  1. Daniel Teague Published on Dec 5, 2018 Some of you guys were curious as to the tone differences between a Minelab GPX and Whites TDI. This is the GPX 4800 and TDI Beachhunter and a little bit of why I like the GPX better when it comes to relic and beach hunting.
  2. 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 https://outbackprospector.com.au/jonathan-porter-gold-prospecting-external-speaker/ Thanks
  3. Hi guys I was wondering if anyone out there could tell me what ones best of these two coils I've herd alot of good things about the 12 round nugget finger coil but like the eleptical coils as can get them in places the round won't go and I know the 12x8 is fairly new .but thought I'd ask if anyone has any experiance with it compared to the 12 round ..on depth and sensitivity?
  4. hi guys i was just wondering if anyone out there knows if its possible to change the high and low tones individually on a gpx . i think i already know the answer as havnt managed to do this and ive used this machine for over a year and found lots gold along with my sdc and gold monster .but encase ive missed something i thought id ask and the reason for this question is as follows i recently brought a tdi sl just to have one and even tho it lacks the ooomph of my 4500 thats been modded . i absolutly love the difference between high and low tones or high and low conductors .the tones are so different were i still struggle to tell the difference between a high low or low high on the gpx without taking along a we lead sinker or small nugget to wave over the coil to compare as the sounds are so similar .. id love to be able to change the tone of just the high and then just the low so they are vastly different .so does anyone know if its possible to do this ? or tips to make it more notably different thanks Craig
  5. I find this stuff really interesting, to the point I'm making my daughter her own little detector, I've got all the bits together and now it's time to start making it. It will be more of a pinpointer, a bit of fun however it won't have any sort of housing unless I can come up with something. I could make it like an early model detector out of wood or something πŸ™‚ So here is a video of a guy making his own coil, pretty simple one but looks like it works alright, he just used coax cable for the coil cable, I guess it's well shielded and strong. I thought some others may find it interesting, more to see what's inside a coil more than anything. I expect the genuine coils will have tighter wound wires and the flat wound coils would be much more difficult to do than this. I suspect most the cost of coils is labour, especially when a lot are handmade still like Nuggetfinder coils.
  6. Published on Apr 12, 2018 by steelPHASE In this video I talk about the settings on detectors, aiming mainly at the Minelab GPX, SDC and GPZ series. My aim is not to tell you what settings to run, but rather give you the knowledge to make informed decisions on settings out in the goldfields. Now I am no Einstein so I do stumble and fluster in a few spots but I have edited in some text to make things clearer (hopefully).

    DIY Wireless GPX 5000

    Just thought I would share my wireless setup for anyone thinking of trying this. I have used Avantree Saturn Pro (Low Latency) bluetooth Transmitter/receiver and some Camcorder batteries. I have also got a couple of Lipo batteries from my RC which run the 5000 really well as they keep their voltage for longer. The leads I made myself with genuine power plugs and a deans RC battery plug and a 1/8 audio jack so as to go straight into bluetooth wireless module. These little module are very good and are lasting well over the 8 hour mark on a charge, and their size and weight make them very versatile. The 7200mah pack and wireless module come in at 325 grams with leads included this lasts about 5-6hours I have made up a couple of 3400mah packs with 18650 cells and these weight 180 grams with module and leads and lasts about 3 hours. I have a 5000mah Lipo hardcase which weight 200 grams with both wires and module, this goes for 7 hours before the low voltage alarm comes. Lipo batteries aren't for everyone as they can be a little volatile, but I am yet to have one explode and treat them with care when charging with a good lipo charger.
  8. A few months ago when talking to the guys at nugget finder about coil options they hinted at a new small coil coming out soon, here is the news i was waiting for. Some exciting news for GPX users, a super sensitive coil with good ground coverage in the evolution windings, will be interesting to see its performance especially compare to the new coiltek 9" and also the SDC. From the nugget finder website https://www.nuggetfinder.com.au/products A NEW EVOLUTION IS COMING The 12"x8" Evolution will be released in August 2018 AMAZING SENSITIVITY COMBINED WITH GOOD GROUND COVERAGE LIGHTWEIGHT - ONLY 740 Grams More Details and Pictures soon to be released!
  9. Is it valid that the GPZ 5000 is not for the novice detectorist? I have read on other forums, and reviews on websites that sell detectors, that this detector is very difficult to set up and operate effectively, and is not capable of productive use "from the box" -- thus geared for the advanced, deeply experienced detectorist. I ask because when I bought the Garrett ATX I had the means to buy the GPZ 5000, but was intimidated with it due to everything I'd read. Prior to that my use of detectors consisted of the old BFO types and VLF. And am not too tech savvy and impatient with electronics. So, I opted to buy the ATX. But next summer I'm adding to my detectors. Buying at least 2 more, one will be a White's MXT or GMT (Steve's review has been studied word-for-word), and the other ideally a Minelab. If not a GPZ 5000 then the 7000, and if not either then just one new detector.
  10. This question has been posted over on Prospecting Australia website. Wondering if the brains trust here might be able to help - OP over there is not getting much response. I've never used a GPX so I'm not much help. If some knowledge can be shared here I'll post the link over on PA and the knowledge will stay here for perpetuity πŸ˜‰ Thanks. " Does anyone regularly use Specific Ground Balance? How do you find it? Page 60 of the User Instructions says - When moving to a new area the first Specific Ground Balance must be done with the Ground Balance Switch, not the Quick Track Button. Does this mean you can use the Quick Track Button after you've done the first one? I've never used Specific and wondering whether I should have been. Thanks for your help. Cheers "
  11. 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 πŸ™‚ 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 πŸ™‚ 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 πŸ™‚ 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 πŸ™‚ 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 πŸ™‚
  12. 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." ads by Amazon... 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!

