable display time information about an object on the LCD. Detector has 7 default programs: a deep, deep, large silver, basic, coins, fast, very fast. Factory programs offer a fairly wide cross-section of the possibility of the detector in search of various objects in different conditions. Each factory program can be modified to suit your needs - and the changes are saved when the power is turned off. In case the modifications do not meet user expectations - it is possible to reset each program to factory settings.” The Alter 71 target may be only coin and relic hunting. Provided the MD does not demonstrate a frequency preference, the higher frequencies up to 18.4khz puts this MD tin he small nugget range on ground within the VLF limits. Perhaps this will excite future development of a variable frequency MD with fixed steps with a 3kHz to 48khz range. Shelton recently posted that he is also testing the Rutus Alter 71 and provided the following link: http://www.rutus.com.pl/page/19/alter-71. Hopefully, he will provide future updates on his testing & review. For now I'm hanging on to the MLX705; other than wait and see; any thoughts on variable frequency VLF MD’s for coin, relics and nuggets?
  15. Hi steve and members, can the coils from the gold bug series be used on the go ldstrike, thanks all for your imput. lennie-downunder.
  16. Is there any usable difference with the Teknetics G2+ when used for nugget hunting?
  17. Here is a machine I have not heard of before: http://www.metaldetector.com/drs-ground-exper-metal-detector?awt_l=3I64Qc&awt_m=K4CvxdoyBVWfZf It looks interesting but does it really work? I haven't even heard of the company before. Anyone have any info on this? There are quite a few videos which I haven't watched yet - but will. Just thought I would throw it out there for discussion.
  18. I would like to know which appropriate and best all purposes detectors and especially for depth , I live in north Africa, a lot of treasure.. Many civilizations were here: romans, vandals, Berbers, Byzantines...and much more, I will be waiting your answers guys.
  19. Hello everybody, I am interested in buying a TITAN GER 400 for a sandy desert with stones area, Does anyone has one or has ever used one ? Please any advice or recommandation is most welcom, Gyo
  20. From http://www.trademarkia.com/xventure-86677796.html "On Monday, June 29, 2015, a U.S. federal trademark registration was filed for XVENTURE by White's Electronics, Inc., Sweet Home, OR 97386. The USPTO has given the XVENTURE trademark serial number of 86677796." A Russian site at http://md-arena.com/wiki/whites-xventure/ has very speculative information hinting at multi frequency, 11" DD coil, and 4 AA batteries. The fuzzed out picture is probably not the machine - I am guessing they just wanted a teaser so used a Teknetics G2 photo and blurred it. The whole specs thing could just be wild guesses so do not put much store in any if this except the trademark application, which usually means a new machine in the year following the application. Or no machine at all - not all trademarks get used.
  21. Hello all, Longtime lurker, first time poster as they say. I've been coin detecting for about 2.5 years and now want to try gold detecting. Although I consider myself a decent detectorist when it comes to coins, I have no experience detecting gold. I don't even know if there is gold in my area...but I'm going to give it my best shot to find out. That being said, I don't want to go out and buy a dedicated gold machine right now. I would like to try what I have, see if it looks promising and then maybe get a GoldBug II. I tested 6 of my 9 machines on small pieces of lead down to 0.2 grams and the Tejon gave the best air test results (as expected as it is the highest freq. machine I have). I was using the stock 8x9 concentric coil. My question is - what would be the best small nugget coil for the Tejon? My ground is 'hot' as my AT Pro normally ground balances at 94, so I think a double DD or 'widescan' would be best. I am looking at the 5.75" widescan and the 10" elliptical widescan. Would the 5.75" be significantly better than the 10" on small nuggets? Should I be looking at the NEL coils also? Thanks in advance for any insight or help you can give. I'm anxious to try my hand at gold detecting and want to get the best coil for the Tejon to give it a shot. Jon
