Is this the future of detecting?  I think so.

Take a set of data points and process them (just as we do with our brains) and voila!  It doesn't have to be magic when you have good science to make it repeatable.  

Watch out missed nuggets!

Currently, a type of software based on a machine-learning algorithm called deep learning has been shown to be effective at removing the blurriness or noise in images. These algorithms can be visualized as consisting of many interconnected layers or processing steps that take in a low-resolution input image and generate a high-resolution output image.

Wow! Imagine what kind of cost you'll be looking at to have a processor that intelligent in a detector!!! 

Worth it.

Amazing.

Data points can be in any form.  They can be sound, light, magnetic, etc.  If you already have a sensitive collector of data this algorithm will make it see better.

Now you have to bring these ideas into market perspective.  When would Minelab obsolete all of its detectors in favor of a technology this powerful?  Not any time soon and by that time many of our nugget patches will be nearly barren but that makes it easier to find a few targets rather than a few targets in a lot of trash.  Everyone can imagine ... 

Steve is right.  It takes innovation a while to be incorporated.  Many of us here grew up watching the 'Space Race' and were told that we would benefit from all the money spent.  We have.

Chet has probably seen much more than the rest of us and he can't tell ... even after he has been retired.

This is a type of a neural net AI. They can be extremely versatile. My roomate back in college was doing his PhD thesis on them. They can be open source and put onto a chip and set to learn and solve an almost infinite number of problems. Sometimes the most efficient solutions they come up with make no sense to humans we almost certainly wouldn't come up with them ourselves in that way.

To understand just how versatile they are, recently a different type which was named AlphaZero was introduced to chess. Starting from nothing but the basic rules of the game, it did nothing except played games against itself and within 24 hours it was strong enough to beat the best human chess player in the world. In 3 days it figured out new ways to play the game and beat the strongest computer chess program humans had written in all the decades we've had computers. Now there is talk about pointing this very same AI to the basic rules of physics and biology to see what it comes up with.

These AI's can easily be put on a chip that are affordable (like $20), especially smaller and more specific ones. Though the really powerful ones still run on supercomputers.

I've been trying say for well over a decade now that there are tons of places that detectors could improve with modern techology and a company that simply is willing to pursue stuff that is at this point, "old news" in the tech world. That's ignoring completely relatively novel stuff like AI which alone could be a new frontier.

It's hard to really put it in perspective how far behind the tech curve detector companies are compared to really any other segment. They are dinosaurs. Even some of the Minelab stuff.

The bottleneck may be the amount of processing power needed.  Steve H. mentions the speed at which that can be minitiarized and made cost effective (calculator analogy) but it does depend upon demand.  Dedicated processors (as opposed to general purpose supercomputers as was used for the Google AlphaZero work Jason mentions) will help for the simplification/miniturization, but can that be simply borrowed from another more in-demand application?

CCD cameras are another example of progress.  They used to be mega-expensive for modest (in today's world) 1 megapixel packages.  Now every cellphone has many thousands of times better resolution and it comes effectively for free(?) as part of the deal.  But again, the demand for digital cameras (the intermediate evolutionary step) was high.  Metal detectors?  Not so much.  That's why it will need to piggy-back off of an in-demand application.  But for sure the potential is there.

AlphaZero has an open source equivalent called LeelaZero. Leela can run off a laptop computer ok. 

A Raspberry PI 4 at $55 is a full computer, with negligible weight gain, in which you can run an AI plus interface sensors (like a metal detector coil). It has a 64 bit quad core CPU, wireless, USB 3, etc. 

Shows just how cheap powerful electronics can be built today. There are competitors and various other peripheral devices built by essentially garage based, hobby companies for about the same price. A startup detector company could compete if they had good, highly skilled engineers and scientists, and thought outside the box.

AI aside, just looking at the world of stuff you can do with the massive amount of cheap computing power avaiable to even hobbyists today - Minelab appears to be the only company looking at software solutions, based on their patents I've read so far. So again, the rest of the pack will find themselves left in the dust with nothing but a patent wall to contend with when they finally wake up to modern technology in another 10 or 15 years.

Jasong,

This is the stuff I thought might be on the chips in the Equinox and it could be on the 6000 if they wanted it but then what would they do for the next generation detectors?