  13. 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.😑 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…. A season wrap up, if you will. Since I couldn’t muster up the enthusiasm to do everything in one post I figured I would at least post the good stuff. So here it is – 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 – 36 pcs, at an average of 1 pc per visit. Silver total (coins and other) – 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.… - amounted to 61 pcs. Coming later β€œsomeday” 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.
  14. 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. https://www.ebay.com.au/itm/MAGNETIC-INTERFERENCE-REDUCER-SHIELD-FOR-MINELAB-GOLD-DETECTORS/232594646908?hash=item3627b8a77c:g:8lEAAOSwYGFU0bvu 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.
  15. 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. Video # 1 Video # 2 Video # 3 There are more that I will add later. Cheers Good luck out there JW
  16. I am looking for advice from the GPX Veterans on the forum. I recently acquired a GPX 4800. The stock coil with the 4800 is the 11" DD. I am thinking that my approach to learning this machine should be to read as much as possible about the settings, and log hours detecting. Not really a novel approach. So should I buy a mono coil now, or wait til I get more experience with DD? I have a feeling that at this point along the learning curve I may not even be able to tell the difference. Luckily I didn't get two coils so I don't have the problem of deciding which to use.
  17. I was googling around trying to find a PI detector second hand in a price range I can afford without annoying the wife too much and stumbled across this Minelab GPX 5000 that if I sign up for this site and get their phone app I could buy for $541 USD with free shipping, seems a bit good to be true, I can only assume its a fake, ,especilly seeing its from China? https://www.dhgate.com/product/wholesale-dhl-underground-gold-detector-ground/258982300.html?recinfo=8,103,1#cppd-1-5|null:103:r1719577311 I just noticed in the history of sales of it is a bucket load of Australians and the aussies are also on there giving it good reviews after purchasing it so maybe it's not fake? Puzzled. Surprised Minelab can't shut these fools down.
  18. I have stumbled across an opportunity to buy an old GPX4500, it's one that was made in Australia. There seems to be conflicting opinions of if the new or old one is better, I have read the new one has a gpx 5000 guts in it with things disabled so it runs smoother and ground balances better in hot ground but then others saying they would rather chop off their arm with a toothpick than give up their old GPX4500 for a new one as the old one punches deeper on bigger gold and runs hotter. It seems most people think the new one is better, would I be right in thinking this? I've decided I'll get one either way, be it new or this older one. Thanks

