  1. I’ll post link here. Folks can comment if they wish. Saves me time by not posting in detail on all forums. I like this forum very much. Hope I am not breaking rules here or am not upsetting anyone. http://www.dankowskidetectors.com/discussions/read.php?2,173272

  3. Hello Guys, I'm new on this forum and like Alexandre Tartar, I live in north of France. I was a young prospector in the 90's and asked my father (electronic engineer with good knowledge in magnetic field theory) to build a PI to hunt the beaches. So we have made, in a few months, an home-made PI metal detector 25 years ago, based on the technology of the old White's Surfmaster PI (mono coil). I remember the use of FETs (Field Effects Transistors to make 200 volts pulses). It worked, but unfortunately, my father was afraid by a so powerful magnetic fields and has continued his research on VLF detectors, until today ! After this short presentation, here's my question : Is the Impulse AQ a bipolar detector ? Le Jag has explained us on the french forum "detecteur.net" this technology developped by Alexandre : Positive and Negative pulse are alternatively sent. The positive one light the gold ring but magnetize the soil. The negative one demagnetize the soil. What about it ?
  4. Show simple targets you swore were gold. These were 12" inches plus in depth (all lead)....... Found with a borrowed GPX 4500
  5. HOW MAKE A SERIOUS COMPARATIVE TESTS PROCEDURE First rule Blind tests are mandatory to be serious. Second rule if you do not agree refer to rule number 1 😊 The purpose of this playground, and not to take into account the feeling of the prospector. It is too easy for a participant to indicate that he is correctly detecting the target. But in general he does not detect it or he thinks to detect it. It often detects a ground effect. During our long experience and our meetings with prospectors at the beach, we realized that the prospector was often influenced by the pride placed in his detector. This is why we have implemented this drastic and non-falsifiable comparative tests procedure. Of course for this test you have to be 2 people. A person who hides targets and a person who tries to find them. The depth tests can be done simultaneously. It is obvious that here are static tests. The reality is even more difficult! See for yourself the catastrophic results .... Document here : ******************************* https://www.casimages.com/f/qyqU0eUlCSb ******************************* COMPARATIVE TESTS PROCEDURE.pdf
  6. A few afternoons back I went out to a local beach to do my normal searching. It has been a time of few waves and even fewer targets. Everyone hears this from me quite often but I've heard it from other detectorists as well. So, you relax, go slow and just enjoy the beach. A bit down from me I saw a group along the blanket line and there was something different. There was a little kid (older than mine) about 5 or so swinging a metal detector. It had a kinda orange coil and the kid just was playing with it a bit and then running around with the other kids. I decided to go up with my 800 in hand and have a little chat with him and maybe 'show' him how to find things. By the time I got up to where he was he was out near the water and the only one still around was his dad and his dad's friend or brother. We started up a bit of a chat and they said they had bought the detector off of Amazon for $60. I didn't recognize it but it was giving my 800 an EMI fit so I went to a different channel. I told them what I had in mind (quarter in hand) and they called the little boy over. I wish I had taken a picture of the detector but it was a short arm, adjustable with compression fittings, concentric coil detector of a brand I didn't catch. It had a screen that was discriminating and it did 'find' the planted quarter which the kid liked but didn't have that much interest in it. One of the really interesting parts of the story was the friend. He told me it was an Amazon purchase and thought that $60 should make it a very good detector. They didn't really have a clue. They asked me about mine and I told them and I could see their jaws drop a bit on now knowing that 'pros' like me were out with detectors from $500 to $900! It was way out side of their conception so they asked me what did I think of their detector. I didn't really pick it up but I told them there are these new little detectors that could be better than a lot of the detectors just 5 to 8 years old that sold for much, much higher prices. This is part of the new purchaser and market for the detector companies which provide higher end products like Minelab. It is a new reality of buyer and probably the reason for their low end detectors. When I came back and searched Amazon looking for this $60 detector I was flooded with many, many detectors from companies unknown. Minelab is not on Amazon it seems and many other searches for the average buyer. Some of you here see some advertising on this forum for the best metal detectors. I started a thread about it a couple of weeks back. One thing I did happen across when looking for the metal detectors were a few 'board detectors.' These were complete metal detectors on a circuit board that sell for less than $5.00! It becomes more clear that these detector circuit boards placed in a molded plastic handle become the brains for a $50.00 detector that wholesales for maybe $26. Components are cheap. Marketing and R&D are expensive! I didn't find much on the beach that day but I brightened the face of a little kid and I got a good story.