  22. Deteknix first made their name with their XPointer pinpointer. The products are made in China and the company has a U.S. office in Covina, CA. The website is at http://www.deteknix.com/ The first detector by the company got a lot of notice prior to release based on photos showing a relatively simple and modern design. Key features were a straight shaft, light weight, built in rechargeable battery, built in wireless headphone capability, and supposedly waterproof to 3 meters. However, the new Deteknix Quest Pro got savaged pretty bad on release. http://www.dankowskidetectors.com/discussions/read.php?2,98160,98881 The brand was also discussed back in April on this forum at http://www.detectorprospector.com/forum/topic/1904-new-deteknix-metal-detectors/ Then Findmall set up a forum at http://www.findmall.com/list.php?106 for the new brand. it only has a few people posting but one caught my eye - George Kinsey, who goes by woodchiphustler. George has been around and I have found his opinions to be of value. I thought it interesting that despite early bad reports he seemed to not only like the units, but had interest in being a representative for the brand. My assumption is new brand/new model teething pains but otherwise looking good enough to get more than a passing glance from George. I can't say for sure having never been even near a Quest Pro. The main reason for this post is that the company plans a similar machine but aimed at gold prospectors - the Deteknix Quest Gold. It is to be a 19 kHz machine and except for the frequency appears to be a general purpose detector. There is no release date at this time for the Quest Gold or another planned model, the Quest Diver, a waterproof unit. The company does make a wireless headphone setup with a transmitter module you plug into any detector, and a receiver module that lets you use any headphone you want. Looks good on paper, but again some initial issues reported with lost signals, etc. I assume that will get sorted out. Anyway, no real reason for posting other than to keep people alerted to possible new prospecting detectors. I can't say that I personally have any real interest in yet another 19 kHz single frequency detector. There are too many now as it is, and no new one is going to do something that existing models can't do also when it comes to detecting gold nuggets. It really is just the design itself that is interesting more than what the machine can do that is interesting. That, and the Chinese finally making a credible attempt at entering the market by at least opening offices in the U.S. You might think this would mean more low price competition but the Quest Pro at $599 will not put much fear in the competition. The Quest Gold is rumored to be about $100 more than the Quest Pro. The Quest Pro was supposed to be waterproof to 3 meters. Some websites selling the unit still say it is, but the company website only says "All Terrain Structure Design" so I am not sure just how waterproof these units are. I think single frequency VLF is now at commodity stage with the number of new names producing models seemingly growing by the day. This can't go on forever and we are seeing some hints of a coming price war.
  23. Picked up a new White's Treasure Pro for my wife Carla. Very happy with the quality and simplicity of the unit. For 360.00 shipped you can't go wrong, it's light, has auto ground tracking or lock track, backlight display and a 10"DD coil and takes 2 AA batteries . I was playing with it yesterday and it is pretty impressive. Dime at 7" Quarter at 8" not an issue. And no how do I .......this again from Carla! Every ones happy.
