      I put all my gear in the car the night before ready to roll as I was intending to go for a solo mission to try find a nugget, or a flake, which ever comes my way, I am happy either way ūüôā¬† I sent Kiwijw a text message that morning as he hadn't been on the forum asking if he'd like to come along as I knew he wasn't working that day and he was all for it.¬† It was¬†unusual he hadn't been on the forums but it's because his computer had broken down so I told him I'd take it home with me and fix it up.
      The day was off to a cool start, I left home and at the time I think it was -5 degrees celsius and very icey on the road, black ice everywhere. I was in a thick fog when I left home to head to John's to pick him up but that cleared up about halfway to his house, it was about -2 when I got there I think and nowhere near as icey up his way.  We jumped in the car and off we went, the roads were much better up his way as it was nice and sunny.  
      We went to a spot we have been to quite few times before and had success, I call it the shotgun pellet place as there are zillions of them there. I think I've even done a solo mission there, I don't have any record of that as I obviously was skunked if I did but John mentioned I have been there before myself and I vaguely remember it now I think about it.  I've done a few solo missions to various places but rarely have any success on them for some reason and I only tend to remember times when I do well.

      Cool looking rock at the area I was first detecting, looks like a broken easter egg, it looks like its a big hollow rock that some has broken off over the years.  Maybe old timers used it as a hut, I know I would.
      We started off detecting, John on his Zed and me with my 4500 and my new Nugget Finder 14x9 Evo coil which I'd been dying to try out but just hadn't had a chance.
      I'd found nothing by lunch time except junk and If I recall correctly John was up to number 3
       
      My days junk collection, I had quite a few more shotgun pellets but they fell out of a tiny hole in my pocket.¬† That little bit of wire on the far right side screamed out as loud as a 22 shell, puzzled by that.¬† In the process of recovering some junk I used my GM 1000 as a pinpointer, the spot was really muddy so I tried to take my coil cover off to give it a clean as I was right at a creek as I was going to put my Monster in my backpack so it's¬†not left sitting there out in the open in case some passer by stole it, unlikely but I'm cautious of thieves after living in Oz¬†for years and having house and car break ins and so on over there.¬† John leaves his Zed lying around like that, it scares me ūüôā¬† So I tried to pull my coil cover off and my coil cracked, a big crack too just by me using my fingers to push it in a bit to get the cover off.¬† I wish they were tougher epoxy filled coils.¬† I've since spoken to Minelab service who said they will replace it for me, see this link for photos of the crack¬† ¬†More excellent service from Minelab, thanks ūüôā
       
      John come walking over and showed me his finds and we had some lunch.  John suggested I go try detect some throw out piles from the old timers as it may increase my luck and showed me where they were and off we went detecting again.
      It was only about 20 minutes and I had my first hit, right next to a big hole someone else had dug to recover a nugget, probably John as it was a big hole like his pick makes 

      My little hole at the top, someone elses big hole below it, my little nugget was down about 10cm to 15cm I would guess.



      About 30 minutes of swinging later on top of another pile which was covered in soil and grass and not rocky like the last one I had another good target, It sounded promising and it seems junk in this area is uncommon as I'd had no junk digs since moving to it.



      I had to smash up the ground here to retrieve this one, it was in the shade and the ground was frozen solid, it actually made the recovery quite easy as the clumps of dirt were coming up as frozen blocks so I could sweep each chunk over the coil until it sounded off, then melted the target clump in my hand to get the gold out.
      I started swinging around further along this pile and there was a giant bit of schist and it was giving me a good signal, I spent about 20 minutes scraping the moss off and checking it all for the target and also breaking away the top layers of the schist trying to find where this signal was coming from, it had me stumped.  I wasn't sure what to do, I was going to go ask John thinking possibly it's some sort of hot rock situation but I could see him off in the distance, too far away and I was unsure I'd find the spot again if I left it so I decided I'd try move the rock, maybe the target is under it.  It was in frozen ground and had suctioned itself down, it was also FAR to heavy to lift, I used my pick to dig around it a bit and lever it up, this took a good half an hour and I was exhausted, I managed to move it a tiny bit which relieved the suction, it also had me rolling down the side the of pile as I took a tumble when the rock finally gave way. 