  7. The GB knob on my Tejon is super loose now after the tons of hours I put on it and I get a little waver in the threshold. Trying to find who sells damping grease in really small quantities as the stuff is horribly expensive. Mcmaster has some at $111 + shipping, Amazon has some in the $30 range and all more expensive than the potentiometer itself. I could replace it but rather not start soldering in parts if I don't have to.
  8. Hey everyone, Just curious, has anyone tried lowering the tone break T1 to negative numbers or all the way down to -9 on your hunts? Is it worth it, did anything good come out? Or is it just a recipe for headache? Reason being, I was playing yesterday with the coil and found an old button that is clearly non-ferrous, but gives negative TID in multi-frequency and positive/negative on some single freqs. Thank you
  9. The art of detection shares common issues whether it be audio, optical, rf or electromagnetic. Some of the common issues are: A: Sensitivity B. Noise C. False signals and also the problems that filtering or mixing creates in trying to solve the above issues. A radar detector faces many of the same problems as a metal detector, and has up until this point in time used similar techniques to provide solutions. A radar detector manufacturer named Radenso has now applied AI to solving these issues. And some of their methodology could have applications in metal detecting. They are taking signal samples to identify good and bad targets and feeding them to a Super Computer, that then creates a signature which is programmed into the radar detector. So the super computer does the heavy lifting creating a library, and allowing the processor in the detector to simply do a lookup from a library. Some terms for those not familiar to aid in watching the videos: CW = continuous wave similar to a signal from a VLF metal detector BSM = Blind Spot Monitor are radar based collision and lane change units which emit radar and drive radar detector users crazy(think bottlecaps). Door Openers = Equal microwave(radar) motion detectors to open the automatic doors at retail stores etc https://www.vortexradar.com/2019/11/radenso-introduces-artificial-intelligence-in-radar-detectors/
  10. I am looking for some objective non-partisan opinions on what detectors are in use right now. I am seriously not interested in people promoting their favorite brand but just hoping for some honest observations. At your club what are the most prevalent brands and models you are seeing? Same thing at the hunts. What are the top two or three models you are seeing? My last couple trips to the UK it was simple. Now these are groups comprised not of locals, but visitors from the U.S. I’d say 95% were swinging either a XP Deus or Minelab Equinox, plus a few CTX 3030. That seriously was about it. In my circle of the serious prospectors I know it’s pretty much a Minelab PI/GPZ world. For VLF prospecting units lots of Gold Bugs, Gold Monsters, and White’s Goldmasters/MXTs. Garrett AT Golds are pretty rare. But what about general coin and relic across the U.S.? Not the serious forum types but the folks at the clubs and hunts. I’m guessing some regional preferences, and I’d have to guess Garrett is still big with many club type hunters going by YouTube activity. But I honestly don’t know what the masses are using and thought you all might enlighten me on that? This is really nothing other then pure curiosity on my part. Thanks in advance for any comments.
  11. Well it’s official. The Garrett GTI 2500, the flagship of the Garrett metal detector lineup, was over 20 years old in 2019. The GTI 2500 was introduced in 1999. Twenty years is an awfully long time in technology land, and I’d say it’s well past time for Garrett to do something about that. What would you like to see from Garrett in 2020?

  12. Will 2020 be the year of the cliche product? Will we see products capitalizing on the 'better vision' theme? Have you already seen them? haha 😋 What marketing slogan would you use for a new detector, coil, pointer, pick, pan, 4x4, etc., etc. ??? Here are a couple that come to mind ... White's Detectors ... clearly Better in 2020! Everyone will have 2020 nugget vision with the new Minelab ... New in 2020, glasses for your detector ... get our clear boost signal enhancer.
  13. Since I'm down and out with a broken ankle for a few weeks and have plenty of time on my hands. I decided to do a EX2 chest mount mod that I saw on You-Tube by IDX Monster, thank you sir for paving the way!! I have a bum shoulder that needs to be rebuilt next year, I needed to adapt my machine to extend my hunting time until then. I used a Teknetics S-rod for the stock 11" coil and a White's MX5 S-rod for the 8" coil. I'll be using a Go-Pro chesty to mount the control head and I bought a 3' extension cable to connect the control to the coil. I cut the battery housing from the handle, but, I have a more compact and lighter battery pack on the way. I ordered a 1/4" stereo headphone jack from Amazon and will run my phone cord under my shirt to keep it from getting in the way. This set-up is as light as feather to swing and I can't wait to heal up and take it on it's maiden voyage.