Maybe Geo Sense is a marketing name for an algorithm!

I think the physical detecting principle would have to be changed or enhanced somewhat for this to really change the treasure hunting game.  I don’t think magnetic induction principles alone can achieve huge gains at this point even with AI applied.  A combination of induction balance or PI for conductive metal detection combined with compact/low power/high resolution Ground Penetrating Radar would be killer for deep, larger cross-section targets.  Magnetic induction would still be needed and would probably dominate for detection of small targets and tiny natural gold.  

Also use of AI and Augmented Reality combined with ultra precise ground mapping would also be a useful tool.  Imagine donning a pair of Augmented Reality glasses that could enable you to see where your coil has actually been to ensure complete ground coverage at a site, visual target logging (to ID target density/concentration).  I mean how many targets are not recovered simply because you didn’t get the coil over the target and not due to an inherent limitation of the machine.  The ultimate objective would be finally giving you the “X Ray” vision ability to actually peer into the ground and “see” buried targets in situ and in real time and without a semi-trailer of electronics needed to achieve that goal.

      I was out yesterday and remembered that the Gold Modes (I use Gold 1, if that matters) can be used to investigate iffy targets.  Then I had a thought when I noticed a lot of ferrous hits per swing (likely nails) while searching in Park 1 (no notching/discrimination), gain of 24, Recovery Speed = 4, Iron Bias F2=0 -- I switched over to Gold 1 and the target rate per swing increased dramatically, something like a factor of two!  (Note:  there aren't hot rocks in this location and I checked that ground balance was correct.  I'm pretty sure these are bits of iron such as nails or pieces of wire.)  I also checked in Park 1, 4 kHz since there have been reports here that this sometimes eliminates iron grunts.  That wasn't the case.
      This got me thinking about what the Gold modes are, or at least how they are different from the other modes.  In limited testing (@40 kHz) I've found that they can detect coins deeper (or maybe 'farther from the coil' is a better description) than the other modes.
      Once again having to deal with the confusing (non-standard) nomenclature, it seems that the Equinox Gold modes act & perform similarly to the "all metal" modes of other manufacturers' detectors such as the Fisher F75.  (For example, the only tone option is Voltage Controlled Oscillator = VCO.)  Dave Johnson has used multiple terms to describe that kind of mode, including 'single filter' (see F75 user manual).  In other words, it's as close to a raw signal as you can get if using motion to maintain stability.  So that leads to the question:   is this all the Equinox is doing in Gold Mode -- using the minimal amount of signal processing to keep the response stable?
      I can think of one filtering option available in the Gold modes which isn't present on traditional all-metal modes of other detectors -- discrimination/notching.  But even for that, the F75 all metal mode has digital target ID readout so something is going on there, although in that case possibly in parallel.

      I’m a newbie and saving up to buy my 1st  metal detector. Meanwhile I’m rockhounding a lot.
       
      I’m curious if folks have successfully applied portable ground penetrating radar (or other portable detecting devices) to predict likely location of crystal pockets in the hard rock, like in dolomite (for locating pockets of Herkimer Diamonds) or in granitic pegmatite (for locating pockets of gem tourmaline crystals) ? Any pointers would be appreciated.
    • By JCR
      Has anyone done a comparison of the mineralization readouts of various brand detectors on the same ground? I know Fisher F75 is considered a standard. I would like to be able to compare my NM Anfibio readings to other detectorist's ground conditions. F75, Deus etc. Also what GB settings others consider mild----hot ground.

      So I thought I would throw a spanner into the discussion. Here goes.
      We have heard of the double D coils what about a triple D coil. Well that outside my knowledge but let look at a quad D coil the oldest ground balancing coil. Have a look at these links.