      You can see the top part of the rock here where I was chipping away at it trying to find the target inside it.
      Now that the suction was gone I was able to lever it enough that I eventually slid it down the side of the pile.  I eagerly checked the area where it was and bingo, the target sound was still there.

      You can see the size of the rock here with the indent in the ground where it came from.  The rock would of been about 20 cm thick too and then the nugget was down another 5 cm or so in the soil under the rock.
       

      and it was my biggest nugget of the day ūüôā

      I went to go show John my find and tell him the story and he said I should go scan that area a bit more as there could be more, we only had about an hour of light left so I wandered back to try find the spot, and wouldn't you know it, I couldn't find it, lucky I didn't leave earlier to try get John to help move the rock.
      So all in all a good day out, fixed up John's computer today so he'll appear back on the forum tomorrow no doubt as we are heading out for part two of this mission so he'll get it back tomorrow, it needed a new motherboard.  He had someone nearby to his house look at it as it was running very slow and they did the usual things like spyware checks and cleaning the dust out and so on and had broken a fan mounting clip for the CPU in the process of the dust cleanup I guess, John said it got really noisy after they looked at it which is normal as the fan would be going top speed trying to cool the CPU with the poor contact of the heatsink and shortly after it died and wouldn't post (display a signal on the screen), I guess the cpu heatsink being so loose caused the CPU to overheat by not being clipped down properly and caused the motherboard to die, or else it was a huge coincidence the motherboard dies the day after they clean out the fan and break its mounting clip.  In saying that I've not seen a motherboard die from heat in this manor before, although I've never seen someone run one with the heatsink not clipped down properly.
      As for my first proper detect using my new Nugget Finder Evo 14x9, I love it, It seems just as sensitive to tiny gold as the little Joey coil if not even more sensitive but punches deeper, It's ability on small targets feels like using a high frequency VLF.  It's going to be my stay on coil from now on, the little Joey will be perfect for tight places and creek detecting and situations where a smaller coil is required.  I can highly recommend the Evo coil. Thanks to all the people who recommended to me to buy the Evo coil.  I am very happy with it.
      Stay tuned for John's portion of the mission when he gets his computer back tomorrow ūüôā¬†¬†