  24. When I got into metal detecting in 1972 it was pretty simple. No discrimination, everything went beep, just dig it all up and see what you find. Advances came rapidly however, and manufacturers focused on making detectors that could eliminate trash to the highest degree possible while find coins. Coin detecting was the big market by far, as silver coins were still relatively common in parks and other locations. So the goal was to find a silver coin while ignoring everything else. Anything smaller than a dime was generally considered a trash target, so sensitivity to small items was actually not a good thing. Low frequency detectors that handled the ground well and ignored tiny trash items ruled the day. Most detectors ran around 6 - 8 khz. Then we got multi frequency, the first and most popular being the Fisher CZ detectors running at 5 khz and 15 khz. The desire there is not what most people think. Single frequency machines do not handle a combination of conductive and magnetic properties well at the same time, the classic place being a salt water beach with a little black sand in the beach sand. Two frequencies can be used to compare signals and reduce both the salt signal and the magnetic signal simultaneously more efficiently than single frequency machines. Multi frequency machines, in particular the Minelab BBS and FBS models, excel at accurate target identification. Again, sensitivity to tiny objects has not been the goal but instead accurate discrimination and ground elimination. The culmination came with notch discrimination and the ability to pick and choose specific target ranges to accept or reject. Always, when designing the detectors, when it came to borderline targets, the engineers focused on the idea that people hate digging trash. There is an ability on borderline targets to bias the detector response. You can find more good items if you let the machine do so but in return there will be more false positives and more trash dug. or you can really try and suppress trash signals, but some good targets get rejected with them. What I am talking about is the classic "iffy" targets. Ones that are extra deep, or next to a trash item, on edge, or which for various other reasons give mixed or broken signals. The machines got real efficient at cherry picking out the easy targets, and those started to disappear. All the online discussions and books started to focus on the need to dig those iffy targets to get results in places considered "hunted out". A detector running in all metal mode reports everything going on under the coil. Detectors running in discrimination modes do not but instead eliminate signals based on various criteria. The detector "sees" what it thinks is a trash target, and instead of a signal could be set to give no signal at all. The trash items just become invisible. A problem exists when a good item is directly under or next to a trash item that has been rejected. The detector, if set to ignore the trash item, also ignores the good item directly under the trash item. This is called target masking. But it gets a lot worse than that. The detector must ignore the trash target, then the circuit must reset, and then report the next item that comes along under the coil. This actually takes time, and that time frame is called the recovery time or recovery speed. The simple test for this is to put a nail next to a dime, and sweep the coil first over the nail and then the dime. If the dime is too close to the nail, it gets ignored along with the nail. If the detector has a very slow recovery speed, the nail and the dime can be inches apart and the dime is still eliminated! The faster the recovery time, the closer the dime can be to the nail and still have the dime signal. Many things can be learned doing this. First, sweep speed matters. Going slower gives the detector time to reset so if you sweep too fast, you miss the dime. Go slower, it can sound off. Second, direction matters. Dime next to nail, if coil is swept 90 degree across the nail, the dime gets missed. Turn and sweep along the length of the nail, and now the dime appears. This is why classic coin detecting skills recommends hunting a location from multiple directions. Coil size and type matters tremendously. Big coils have more chance of both the nail and dime being under the coil at once, and both being ignored. Small coils have a better chance of separating the targets. DD coils do better yet by narrowing the detection pattern. Tuning matters. If you set the detector to aggressively ignore all nails it is more likely to ignore the dime. If you set the discrimination to just barely reject the nail, even so far as letting it produce a pip or broken response, and now the dime may very well sound off also. In general you should only set to reject medium to small ferrous trash. Tuning out bolts will really mask about everything. Then people realized setting the nail to be silent and the coin to beep caused more masking than using two tones. A low tone for nails, and a high tone for dimes. Totally suppressing the nail is more likely to kill the signal from the dime. Letting tones flow from low to high keeps the audio circuit open and more likely to report the nail. All these tricks get combined, and so running with multiple tones, small coils, going slow, etc. all add up to more good finds being made. Now, certain machines have always excelled at this, in particular the Tesoro detectors and some older White's models. These were/are detectors with analog style single knob discrimination controls that could set a very fine point on where the discrimination point was