      Metal detectors aren’t just for hunting for gold. They’re also enormously useful tools for law enforcement. And yet, while most police departments have metal detectors on hand for crime scene investigation, far fewer have trained and qualified officers who know how to use them correctly. But when deployed properly, metal detectors can be a game-changer when it comes to effectively investigating a crime scene, uncovering evidence that might otherwise go detected while at the same time preserving a crime scene from disturbance.
      The evidence of metal detectors’ effectiveness is conclusive: A study published in Law and Order found that “Automatic Very Low Frequency (VLF) ground canceling metal detectors have proven to be the best all-around choice for ground (land) searches in law enforcement applications.” This was attributed to “their ease of use and sensitivity.”
      The use of metal detectors at crime scene investigations goes far back into history. In fact, a metal detector was used to uncover the round that was used in the assassination of President James Garfield.
      Safety is another factor when it comes to using metal detectors. To use an obvious example, consider a hypodermic needle in the middle of a pile of leaves. A metal detector can help an officer to discover such evidence without him having to root around in the leaves risking injury — or worse.
      When searching for weapons in a house, you can program a metal detector to ensure that it doesn’t read common objects in a wall or a floor. This makes it easier to find objects when they have been hidden with great care by a suspect.
      There are tons of reasons for police departments to have metal detectors and use them with vigor. What’s more, it’s probably less expensive and easier to both purchase and train than you probably think.
      Use It Or Lose It: Budgeting for a Metal Detector
      We spoke to former police officer Dave Bachert. Dave has over 20 years of experience as a police officer, having served in Allentown, Pennsylvania as the Supervisor of the Evidence Unit. While serving in that capacity, he went out and purchased a metal detector for his department. He notes that one of the first things he mentions to police officers with department purchasing power is that their budgets are, more often than not, “use it or lose it.”
      This means that the unspent budget will not rollover to the next year. And while many police departments find things to spend budget money on that are arguably frivolous, many don’t have metal detectors. So if there’s money sitting around at the end of the year — or even at the beginning — a metal detector is a wise investment that will not only uncover evidence that might otherwise go unseen but will also speed up the process of combing a crime scene investigation for evidence.
      Without Proper Training, Your Metal Detector Is a Paperweight
      Part of the reason that many departments don’t buy a metal detector or don’t use it is because they find the equipment to be intimidating. They might even have one, but no one wants to use it because they think it’s going to be too complicated and slow down the process. On the other hand, untrained officers using metal detectors might cease using them because they think that they don’t produce any meaningful results.
      But training to properly use a metal detector is not a difficult task and virtually any officer can learn how to use a metal detector properly. Most of the time the reason an untrained officer found no luck using a metal detector was because of some very simple mistake that can easily be corrected. Once learned, it is incredibly easy to use and will only serve to cut the amount of time it takes to investigate a crime scene while at the same time producing far more thorough results.
      If the department already has a metal detector, there’s little point in having it if it never leaves the office. After all, think about how much evidence you’re missing out on because officers aren’t bringing it out into the field to aid with their crime scene investigations?
      Proper training and knowledge of the equipment are crucial not only to detect and find evidence but also to make sure that the evidence, once found, will hold up in court. A skilled attorney can easily pick apart and discredit evidence found with a metal detector when the officer doesn’t understand the equipment or how it was used. On the other hand, an officer who is highly knowledgeable of and capable with his metal detector can withstand a great deal of scrutiny on the witness stand. This increases the chances of the evidence you find with a metal detector staying in the game when it comes to trial.
      Knowing the manual, learning the terminology and basic operation of the metal detector is the bedrock, but it’s not the end of the story by any means. There’s no substitute for practice with a metal detector. That practice doesn’t have to be, and ultimately shouldn’t be, limited to practice in the field. Officers should, for example, take a metal detector to the shooting range. This gives them the opportunity to examine a number of spent shell casings to learn the difference between how a metal detector registers one versus another.
      From there, officers can proceed to more complex tasks like finding shell casings and spent round that are underneath three inches of soil. This kind of training shouldn’t be an obstacle to getting the metal detector out in the field. It should simply be there to supplement what the officers are doing during actual crime scene investigations.
      Metal Detectors Are Snipers, Not Shotgunners
      Some might think that there’s going to be a lot of false positives when using metal detectors for a crime scene investigation, but this is not the case. Dave notes that a metal detector can be set so that it only detects the specific type of metal in the caliber of ammunition that you’re looking for. So, for example, if you know that you’re looking for a steel-cased 9mm round, you can set the metal detector to only report results for that type of metal. What’s more, you can set the bandwidth so that it isn’t reporting common items like gum wrappers that might set off a metal detector.
      One common method used when searching for evidence using a metal detector is to very narrowly set the metal detector so that it only returns results for a specific item that you are looking for. Once an area has been swept in this manner, an officer can then go over the same area casting a wider net. This allows for an officer to find specifically what he is looking for before searching the same area to see if there is anything that he missed that he wasn’t looking for.
      The gun range allows officers to acquaint themselves with the nuances of a metal detector. For example, what kind of alert does one get from a 9mm as opposed to a .40 or a .44 magnum shell casing? You don’t need a crime scene investigation to do this. All you need are a bunch of empty shell casings.
      Field experience, however, will be the gold standard when it comes to learning how to use the metal detector. While basically anyone can be trained to find empty shell casings and spent rounds, there’s a nearly unlimited amount of objects that could be found at a crime scene investigation that could end up being meaningful evidence. Indeed, as many crime scene investigators might attest, sometimes the most unassuming object can be a piece of evidence when the context is understood.
      Finding such “odd” objects in a crime scene investigation is more art than science. Officers will just have to learn how to separate the wheat from the chaff through direct personal experience using metal detectors on crime scene investigations.
      So what is a metal detector going to pick up at a crime scene that a trained investigator won’t? You’d be surprised. Dave reports finding guns and knives with his that investigators failed to locate on visual inspection of a crime scene. But beyond that, there are, of course, shell casing and even spent round that can be identified. This begins the process of forensic analysis of a crime scene. Once such a shell casing or a spent round is uncovered, laboratory analysis can begin to find out, with shocking specificity, precisely what kind of round it was before it was shot based on where contact with the primer occurs and what kind of rifling left its mark. This is a common method of matching guns to a crime, but it can’t take place if there’s no spent round or shell casing to examine.
      A car might not sound like a very difficult object to find, but it would be if it was buried deep down. A metal detector in the hands of a skilled crime scene investigator, however, can detect an automobile as deep as 20 feet below the surface. This will uncover evidence that virtually any crime scene investigator, no matter how experienced, would miss even upon close inspection of an area.