      I have used the Minelab GPX 5000 since it was introduced, and in fact probably owned the first one in Alaska. I have used the Garrett ATX also since it came out with one of the first units off the production line. I have been putting this review off while I got to know the ATX. I now have over 100 hours on the detector in a variety of environments so the time has come.
      This metal detector comparison review was very challenging for me to write. It pits two very different yet very similar detectors against each other. In a way it is almost like discussing three detectors instead of two, and there is the issue of a huge price difference. I apologize for the length but this is a case where I wanted to be as thorough as possible on the subject. This is the review you will never see published in a magazine!
      In a way it is all about that price differential. If the two detectors were priced similarly there would be much less debate than is going to occur amongst people and a far easier buying decision for some to make. For me personally it really is a story of the Garrett ATX being two very different detectors at once and so I will start the review there.
      I have been metal detecting over forty years now, and metal detecting is very important in my life. Not a day goes by that I do not think about, write about, or actually go out metal detecting. Luckily for me a large chunk of my income is derived from metal detecting and so I can justify a collection of metal detectors for what I do. I engage in quite a few detecting activities and I strive to have the very best detector possible at my disposal for whatever it is I am doing. Because of this I am constantly on the look for new detectors that might help me in some way.
      However, now that the technology is maturing I have the bases pretty well covered. The only thing I was still looking for was a detector that satisfied me while water detecting in Hawaii. Every other detecting scenario I have covered to my satisfaction, but every time I hit the water in Hawaii I was left wanting something better than was available. The combination of salt water, volcanic rock, and military grade electrical interference is very challenging for any detector.
      What I generally want is a combination of stability and power with good ergonomics. The perfect detector should only signal on desired targets and nothing else, at good depth, while feeling good on my arm. I obviously reject detectors that get poor depth - these are usually the lower price detectors. Most top tier models are very competitive in the depth department. Other detectors I have put aside solely due to an inability to handle electrical interference. Fine machines otherwise, but unstable in an urban environment. Other detectors are too noisy in mineralized ground or too chatty in dense trash. And finally, some detectors are holdovers from the old days of heavy and clunky. I do not like detectors that make my arm hurt!
      I was therefore very excited when I heard the Garrett ATX was on the way. I was very familiar with its predecessor, the Garrett Infinium, which was tantalizingly close to my perfect Hawaii detector. Unfortunately the Infinium suffered in the stability department. I was also aware of the Garrett Recon Pro AML-1000 military demining detector. I was intrigued by its having a non-motion monotone search mode and wondered if that could be incorporated into a new improved "Infinium Pro" model. I not only had Hawaii in mind but started envisioning scenarios involving underwater sniping for gold employing a metal detector.
      Add to this that neither Minelab nor White's seemed interested in putting a waterproof ground balancing pulse induction metal detector in my hands. I never expected it would be Garrett that would come out with a second generation model based on the Infinium before anyone else got to first base.
      I have told you all this to explain what I was expecting and hoping for in the Garrett ATX. The fact is Garrett delivered with flying colors on my desires and the ATX is now one if the most important detectors in my collection. I have already paid for the detector with jewelry found and it is the Hawaii detector I always hoped for. Garrett ATX in Hawaii If we are talking about the Garrett ATX as a new waterproof detector for use on black sand or volcanic island beaches the review can end right here. The Garrett ATX is a superb detector for those conditions and well worth the money.
      There is only one fly in the ointment. If you look at the full page ads for the Garrett ATX it is clearly being marketed as a prospecting detector, and one pretty clearly aimed at Minelab's top end models. Specifically "The ATX performs head-to-head with the most expensive prospecting detectors in the world."
      Interestingly enough this idea was not even on my radar. I had always thought it was a huge mistake for the Infinium to be set up as direct competition for the high end Minelabs. Anyone involved in that remembers the hype and resulting disappointment and backlash. The Infinium eventually found its place but more as a water and relic hunting machine than a prospecting detector, although it is a capable enough unit. My hope was to avoid a similar scenario with the ATX. I do not like hype and prefer things to be under sold so people are pleasantly surprised when their expectations are exceeded. Hype leads to disappointment when inflated claims cannot be met.
      The reality here however is that Garrett has chosen to make prospecting the battlefield of choice. There is a lot of money at stake here for a lot of people, and so I am going to do my best here to compare the two units as dry land prospecting detectors. I think we can all agree that if you are looking at both the Garrett ATX and Minelab GPX 5000 and need the detector to be waterproof the Garrett ATX wins hands down.
      The funny thing here is that if Garrett was gunning for Minelab then in my opinion they went about it the wrong way. I get the distinct impression the design process was backwards. It was not a matter of "what do prospectors want in a metal detector?" I think it was "we have this housing on the shelf we developed at great expense to go after a military contract. We need to leverage our development cost by putting something in that housing we can sell to the public." In other words, I do not see any sign of design following function. All I see is a prospecting detector crammed in a box inappropriate for the desired end use. If Steve Jobs was into metal detectors he would be rolling in his grave. I will have to suffice instead by simply shaking my head at missed opportunity. I will explain more about that later.
      Let's set ergonomics aside though for now and just talk about straight up prospecting performance. How does the Garrett ATX fare against the Minelab GPX 5000 on gold in mineralized ground? I have done fairly extensive tests but I do have to throw in the caveat that the world is a big place and when you discuss prospecting detectors one truth is paramount. It is all about the ground mineralization and hot rocks. What works well in one place fails in another, and for this reason alone I cannot offer 100% assurances. I have spent a month traveling Western Australia detecting every day and so I am quite familiar with what prospectors face there. I am not about to begin to offer more than an opinion about how these two detectors fare in the worst Australian ground but I do think my conclusions will prove to be true. I can tell anyone right now knowing detectors the way I do that either machine will prove superior at certain locations given their differing capabilities.
      In a nutshell, the Garrett ATX has a ridiculously good circuit. The engineers at Garrett have done a superb job of producing a detector that out of box performs extremely well on a wide variety of gold in a wide variety of ground conditions. I tested both units in some very red mineralized soil, both outfitted with stock DD coils. The ATX comes with a 12" x 10" DD coil. The GPX 5000 comes with two coils, one of which is an 11" round DD coil and this is what I used. The nuggets ranged from 0.1 gram to 6.5 ounces.