between ferrous and non-ferrous. But as the new digital machines came online, we actually lost some of this capability because digital signals get broken down into small pieces for processing. Think old LP record versus early digital file recordings of music like MP3. An analog signal is continuous whereas a digital signal is a zillion little bits glued end to end, and just fast enough to sound continuous. It is like the frame rate on a movie file. It looks continuous to our eye but is actually distinct separate frames strung together. This digital type audio has been described as "gated audio", like a gate opening and closing, letting signals through. Analog type signals are described as "blended audio" or "bleedy signals" because the audio flows, blends, and bleeds together. With digital style audio the detector looks at a signal, decides if it is good or bad, assigns a tone (or no sound), then opens the gate and lets you hear it. Then it stops and looks at the next chunk, decides again, and opens the gate again before slamming it shut. Still with me? This is the biggie. It is this gated audio response and recovery times determined by processor speed that combine to mask targets. It gets worse. A dime right under a nail can be masked. The fun part is the deeper the dime is under the nail, the larger the area of masking is that occurs. If I sit where I am right now and hold my thumb up in front of my coffee cup, I can see the cup with my thumb in front of it. Now if I pull my thumb towards my eye and away from the cup, I can completely hide my coffee cup from view behind my thumb. Detectors actually have a similar "field of vision" effect going on, and recent surface trash can block out a lot or nearly all coins buried deeper down. Get the picture? You have a park where the surface inch or two is full of trash dropped the last thirty years. Under that are all those old silver coins you are looking for. But you have your detector set to reject all that surface trash and the coins get eliminated right along with it. There is far more silver lurking to be found than people realize. Still, all the way up to now, Fisher, Garrett, Minelab, and White's in particular have been cranking out detectors with the old "I do not want to dig trash" mindset at work, and the machines all have suffered from relatively slow recovery times and a bias against calling borderline targets good but instead calling them bad. And as a rule that has worked well enough for the U.S. market, especially because there were no alternatives and more importantly, people really had no idea what they were missing. VLF nugget detectors early on dealt with this, and the Gold Bug 2 and GMT both have ferrous id systems. However, their extreme sensitivity to tiny items and edge sensitivity to certain ferrous trash items like flat steel sections of rotted and disintegrated cans makes them impractical for most detecting outside of serious nugget hunting or perhaps micro jewelry detecting. Newer nugget machines like the Gold Bug Pro with a small coil up to now have been about as good as it gets for pulling non-ferrous targets out of ferrous trash and they are pretty darn good at it. That is why Gold Bug Pro variants like the Teknetics G2 and now the F19 and G2+ have been popular with and marketed to coin and relic hunters. The Garrett AT Gold is more popular with coin and relic hunters than nugget hunters for the same reasons. However, a detector renaissance of sorts has been taking place in Europe. They have thousands of years of ferrous trash in the ground and non-ferrous targets of all sorts scattered around in it. The very first thing that became obvious to them was that U.S. style discrimination schemes were pretty useless. The target types are too varied, so job one in Europe is to just dig all non-ferrous targets. The vast amount of trash in the ground also means recovery time is a large factor. The fields are huge and the hours long so light weight detectors are also favored. When I went to the UK for my hunt years ago I took a Fisher F75. At the time is was about the fastest swinging, fast recovery rate hot on small non-ferrous targets machine you could get in the U.S. The F75 and Tek T2 made a lot of their reputation in their ability to pull non-ferrous items out of ferrous trash. The reality is however that they still had some recovery time issues and a definite bias on borderline targets that cause non-ferrous items to be mis-identified as ferrous. The Europeans wanted something better. Some companies though simply ignored the market or figured what they had was good enough. Minelab in particular comes to mind. Where is their light weight, fast swinging, fast recovery detector? The X-Terra 705? Sorry, no. Tesoro has some good detectors but people really do want to see new detectors now and then, and they are content to just crank out twenty year old models. An opening was created, a vacuum that companies we never heard of decided to fill. Now, it just so happens all of this, everything I have described above, applies to looking for gold nuggets in trashy camp and other mining locations littered with ferrous targets. I have always kept an eye on what goes on in the relic hunting and European worlds because the needs and desires almost perfectly overlap with what nugget hunters need in trashy locations. And so a funny thing happened. Machines that work very well for nugget detecting started to appear in Europe. Names like the XP DEUS and Vista Gold entered my radar zone. One company, Nokta, suddenly appeared and targeted U.S. nugget hunters directly along with their sister company