      Metal Detectors Help Preserve a Crime Scene Investigation
      Metal detectors also reduce the impact on and disturbance of a crime scene. When locating and acquiring evidence from a crime scene, even skilled investigators can find that they unintentionally disturb the area. This is especially common outdoors, where natural terrain must, almost by the very nature of the process, be disturbed while officers are looking for evidence. Metal detectors, however, can significantly reduce or even eliminate the disturbance of crime scenes. Officers don’t have to get down on the ground to poke around for shell casings — they can simply wave the metal detector over the area and it will let them know if the shell casing is there.
      It’s not just police officers who can assist with crime scene investigations using metal detectors, either. There are also legions of willing amateurs who are happy to help. Metal detecting clubs offer a ready-made army of amateur investigators who are willing to bring their tools to the search. There is some degree of training involved to ensure that the volunteers know how to not disturb crime scenes. But once you have these amateurs trained, you will be able to exponentially expand your ability to search a crime scene and uncover evidence.
      Underwater Crime Scene Investigation and Metal Detectors
      Another area where metal detectors can help is with finding evidence underwater. This is a particularly shrewd investment of time and money for coastal police departments. Finding evidence underwater can be a seriously Sisyphian task, often yielding little in the way of results. But with a water-ready metal detector in tow, it can be far easier to unearth useful evidence from a crime scene. Officers must be trained in the proper use of such, as should volunteers. But this training isn’t nearly as time-consuming as one might think. And once the training has been implemented it can be used time and again, paying dividends almost immediately.
      One way to explore an underwater crime scene without disturbing either the scene itself or the ecosystem is to deploy the search team, who then simply use little markers known as “pingers” to mark an area in need of further exploration. The area can then be handed over to people who specialize in this sort of excavation.
      Underwater metal detectors come in a variety of models, including ones for saltwater, which reduces the number of false positives. Others can be towed behind a boat, removing the need for skilled divers to investigate an area.
      Underwater metal detectors need to be specially designed so that they ignore things like saltwater and black sand, which can trigger false positives. But the right metal detector with the right settings in the hands of a law enforcement officer who knows how to use it will uncover objects underwater that likely would otherwise have gone undetected.
      Metal Detectors Help Solve Crimes When Other Tools Fail
      As amazing as it sounds, this type of physical evidence was once thought of as nothing more than mostly uninteresting useless debris around a crime scene investigation. But now they are much more easily connected with evidence from crime scenes. And while fingerprints are not a magic bullet, they can often be taken from shell casings. There are also serial numbers on all rounds made after the 1968 Gun Control Act, adding another means of tracing and tracking shells found at a crime scene investigation.
      How much can a little piece of metal found in a tree tell you about a crime? A heck of a lot, actually. Even a little fragment of a bullet has rifling details on it that begin to paint a picture of what ammunition was used. The caliber of a standard round or the gauge of a shotgun, for example. From here, skilled crime scene investigators can begin to deduce what brand of ammunition was used. This, in turn, begins to form a picture of which specific weapon was used when committing a crime.
      A metal detector can find spent rounds in places that even skilled crime scene investigators comb-over for weeks. Oftentimes, these can be found embedded into some kind of wood. But even knowing that, searching for the spent round is a bit like the proverbial needle in a haystack. Keeping with this analogy, however — it’s a lot easier to find a needle in a haystack when you have a metal detector to help you get the job done. What’s more, when a metal detector is used it allows for better preservation of the area where the spent round is found. Thus, two pieces of evidence can be yielded through such methods.
      There are rather astonishing real-world cases of forensic analysis matching up a weapon to a spent round or shell casing found at the scene of a crime. A man who was known to Philadelphia police as the Ruthless Robber was a dangerous menace who would rob his victims, then shoot at them after they had handed over their valuables. And without the kind of forensic evidence we’re talking about here, they never would have matched up one of his shell casings to a weapon that was recovered at a totally unrelated traffic stop.
      In another case in Phoenix, Cleophus Cooksey Jr. was arrested for a double homicide. Within 48 hours they had him tied to seven other homicides, with police confident that they had caught a budding serial killer before he had a chance to really hit his stride.
      Finally, there is the case in Colorado Springs, where a police department was having a bear of a time solving a series of crimes in the area, including a drive-by shooting at a local mall. What police were able to deduce from a large number of shell casings and spent rounds paired with forensic analysis is that several gang members were sharing a single “community gun.” Without a large amount of data to work with, there is no way that these homicides would ever have been solved.
      The point here is that the more evidence you can collect, the better. While what you find might not be completely germane to your investigation, it might be helpful in another one. This is especially true if you live in a state where you have access to a statewide database of spent shell casings. And with a metal detector, you are certainly going to uncover more pieces of evidence with less crime scene disturbance than you would without one.
      Another example of the role that metal detectors can plan in getting a conviction is the common pastime of joyriders shooting at stop signs. The recovered shells from such incidents might not attract a lot of notice without forensic analysis. However, with forensic analysis, police departments can begin matching the spent rounds and shell casings up to much more serious crimes that are oftentimes totally unrelated.
      There are sweeping changes happening with law enforcement thanks to the revolution in forensic analysis. It was, and to a certain extent still is, uncommon for police to be able to solve non-fatal shootings. This is because of the amount of time, energy, and resources that have to go into these cases that oftentimes are better spent on fatal shootings.
      Modern forensic analysis, however, makes it much easier to get the information needed to get a conviction from a piece of evidence such as a single shell recovered at the scene of the crime. A metal detector, in the hands of an officer properly trained on how to use it, will help to expand the evidence pool, allowing for greater convictions of all crimes, non-fatal shootings included.
      What’s more, the man-hours involved in collecting evidence from a non-fatal shooting is significantly reduced when one has a metal detector on hand. The technology works from both directions to make investigating non-fatal crime scenes much more appealing even to smaller police departments with modest budgets: Better forensic analysis makes it easier to use the evidence provided, incentivizing collection. Better tools, such as metal detectors, make it easier to collect evidence in the first place, making the barrier to going out and collecting evidence lower.
      But the important thing to remember with all of this is that there has to be proper training. Training isn’t complicated or arcane — if you made it through the police academy, you can learn how to properly use a metal detector. But the training has to be done right at the beginning to ensure that officers are finding what they are looking for and not becoming frustrated by a series of false positives. Once this training is done and the metal detector comes into common use during crime scene investigation, officers will likely wonder how they ever got by without one in the past.