      Test conditions
      The impression I was left with was definitely not how the GPX 5000 blows the ATX away but instead by how well the Garrett ATX does. It is impossible to not be impressed by how well the $2120 detector does when run head-to-head against a $5795 detector. Garrett has done a fantastic job and in my opinion their advertising claims are not off base. This is a serious prospecting circuit well worth consideration.
      The two detectors basically differ in the range of gold they find best. The Garrett ATX skews towards the smaller more commonly found gold nuggets. The Minelab GPX 5000 skews towards larger gold nuggets that tend to be the goal of professional prospectors. Out of box with similar coils the ATX will find small gold nuggets the GPX 5000 would normally miss without special coils and tuning tricks. It does this simply and with no fuss. However, in mineralized ground with similar coils the GPX easily bests the ATX on large nuggets. By large I mean one ounce and larger and by easily I mean by a margin of 10-15%. The GPX 5000 does this using a coil that in my case had never been on the detector before. Most Minelab users would never consider hobbling the detector by putting the 11" round DD coil on if hunting large nuggets at depth. It is informative therefore that even doing this in the interest of "fairness" and with nothing more than stock Normal timing with Gain bumped to 16 (out of 20) the Minelab GPX 5000 easily outperformed the Garrett ATX on a 6.5 ounce nugget. The ATX was at max Gain of 13 for the test.
      Now the depth differential here was only about two inches but I have to throw in the huge caution note again that it will vary depending on ground conditions. Absolute depth was about 17" ATX versus 19" GPX for good solid signals. The kind nobody can miss. Again, do not take these as some sort of magical numbers as ground conditions and even nugget shape and alloy could cause you to get some surprising differences. That is why I hate mentioning exact depths and differences in most cases and just stick to relative conclusions. But you are going to ask so there you go. For reference a Fisher Gold Bug Pro with 13" round DD coil and White's GMT with 14" elliptical DD both with settings jacked to the max were barely able to obtain this solid gold 6.5 ounce nugget at 12" in this ground and the GMT in particular would not really have been able to hunt maxed out the way it was.
      Depending on who is reading this the response may be "really, only two inches?" or "wow, two whole inches!" Similarly, it is interesting to see the GPX with DD coil scrub a little nugget with no signal that the ATX easily detects at a couple inches.
      This however does end up being my basic and not new finding by any means. Others have reported similar results. The ATX does better on small gold and the GPX on large straight out of box with stock DD coils.
      I do believe the GPX has more ability to handle more varied and more intense ground conditions and hot rocks due to its many adjustments. However, this is more a belief than a fact as so far the ATX has easily handled everything I have thrown at it, including salt water, basalt rocks, and electrical interference in Hawaii. Garrett does make use of a salient fact in its advertising. The ATX handles a wide range of conditions with deceptively few settings. This makes it very easy to set up and it avoids a common complaint with the GPX detectors. They are so complex people are often left wondering if they have the optimum settings for the conditions. I know for a fact from observation that many people tend to use timings that are too aggressive for the actual conditions when using a GPX. The tendency often is to find something that seems to work well and then to just default to that way if doing things, even if conditions change. To get the best performance out of a GPX does require that a person be somewhat of a tuning wizard.
      The bottom line for many more casual prospectors in the United States especially is that the Garrett ATX represents a fantastic value. It is truly impossible to say but in my case at least most of the gold I find in the US with my GPX an ATX would have found it also. In particular when hunting areas where bedrock is a foot or less the ground would have to be extremely hot indeed for the ATX to not only find what the GPX will but to have an edge on the more common small gold. Even in deeper ground as long as the gold is measured in grams and not ounces and the ground not extremely mineralized the ATX is going to be a close match with the GPX. Again, out of box with stock DD coils.
      Where the ATX is going to clearly come up short is on large nuggets, especially those sought after 1 ounce and larger nuggets at depth and on gold in the worst mineralized ground and hot rock locations. To be perfectly honest I feel my putting an 11" inch round DD coil on my GPX 5000 in the interest of being fair does not reflect for one second how I look for gold. I am not out there being fair, I am out there looking for gold. I will be running a larger mono coil with settings optimized for larger gold and then the difference in large gold performance between the ATX and GPX is even more pronounced. I would consider a 10-15% to be a bare minimum advantage gained while in effect running the GPX with its hands tied.
      I have not done comparisons on the iron discrimination systems but I find the method used by the ATX to be inherently more reassuring. The GPX reacts to shallow ferrous targets by blanking out, a sort of non response. The ATX has a momentary ferrous check that kicks in at the touch of a button, and that gives a low tone growl on iron, which provides a more nuanced and natural response expected by most detector users. I am not a big fan of using discrimination on either unit but I did find the ATX method more to my liking for confirming shallow ferrous stuff as trash that I already thought was trash due to the response. Note that on either detector the ferrous rejection only works on shallow items and only with a DD coil. The amount of rejection is adjustable on the GPX and preset on the ATX so more tests really need to be done in this regard to determine which is the more accurate and useful system.