  14. Book Excerpt: 14/ Modulation Modulated audio acts to reduce noise and response irregularity in a high gain audio platform. That’s a lot to manage. Modulation defines each tone and makes all signals sound better and more the same. This also represents an artificial, distorting influence--a kind of audio “no-man’s-land”where small objects sound bigger and large targets are “clipped down.” This is especially true in the “tone ID” modes. For the operator, modulation makes it harder to tell a deep faint response from a small surface one. In conjunction with Gain, modulation makes small responses more distracting--sounding fuller and more solid. Modulation also makes tiny mineral, seabed or black sand variations jump way up to sound more like good signals. Determining a response’s shape and distance from the coil are also harder. What you have is a digital representation of ground and targets--more of a measure of the relative differences between the two than an actual metal object reading. Another consequence of this is that big targets sound smaller--cans--sunglasses--all are modulated to often sound like they are (more) coin or jewelry-sized. I’ve had some particularly frustrating deep-water hunts with the Equinox giving tantalizing small indications on what turned out to be super-deep “rotten glasses.” This operating characteristic can be confusing for new hunters. This, in particular is an Equinox operating characteristic that is easier to make sense of and manage with some solid, basic instruction. For anyone--the “trade-offs” that derive from the Equinox’s heavily modulated signal are its most frustrating feature. 1/ The first, most basic method of managing a heavily modulated signal is to turn the volume down. Even going to “24” or “23” makes a huge difference. This makes for more audio distinction between weak and strong signals. Many CTX hunters discovered this after becoming frustrated with that detector’s tendency to bring up tiny conductors. With its high frequency weighting on several of the pre-set modes this is more so of the Equinox. While many of the underwater headphones that are available are quiet to begin with and don’t allow much of a margin for reduced volume--the stock 800 series wireless set do. 2/ Focus upon the more solid signals. This is a critical Equinox skill in any context. Even as a pulse hunter who has experience with fast Delay machines that hit running shoe eyelets loud and clear--the Equinox was initially exasperating to use for me because of these modulation-boosted targets. While I see some patient hunters getting good results “micro gold” hunting this is at highly specific types of locations. The solution is simple basics. Rather than digging endless tiny part-responses--use Pinpoint to check for solidity--and do a quick angled pass to see the consistency. (See “Pinpoint” below). With practice these small conductors will become more obvious in Discriminate as well. This is the way to offset the distortion of a modulated signal--but still get its benefits. This is where the above mentioned “correlation” comes in--looking for “sets” of target characteristics to double check what the audio is telling you. Even when examining tiny “earring-sized” sounds it’s possible to screen for solid targets and use this as a basis for gathering a full target profile. Each signal feature (size, strength, solidity, position in strata…) should confirm the others. The depth meter is also a good tool for offsetting the distortion of modulated audio. Signal depth and signal strength should be “in keeping.” (More on this type of method below). Modulation is more active in the Tone (break) ID modes (especially “5 Tone)” so using the more fluid “50 Tone” or just “Pinpoint” are good ways to compensate. One reason that many hunters have trouble adjusting to the Equinox is that again, this high Gain / high frequency / modulation combination reduces your ability to judge how far from the coil something is. This in turn throws off your sizing. The number of hunters I see on “YouTube” videos trying to ignore these simple target testing basics is laughable--with many trying to pass off this as some cool “dig everything” ethos. Again--not “everything” is “anything” and a machine like the Equinox will tell you when not to dig sometimes--loud and clear.

  15. I noticed a lot of the older threads had lost their attached "tags", probably due to an update somewhere along the way. I've been spending hours today working from the oldest threads forward retagging everything and also moving some threads to other more appropriate forums. Seems to be mostly 2016 and before stuff. Whatever, housekeeping. It has been interesting in seeing the large number of "gold found" threads created back in the 2015 - 2016 time frame especially. We had the double whammy of the SDC 2300 followed by the GPZ 7000. Both machines are good at finding gold missed by the earlier Minelab PI models. This created a mini gold rush in two ways. First, the machines actually do target gold the other models were weak on so they did find gold the others could not. But a large portion of it was simply new machines giving people confidence to go back and hunt old areas once again. Often there is knowledge from prior hunting that allows a focus on where the gold is known to be. Gold was also therefore found the earlier machines could have found but that was simply missed by earlier hunters. Well, four years on now and things have slowed down a lot. It's mostly the old die-hards still at it, but lots of people that were active back in 2015 have gone quiet. I'm sure I know why. There were many old "dead" patches I hit with the GPZ 7000 that came alive again. The problem now is it is back to eking out smaller and smaller returns for time spent. The sad fact is there is only so much readily available ground out there and we are once again hitting that depleted stage with existing technology. This can't go on forever as every nugget found is one less to find and they are not growing back. We need a new toy soon or things are going to get pretty quiet. Compared to 2015 they already are. We've seen this story many times before going back to when Minelab PI took over from VLF, and gold VLF machines taking over from the coin detectors prior to that. Forum threads tagged "gold found"