      Norvic asked why I was so proud of a VLF when I own and have posted much success with the other higher end detectors.  It was my post on rating the higher end Minelabs....so here goes.
      There are many factors to my craze and style of detecting, but my finds are the facts and not many people can compare, unless they too use the tools (detector) and hunt the style I do. I consider myself a gold hawg or gold pig.  I chase it all in terrains flat or tall. 
      Terrain -  I live in the Northwestern state of Idaho and much of my detecting in the surround state of ID.,  is Oregon, Nevada and occasional Montana.  For the most part, OR, MT and ID are pretty much the same with steep terrain mountainous rough country.  A day of electronic prosecting and hiking in such states, is much harder on the body for a guy my age, heck it’s harder for anyone.  Going to Arizona, Rye Patch and other Northern Nevada high desert areas is a treat for my body in more ways than one.  Maybe that is why so many people detect there?  It’s easy to drive and get to without walking…boy are most of us lazy?  YES, including me at times, but not in my home state (backyard where I play).  The ID, OR, MT mountains have steep ravines/canyons and the water is at the lowest point. Here is the many miles of hand placer workings, dredge tailing and hardrock mining ore dump piles.  The gold I am chasing is the stuff the old timers missed. 
      Pic below - This huge ore dump pile produced a few thousand dollars in Specimens.  This is the not so steep side and we had to tie off with ropes on the other side.  Half the targets would roll down the hill and need to be found during a break when we were at the bottom.  The PI's can't see this time of gold.