      Minelab GPX 5000 and Garrett ATX (Minelab outfitted with optional Nugget Finder coil)
      I do own both detectors and there is a simple reality here. If I am going looking for gold in the water, be it jewelry or nuggets in a creek, I will grab the ATX. For any other prospecting, the vast majority of it, I will be using the GPX 5000. I am not sure where the line between casual and serious is, but I am way, way over on the serious side. I spend a great deal of time targeting and hunting deep ground looking in areas where very large nuggets have been found historically. Most of the ground I detect I am hunting because it has produced nuggets weighing a pound or more in the past. I hunt tailing piles a lot so bedrock is tens of feet down, and the gold can be at any depth from shallow to extremely deep.
      I think most professionals would tell you that small gold is what happens along the way while looking for the big stuff, and at the end of the day it is the big stuff or the lack of it that makes the difference. I found over thirteen ounces of nuggets metal detecting in 2013 which is no great sum of gold in my book, but well over half of it was in the form of two nuggets, one weighing 6.5 ounces and the other 2.37 ounces. Now in this case the ATX would have found both these nuggets. Yet I would not use anything but a Minelab GPX for what I am doing. I am spending a lot of valuable time going over ground that I may only get one shot at. I plan these things well in advance and not only time but good money is invested in taking my best shot at getting good results. I basically cannot afford to be running anything that I feel does not give me the best chance of delivering that make or break it big nugget. One nugget can make all the difference between a month of lackluster results and fantastic success.
      If both the Garrett ATX and Minelab GPX 5000 detectors had exactly identical electronic performance I would still be swinging the GPX. I am on one hand very impressed with the ATX as a nugget detector and on the other hand very disappointed by it. The up front decision to use the Recon AML-1000 housing is an automatic fail from a nugget detecting perspective in my opinion. It adds not only needless weight but weight that is very much an impediment in rough, uneven terrain. This is accentuated by a stock coil that is sensitive to knocks and bumps. It requires an extra level of coil control to manipulate the detector in such a way as to not produce excessive false signals. This differs from Minelab coils that basically do not false at all unless something is wrong with them. I would caution anyone using a detector the way I do that the ATX requires extra care as regards the possibility of repetitive motion injury. Trust me as somebody who detected too much one year and ignored the signs this is something to regard seriously. A harness is a must for weeks of long daily use of the ATX. I shudder to think about how the detector feels with the 20" long rear mounted mono coil hanging off the front. That is an ergonomic nightmare.
      The ATX features silicone lubricated battery door o-rings that collect dirt. The coil connectors also have o-ring seals and even worse delicate pin connectors subject to damage if not carefully lined up. The headphone connector is similar to the coil connectors. All these are required to make the detector waterproof and not only unneeded for normal dry land use but an impediment as regards serviceability in the field.
      The coils are sold as a unit with the telescoping rod assembly adding needless expense and weight and making carrying an extra coil around something to be avoided. The rear mount enables the ability of the detector to fold up but is another weak point from a serviceability aspect and ergonomically the worst way to mount a coil.
      I always considered ergonomics to be the easy low hanging fruit for anyone considering manufacture of a detector to compete with the Minelab PI series, and I am frankly amazed anyone could make something even heavier I am less excited about handling. It is an absolute fact I would put the GPX aside for an alternative, even if that alternative was next best in overall gold ability, if it offered a big advantage ergonomically. I in fact often do decline to "harness up" and set the GPX aside in favor of a lightweight VLF at times because I am just too tired or not in the mood. More importantly, in steep terrain bedrock is often shallow and so when hunting hillsides and slopes there really is no advantage to using a GPX in ground only inches deep.
      I would very gladly use a properly designed Garrett ATX instead of a Minelab GPX in many situations that I currently encounter. In particular areas where bedrock is less than a foot deep or in areas where large nuggets have historically never been seen. The only reason right now that is not going to happen is I do not want the ATX on my arm. Yes, the ATX has an inherent advantage on small gold but nothing I can't negate by putting on a small mono coil and running the GPX hot. No, in my opinion Garrett missed a major opportunity to wow somebody like me by putting a fantastic prospecting circuit in a package very inappropriate for the target audience.
      Metal detectors are tools. Now the fact is that for the average person Craftsman tools do just fine and represent good value. But the guy making his living with his toolbox is probably going to be investing in Snap-on tools. It is an apt analogy accentuated by the real performance difference that exists between the Garrett ATX and Minelab GPX detectors on the kind of gold most pros are looking for. The vast number of accessory coils and other aftermarket options on top of a well proven platform makes it an easy decision for the serious prospector. Minelab makes a tool designed specifically for a certain job. The Garrett ATX unfortunately I feel is a duck out of water when employed for normal prospecting uses.
      I do have to say my hat is off to Garrett for producing a detector that is the first to really give Minelab a run for the money. I hope they do follow up and produce a model expressly designed from the ground up as a dry land prospecting machine. It may well become my primary prospecting detector if they do so. If you have read this review carefully you should understand the issues involved. For many people wanting maximum bang for the buck a Garrett ATX straight up and used properly is a real bargain in a PI prospecting machine. It can and will find gold and find it very well. The guys like me (you know who you are) that probably already have a Minelab PI plus extra coils, batteries and so forth can continue waiting for the next big thing in nugget detecting. You may also consider the Garrett for exactly the reason I did. It is waterproof, and currently is the closest thing you can get to a Minelab PI in a waterproof package.
      In closing I am curious to see how both detectors do for me this year. The ATX has the lead with about 2.5 ounces of gold and platinum jewelry found so far. I plan on using it often to hunt jewelry every chance I get in 2014. The GPX I will once again be taking to Alaska for a couple months of nugget detecting which may or may not pay off with a large nugget found. I will be hunting the right places but large gold is rare almost anywhere you go. Given the lead the ATX already has the GPX has its work cut out for it so it should make for an interesting year. For those of you trying to decide between these two very fine metal detectors I can only sympathize and count my blessings for not having to make such decisions. However, I hope this helps you with your decision because I have done my best to try and do just that. Good luck and good hunting!