  16. Forget VLF and PI: here comes the BastardXWave! Fully utilizing the latest XWave technology the BastardXWave detector punches far deeper than any other detector ever invented in the long history of detector prospecting, both on land and sea (it’s submersible to -801 metres). With this detector there is absolutely no need to dig for anything except your favourite metals, coins, jewellery or relics. Its vastly superior XWave detecting technology ignores all crap, including bottle tops, aluminium foil, nails or lead sinkers/birdshot (and everything else you don’t want to dig). It’s as easy as flipping the dial to the ‘IGNORE ALL CRAP’ mode and the BastardXWave does the rest. In the IAC mode the user has a ‘Voice Assist’ option where a very seductive female voice suggests you dig a bit further to the left or right to hit the hot spot. Obviously, by dialling the ‘DIG ALL CRAP’ mode you’ll be digging crap all day long. Although any serious detector prospector will scoff at the DAC mode, it does keep newbies and kiddies entertained for days (if not weeks). Once you’ve flipped to the desired mode, you’ll need to tell the BastardXWave what it is you’re looking for. If you only want to find gold just push the ‘FIND GOLD YOU BASTARD’ button in the IAC mode. In the FGYB setting the BastardXWave will immediately find gold no matter how tiny or deep in the hottest ground, just wave the detector in the general direction of the area you want to search (you don’t even have to leave your car, just make sure you wind down the windows). You can rest assured that in the FGYB setting all you’ll be digging for is gold, in fact you’ll find so much of the yellow stuff that you’ll be able to pay someone else to do the digging for you. It’s the same for all other metals (such as silver, copper, lead or zinc), just hit the right button whilst in the IAC mode and become an instant billionaire! If you have the urge to find only alloys, just hit the ‘FIND ALLOYS YOU BASTARD’ button in the IAC mode and the BastardXWave will hone in on any alloy humankind and aliens have ever created. Here the ‘Voice Assist’ girl tells relic hunters whether they are digging for an ancient pewter goblet or a wrought iron spoon. In fact, the seductive voice easily identifies the age the relic was created, for example during the Victorian Age or even the Bronze or Iron Ages (if some hunter-gatherer smelted it, the BastardXWave will find it!). Besides analysing age and metal combinations, the detector also shows the condition and current market value of any relic it has spotted, this is of great value in deciding if your lackey digs or not. To find any coins of any country no matter how old just push the ‘FIND COINS YOU BASTARD’ button in the IAC mode and away you go. Just walk around any public place (parks, sporting grounds, beaches etc.) with the FCYB setting turned on and the BastardXWave will alert you to the nearest coins in the vicinity, no matter how deep or how salty or hot the ground. This handy feature means there is no need to swing the detector until it plays ‘We’re in the money’ (a very appropriate ditty by the ‘Gold Diggers'). Likewise, simply pushing the ‘FIND JEWELRY YOU BASTARD’ button does the same thing for any piece of jewellery you can think of. In the FJYB setting the detector will play George Jones and Tammy Wynette’s ‘Golden Ring’ before you need to start swinging. The BastardXWave is also extremely sensitive to diamonds and other high-value gemstones; in the ‘FIND GEMS YOU BASTARD’ setting it’ll play Marilyn Monroe’s ‘Diamonds are a girl's best friend’ as soon as it shoots your latest stone-clad crown. Finding rare earth metals (including cerium, dysprosium, erbium, europium, gadolinium, holmium, lanthanum, lutetium, neodymium, praseodymium, promethium, samarium, scandium, terbium, thulium, ytterbium or yttrium) is also simplicity itself. Just flip the dial to IAC mode and hit the ‘FIND RARE EARTHS YOU BASTARD’ button. This will promptly find all of the rare earth metal thus far discovered (and even those that haven’t) down to extreme depths very close to the Earth’s core (some might be a bit too deep to dig). As with all the other settings, the FREYB setting can be tuned to the maximum depth you feel like digging; for example, your average detector prospector will be very happy with the 1-5 metres range whilst global mining companies use the BastardXWave to find tiny deposits of rare earth metals several kilometres deep. Likewise, finding meteorites of any size or composition is as easy as pushing the ‘FIND METEORITES YOU BASTARD’ button whilst in the IAC mode. This will instantly link the detector to satellites which beam down the latest lat/long coordinates of impact zones near you and pinpoint the nearest fragments. The BastardXWave also accurately predicts where and when the next meteorite strike will occur; another very handy feature which besides finding meteorites also allows you to take cover at just the right time. The BastardXWave’s manufacturer is currently working on ‘ERADICATE POVERTY’ and ‘STOP CLIMATE CHANGE’ settings. These awesome new settings will be available in latter models (including the BastardXWave Pro, BastardXWave Lite and BastardXWave Drone). Disclaimer: Due to deep fears of Chinese industrial espionage, the manufacturer will never release any photographs or technical information on how the BastardXWave works. None the less, you can still order one by privately contacting the manufacturer to haggle a fair price. The manufacturer will only sell the BastardXWaves on the condition that the buyer promises not to brag too much about how much money they’re making from this detector. Because the BastardXWave is so undeniably unique, the manufacturer regrets that there will be no refund after it’s been mailed to the buyer. Nor is there any form of warranty or spare parts. Just one left! Buy it now before it’s sold out!