Makro. XP decided to get in on the game and added a Gold program to the DEUS. Most of this was actually driven more by the Africa market more than the U.S. market, as these days Africa is where the big bucks have been in nugget detector sales. The difference is that the DEUS in particular vastly improved the recovery time and it is now regarded as perhaps the best machine made for pulling non-ferrous targets out of ferrous trash. They did it using gated audio but with very fast and sophisticated audio processing. Nokta and Makro are doing something a bit different because their machines rely more on a circuit that almost perfectly duplicates the blended audio responses of old style analog machines but combined with digital discrimination. They also have the ability to sport much smaller coils than currently exist for the DEUS and so Nokta/Makro also have made inroads. Similar results can be obtained with either but with vastly different stylistic differences. The DEUS is the epitome of high tech wizardry, the Nokta/Makro units so far much more basic machines. DEUS is what White's could have done had they not been asleep at the wheel. All the pieces existed long ago with the XLT. And when I look at the Nokta/Makro detectors I see what could have been with Tesoro if they had not just stopped making new detectors. It is what it is however, and Euro style detectors are making waves and inroads into the U.S. markets, but almost as an afterthought as these companies target Europe and Africa. This long post all came about because I was out comparing a truck load of detectors again in the field, and the simple basic fact once again was right there before my very eyes. It all kind of boils down to two very broad classes of machines aimed at two very different end users. End user type one is common in the United States. The park or turf hunter. Park hunting requires sensitivity to outside factors, number one being that you just can't go crazy and dig holes everywhere. People like machines with high levels of accurate discrimination that deliver few false positives. In other words machines that focus on not digging a hole just to recover a trash item. The Minelab BBS and FBS machines like the Explorers and CTX 3030 are famous in this regard. They really are not the deepest detecting machines around by a long shot, but what they deliver is accurate discrimination results to depths beyond what most if any other machines deliver. I have a White's V3i that never really sees any use outside of parks because I like its incredible visual and audio discrimination customization features. The Euro machines do get criticism because while they are extremely good at telling ferrous from non-ferrous, they by design do allow for more false positives. A deep borderline coin in bad ground that my F75 will identify as ferrous a Euro machine will call good and have me dig it. What they really do not tell you is that the Euro machines do not tend to separate out different categories of non-ferrous targets very well, and so you find yourself digging all sorts of things like pull tabs because they end up sounding like a coin. And even a nail now and then. What I am trying to say with all this is that Euro style machines are really, really great for relic hunters and nugget hunters, or anyone who simply wants to recover all possible non-ferrous targets out of the middle of ferrous trash, or are willing to dig all non-ferrous targets in parks and other locations. What they really are not so great at is cherry picking certain types and categories of targets, and in general you will just dig more trash with the Euro machines than what I am calling the U.S. style machines even though that includes Minelab, and Australian company. Now you will get people who say they can cherry pick with a DEUS or FORS CoRe, and people who will say they can pull goodies out of thick ferrous trash with their Minelab Explorer, and of course that is true. I just think you are fighting the true underlying nature of the machines. This article is for the newer people out there who are confused by it all and looking for a little honest guidance. My advice boils down to this. If you simply want to dig all non-ferrous targets, machines made by Nokta, Makro, Tesoro, and XP excel at this task. If you really hate digging any trash at all and want to focus on certain targets only, like U.S. coins, then machines made by First Texas, Garrett, Minelab, and White's tend to focus more on what I would call "turf hunting" or hunting parks, schoolyards, etc where a high degree of discrimination is paramount to reduce needless digging. There are of course other companies but I have to keep things limited to the larger and more visible ones because things are already too complicated as it is. No matter which detector you use however, even the best cannot change the basic facts of target masking. There is stuff out there hidden under trash targets, and the only way to find those items is to remove the trash item first. The trashier the site, the more likely there are good items hidden away waiting to be found. There is no such thing as recovery time or target masking in all metal mode. In places where high value items are very likely to exist, nothing can be done but to dig it all if you want to be sure and not miss that once in a lifetime find.
  25. Is it ok if I make a new thread about the White's DR-PRO? If not please delete. Figured people might want to discuss this new product from White's Electronics. Will be releasing the announce video at 1pm PST today (just got approval to do so). I'll post a link then for all to see.