      I have the pleasure of sporting the worst cold I have ever had. I should be doing battlefield metal detecting, but for the past 5 days I am just enjoying this cold.ūüė° So, not feeling like doing any real work or going anywhere, I decided since my beach hunts are over until fall, I would gather up and count and post all my finds for the whole season‚Ķ. A season wrap up, if you will. Since I couldn‚Äôt muster up the enthusiasm to do everything in one post I figured I would at least post the good stuff. So here it is ‚Äď the Gold and Silver finds from last Labor Day thru this Memorial Day. I managed 36 beach trips, not sure how many hours but probably about 250 hours of detecting. The breakdown goes like this: Gold total ‚Äď 36 pcs, at an average of 1 pc per visit. Silver total (coins and other) ‚Äď 207 pcs, at an average of 5.75pcs per hunt. The breakdown for silver is: 146 coins consisting of 6 Half Dollars, 27 Quarters, 98 dimes, 15 War Nickels. The other items (rings, chains, earrings, pendants, odd broken pieces etc.‚Ķ - amounted to 61 pcs. Coming later ‚Äúsomeday‚ÄĚ will be the clad count, and a breakdown of the junk items to show the ratio of good to bad that comes with the territory. It was a great season for me and I look forward to shifting gears and doing the battlefield hunting and maybe some cellar hole hunting if I get a chance. And since I have neglected my other hobbies, maybe doing some of those until Labor Day.¬† Most of the gold was found because of the Equinox, probably 75-80% of it. Most of the silver was found with the GPX (at depth) probably 90% of it.¬†Not a great comparison since I have found most of that gold in 8 visits and the silver was found with about 28 visits and I was specifically looking for deep silver, so I did not use the Equinox for that, mainly due to the fact that it was busy finding gold ¬†Seriously, I was too inexperienced to get that kind of¬†depth out of the Equinox, as most of that silver was in the 14" deep range, basically sitting on a clay layer with the sand above it containing small wisps of very fine black sand.¬† But that combination worked well for me and I'll probably stick with it for a while.