    GPX 5000 Lcd Screen

    Is it normal to see bareley visable symbals at the top of the lcd screen looks like cell and battery markings??
  20. I used the GPZ 7000 in the Summer of 2016 (with yellow ferrite ring) but it had so much ground feedback in my detecting area that I sold it. I found that the ground noise on the GPZ was masking targets over the GPX-5000 running in fine or enhance gold timings. (Damp & salty highly mineralized ground.) Question: Has the latest software update with Locate Patch & Semi-Auto Ground balance helped significantly to handle this type of bad ground feedback? I am considering buying another GPZ 7000 this Summer to try again. Also, I found that the 5000 can match or beat the 7000 on larger chunky gold targets when running the larger coils. (And of course, the GPZ was superior on some specimen gold types vs the 5000.) Here is an air test on a 3 ounce wire gold & quartz nugget below. The 7000 was at maximum sensitivity of 20 with the stock 14" GPZ Coil. (I didn't own the 19" GPZ coil to try in this test.) I mostly ran in Difficult/General or Difficult/High Yield as Normal mode was impossible here, too much ground noise! 3 Ounce Wire Gold Nugget: (air test) GPZ 7000: Difficult/General: 18" Difficult/HY: 18" Difficult/X-Deep: 16" Normal/General: 21" Normal/HY: 23" Normal/X-Deep: 20" Severe: 15" GPX 5000: Fine Gold w/12" NF Round EVO coil: 17" Normal w/12" NF Round EVO coil: 21" Fine Gold w/15" NF Round EVO coil: 18" Normal w/15" NF Round EVO coil: 23" Fine Gold w/19" NF Round EVO coil: 20" Normal w/19" NF Round EVO coil: 25" Fine Gold w/25" NF Round Advantage coil: 20" Normal w/25" NF Round Advantage coil: 26" -Don
  21. I tested the 14x9 evo on a 2.5 gram nugget i was abel to barley hear it at 9 inches is that normal. Setting was general.sens extra mono fixed everthing else was fp except target volume was at 13
  22. Watching his videos it sometimes looks fairly impressive. But his testing methods are limited to some weird coil inside a home lab and seem dubious. The EMI filter is tested outside and seems pretty effective, but many of the reviews I've found online are completely counter to what he shows in the video and generally seem to be ineffective. I've never run into anyone in the US running one of his GPX mods but he told me he's done quite a few for guys here in the states. Is it totally bogus? Anyone out there actually paid for the mods and put some field time in with it? Anyone bought one of those EMI filters?

    Gpx 5000 Question

    i purchased a gpx 5000 , what is the smallest gold expected to find with it? right now i can see a .3 nugget 3 inches away with small 10x5 coil. i guess my question what is the smallest piece should i be able to find and what settings are best, another thing my detector will see .3 of gold it screams .3 of lead it will not register.
  24. I would like some opinions on what my next coil selection should be for my GPX 5000. I have my Vlf unit (Eureka Gold) with 3 coils to cover the smaller gold. Presently for the 5000 I have a 8" commander mono, 11" commander DD, 11" commander mono and a 16" Nuggetfinder Mono Advantage and I would like at least one more coil. I'm thinking to maybe get an even larger mono. Maybe the 22" Coiltek Goldstalker mono, Or the New Coiltek 18" round Mono Elite. But the Coiltek 24X14 goldstalker sounds interesting. Then of course there is the Nugget finder 25" mono Advantage but it's much more expensive than any of the others. On the smaller side there is the 14X9 Blitz said to be developed for the 5000. So what would you all think I should buy?
  25. So a couple weeks ago I was out detecting with my GPX 5000 and all was going well. Steve Herschbach and I were hunting a spot where there are several patches in a comparatively small area a few hundred yards up to a quarter mile apart. At the last place of the day, I took out my GPX and turned it on, and it sounded weird (the 5000 goes through a specific set of tones on boot up and I know what is normal). I looked at the display screen and it was off - it looked the same as when the detector is off. It was making some faint sounds and I waived some metal objects past the coil and it did make a weak sound as the metal went by - but it was obviously malfunctioning and with the screen off, I could not adjust the sound upward even if I wanted. I tried a second power cord and that made no difference. I tried another coil - also no change. So I sent the unit into minelab for repair. They rebooted the unit to all the factory presets and it worked fine. Apparently this happens sometimes that the computer gets itself set to some weird setting and it wont run right unless reset to the presets. Turning on and off is effectively a partial re-boot, while retoring factory pre-sets is a full and total reboot. Sometimes that is what it takes. So, the moral of this story is......... if you find that your Minelab GPX 4000 to 5000 model seems broken, try a different power cord, try another coil (both these I already knew), but also try rebooting to all the factory preset settings. Here is the procedure from the GPX 5000 manual: To restore all Factory Preset settings:1.Turn the detector off.2. .Press the On/Off switch down and hold until the Reset Defaults menu appears (approximately. 5–6 seconds).3. Turn Function Select to the right to select All Settings (as shown on the diagram).4. Turn Setting left or right to restore all Factory Presets.The detector will restore Factory Presets and re-start. Just thought this falls into the category of stuff worth knowing if you own a GPX detector.