      Trash - Trash is my treasure in a way.. as I know the site has not been hunted as hard.  Trash is what most detectorists hate, and I too get that way on occasion, but I know if I'm patient, I'll eventually be rewarded.  A big factor I run into is 100 to 150 yr old man made trash from the early prospectors.  They left much of it on the hill, in the placer digs and tailing piles.  Many of the small mining camps were right on or near their diggings and they just tossed the old food cans, tobacco/coffee tins and worn out leather boots with hundreds of nails and broken, picks/ax heads shovels aside.  
      Pic below- In old tailing piles a lighter, faster, better ID detector is best.  He who digs the most non ferrous targets in a day, get to smile all the way home.

      Pic below- is the 1 pound specimen after cleanup.

      Tools – Know your detector, its limitations, strong and weak points.  Bigger deeper detector is great in flat terrain and areas with limited trash.  Raw depth and power is amazing to have, when the target you dig a foot or so deep is not a sardine can.  How about a shovel head at 2 feet or more?  Think about it and what you do when digging 5 or 6 of those an hour with your big deep penetrating detector.  What does your body have left in the tank?  My lighter VLF is easier to swing in rough terrain,  has better Iron and Target ID, is not as deep or powerful in trashy sites.  It saves me time from digging unknown iron targets, it saves me energy from digging deep holes, it saves me energy from having to pack around a bigger bulky detector.  The proper detector for the site is a must and in many cases my lighter, faster, better target Identification, sub $1000 investment is the right tool.
      Pic below - This golden oreo was recovered in old hand placer workings with my VLF.

      Having what I consider the best identification VLF gold detector on the market saves me time.

      Pic below - It was recovered at 16" with Minelab EQ-15" coil.  Yes I'll be going back over this area with the new CoilTek NOX 15" round as it is even deeper.

       
      Gold Knowledge-  This is confusing to so many people as they think gold is gold.  Yes I too used to think the same way.  Luckily I hunt a variety of gold producing locations and sites I like to detect and learn from.  My many years of comparing/testing detectors at such sites has given my staff and I an understanding of gold, its characters, density and how the elusive Au responds to the varying detector models from the different manufactures. Many of the nugget photos being shared on social media in years past were dense solid gold pieces and they are beauties.  That’s what the detector could easily respond to. In more recent years, the sizes of the nuggets became smaller and we started reading about and seeing some nice specimens.  The newer GPX detectors with their advanced tuning and soil timings (Fine Gold) would outperform their older brothers (SD/GP’s) on smaller and courser gold, so when get to make more of those finds and share them.  Most recent years has us using SDC-2300 and GPZ-7000’s.  Again, the gold gets smaller and the amount of crystalline gold, wire gold, salt/pepper specimens are being unearthed with these detectors supersedes that of their older brothers the GPX series.
      Pic below - This softball sized specimen was found with a VLF and has multi ounces of gold.  VLF picks it up deeper than many bigger detectors.