      Has anyone had any experience with these things? 

      Electromagnetic and magnetic interferences could be extremely annoying when you are looking for that hard to find gold nugget. Most of the noise is picked up by the search coil but a significant level of noise is being picked up as well by the sensitive electronics inside the control box.
      The control box is made of aluminium therefore the magnetic field easily penetrates it.
      To prove that, approach a magnet to the right side of your detector when switched on. 
      Millions of less obvious noise signals are interfering with your detector.  
      We have developed this Shield from the best quality material primarily used in sensitive 
      medical and scientific electronics. After years of studying and testing different materials we have found this one ticks all the boxes. 
      I have revisited the places where I've previously cleaned up and found more gold after installing the shield.
      It is 0.35 mm thick, held firmly around your control box by the armrest and  the new improved version with dual layer shielding on the right side is only 175 g!
      We have tested it on the GPX 5000 with amazing results such as quieter threshold, better GB, resulting in slightly increased depth.
      The shield allows you to increase the Rx gain by a notch or two without compromising the threshold. Use Inverted Response when hunting for big deep nuggets.

      I noticed it on Ebay today while I was looking for a cover for my GPX.
      I have noticed I've been able to quieten down my GPX by opening the control box up and scraping some paint away where the shielding touches the casing, on one end they had scraped away paint from one screw point during production, and the other end had no paint scraped away at all by the factory so it's sheilding was basically useless.  By scraping paint away from a few areas on each end of the detector I was able to give the GPX a bit of a noticable quieten down.  I am sure on later models Minelab would of scraped away more paint but as mine is a very early model made in Australia version this wasn't done.

      So now I've got a Gpx 4500 my phobia of headphones is really getting to me, I hate the things.  
      I want to hook up an external speaker to it, I have tried an external speaker I had laying around and unfortunately the amp on the battery doesn't kick in using it so I assume its to do with it having a stereo plug on it.  
      Kiwijw mentioned he thinks you need a mono plug for the amp to kick in, if this is the case I'll just cut the end off and add a mono plug but I wanted to be sure before doing this that's what kicks the amp in.
      I've also ordered what seems to be the popular speaker for the 4500

       
      However it comes with a 3.5mm mono plug, so I'd need to change that to a 6.5mm plug (1/4")
      The problem I see is they're being advertised for GPX detectors looking like this

      So they've put a stereo plug on that one, and advertising it for GPX 4500's
      Would that not mean the amp won't kick in and you'd need a booster? 
      Does anyone know for certain what makes the batteries amp kick in? 
      Even JP sells his one with the stereo plug, I'm puzzled

      Hi guys, I have been sending on to Simon (phrunt) some old video footage I took to show him the sensitivity & depth of the 4500 on pretty small gold. using the Minelab 11" Commander Mono coil. That coil found me a lot of gold, small gold. All these clips were taken on the same detecting mission & were pretty much one after the other. The day was windy, as you will see, & it was before my days of using a scoop to retrieve targets. Consequently I got the dropsy's & made a meal of the recovery in the first vid. Hence it dragging on far longer than it should have. Sorry about that. The reason why I never made it public back in the day. I could have edited it but didn't. Just the raw footage. Hope you enjoy. Cheers.