  17. From Wikipedia: "A long-range locator is a class of fraudulent devices purported to be a type of metal detector, supposedly able to detect a variety of substances, including gold, drugs and explosives; most are said to operate on a principle of resonance with the material being detected." There is more at the link, but "a class of fraudulent devices" says it all as far as I am concerned. I just wanted to post this so people can find it in the search results in case they are looking. For me these devices have always failed the most basic test... the experience of hundreds of thousands of prospectors and treasure hunters around the world. Treasure hunters and gold prospectors will give anything a try that might work, no matter how crazy it seems. If it works, the use soon spreads to other prospectors. You can Google genuine successful results for regular metal detectors all day long. The internet is full of successful people using normal metal detectors to make great finds. Except for a few obvious promotionals, the success stories of people using LRL devices are glaringly absent. All excuses for why this is so flies in the face of the simple common sense answer - they don't work. In almost 50 years of metal detecting and prospecting I have met a lot of successful people, and none of them got that way by relying on a long range locator. Part two of the common sense test is if they did work, there would be at least a few users of these devices that would be fabulously rich. The few I have met are anything but... just the opposite. Again, excuses made about why these rich LRL users are invisible fly in the face of common sense. As if we are not a country that brags about every tiny thing we can think of! The only people getting rich are the people selling these devices. I personally refuse to purchase anything from a company selling long range locators. It says something about the management of the company that makes me prefer to do business elsewhere. More at Geotech

  20. Hi all If I'm using a vlf/lf that is over 40khz, is there any benefit to getting a 2nd machine that runs under 40 kHz when prospecting? Assume PI is not possible at the moment. Does a sub 40 bring anything special to the table? I'm a beginner so just curious Thanks
  21. As much as I enjoy using the gm1000, especially in the auto modes, I can see how a Gold Monster PI machine would be popular. Grab and go, auto modes, under 5 lbs. Sounds great to me???
  22. Not sure this is a topic for this forum, but this is where I see a large number of technically adept folks posting so I'm going to try (also the folks who are talking about x-coils on another forum). Has anyone had detecting experience around these 5G installations being rushed out everywhere across the world? It will be interesting to see what levels of interference are generated by this emerging technology. I personally am very much against it's roll-out because there are no deep studies that portray it as a safe-for-living-things technology, in fact the opposite seems to be true, but that aspect is probably not a topic for this website.
  23. I welcome! Minelab is a hybrid MDS-10 Minelab multi-frequency metal detector and Ultra WideBand pulse radar from Chemring. In the summer of 2019, the Minelab MDS-10 project (version 2.0) was adapted to search for historical finds. For what I bought, for what I sell ( https://md-arena.com/sekretnyj-proekt-minelab-gibrid-detektor-georadar-novinka-2019/ ). Target sizes include coins and jewelry. Practical tests confirmed the effectiveness of the technology. In Russia expected that the novelty will be presented at the copy slate Detectival 2019. But alas... Does anyone know when? IMHO Minelab should enter the market of such devices.It is impossible to give the market all the time to LORENZ, MAKRO Detectors, Nokta, with ichony georadars. With respect.
  24. Hello everyone .. I wonder if there anyone who uses a 3D metal detector to locate gold deposits @ around 15 to 20 feet deep... I have heard of larger nuggets of 1 and 2 pounds in size and gold deposits with 300 grams in a bucket of dirt being found in the river banks. Could a GPX with the New 30" coil could reach a 1 or. 2 pound nugget @ 4 feet deep... Im not interested in the finer gold just the bigger nuggets or a large concentrate of gold ..
  25. I would like to see what any of you have created as far as displaying your metal detectors at home. I'm looking for creative ideas to make a home display myself. I'm entertaining many ideas from open to closed displays, even using Curio cabinets. To be clear, I'm looking for ways to display machines primarily, which could be mixed with finds as well.