      Pic below - This beautiful 3" long quartz and gold specimen came from a trashy ore dump pile with a VLF.
       
       
       
      Pic blow-  These quartz cocoon wire gold specimens bring a premium and come out of hard rock ore dump piles.  

       
      Pic Below - The PI's don't see these rare pieces, the 7000 barley does on a select few.  

       
      Pic below - I have a feeling the extra sensitivity of the new GPX-6000 will do even better.
       
       
      Proof – The facts are in the vault at the bank.  I own beautiful specimens pieces recovered with detectors and have tested many on a variety of detectors.  I have gold finds that are multi ounce pieces and they contain 2 or 3 ounces of gold in them, but for some reason an SD or GP don’t see them, even less than an inch.  I also have such pieces my GPX 5000 does not see, but my GPZ-7000 does.  What is most amazing, is I have pieces of gold with multi ounces of metal and even the ZED has issues or can barely respond an inch or two away.  If this is the case, then why do I have these find gold pieces of art?  I’ve taken the time to test and learn my detector tools and have found a certain trusty VLF sees them all, can ID them all, is lighter in weight and so I get to hunt longer, saves me energy since I don’t dig as deep for unwanted targets.
      Pic below - This specimen came from dredge tailing and the speckled pieces like this get missed by most PI's.

       
      Pic below-  Over $800 in gold in this 3 ounce specimen and my VLF does better than my GPX-5000 and my SDC-2300.  The SDC goes deeper than the GPX.  You better know your gold and your detectors capabilities or lack of.

       
      Pic below - This 3 ounce specimen was found in trashy hand workings.  I actually had a GPZ-7000 here for a couple hours and gave up because of the amount of item trash.  A GPX-5000 with DD coil run with DISC mode would be better than my GPZ, but then again my NOX does even better.

       
      Better target identification of my NOX, is most important at the site this 3+ oz'er came from.

       
      GPX-6000 – A new tool and one that has Gerry very very excited. Now we are about to get a revolution of Geo Sensing Technology with PI power and capabilities for a wider variety of gold textures, densities, characters and sizes.  Minelab (and their track record) is even telling us some of such capabilities and so I and a few of the guys who do not like to miss gold, are getting ourselves prepared, getting our old sites, lined up and making sure we are going to take advantage of the stragglers.  Remember when the SDC-2300 and GPZ-7000 came out and all the slow response from the majority.  You folks missed the opportunity of a lot of gold.  My guys and I were killing it in NV and AZ on those so called worked out sites.  Was it a gamble to spend that kind of money?  If that’s what you love/enjoy and if you have a good track record with Minelab, it’s bet I’ll take most every time. I don’t lose detector bets very often.
      Pic below- This stunning collectible specimen was found by my brother with his SDC-2300.  It came from a place he had previous hunted and found gold with his GPX-5000.  The 5000 does not even whisper on it.  Minelab claims the GPX-6000 is more sensitive than the SDC-2300 & GPZ-7000.  I can't wait to use the GPX-6000 at the site and many others.

       
      Hopefully this story and the pics I shared will help educate some of you on how the different detector technologies produce more gold.  I realize it's hard to put down your old reliable detector as it has probably and hopefully served you well.  If your sites are getting thin of targets and or gold, just maybe a new detector can put the smile back on your face? I'll go back to this simple statement I have said below in other posts and it is the absolute truth.  You can't find what your detector don't see.
      PS - I’ll be honest though, for me it’s the lighter weight, better ergonomics, not being tethered in a harness and User Friendly that has me sold.  The extra gold my new GPX-6000 is going to find, is a bonus.
      PPS – I’m just as eager to test the GPX-6000 with some of my gold and see how much better/worse it does than my GPX, SDC and GPZ. (I'm educating myself).
      PPPS – I still feel there will be a place for my VLF, as it’s lighter, and have better target ID.
      See you in the gold field, where the most knowledge is learned.  Or speed it up with our 3 days Field Training at www.gerrysdetectors.com
      Happy Hunting.  Gerry
