  1. 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 “someday” 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.
  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. 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.
  4. 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
  5. 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.
  6. 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.
  7. 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??
  9. 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
  10. 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
  11. 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?

    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.

    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.
  14. 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?
  15. 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.
  16. What would be a Fair price for a nice GPX 4000 with control box cover, signal enhancer, 3 of the small batteries for use with enhancer and a charger, and 3 coils, a new 10" Commander DD, a 7"x14" Nugget finder mono, and a 6"x8" nugget finder mono? Thanks for any replies and info.

    4500 Vs 5000

    Can anyone give me some feedback on a comparison between a GPX 4500 and GPX 5000....
  18. What I see with Minelab is a company that misses a lot of opportunity to make money, making a solid cover for the 11" coil would cost them about $2 to manufacture in Asia, and they'd sell it for $30 and there is already big demand. They seem to miss a lot of opportunities like this, it's lucky I'm not a shareholder, I'd be complaining I've had stuff manufactured in China before, it's easy to organise and within 2 weeks I could have a big box of them ready to sell, I would consider doing it if we weren't go geographically isolated from the main markets. I won't be running mine at full straight away, I will learn how to use it first, once I've got the hang of it I'll give it a go as I know it will improve my recovery rate. It's starting to get too cold to hit the creeks with my sluice now so I'm going to have to start dedicating my prospecting days to my detectors, which means leaving the water!!! a big step for me I was so impressed you found stuff with the EQ800 that the GM missed so I had to have one, Dan at DredgeNZ has been fantastic in helping sort that out for me at the best price available and is going to help price wise with a 4500 dual coil pack too, is this the one I would need http://www.dredgenz.co.nz/detectors/minelab/minelab-gpx-4500-dual-coil I like I can use the EQ on the beach and in the fields too for a bit of jewellery and coin hunting and it be outstanding for that. At least I can currently get a higher end style coin hunting detector. The Gold ones are just so darn expensive. I have to work on fixing my boat up this weekend so I doubt I'll be prospecting, I'll wait until I've got my Eq800 next weekend.
  19. I bought a used Gpx 4500 with a 14x9 NuggetFinder coil. I was able to take it out gold hunting yesterday. I was unable to find gold, but was able to find lead at surprising depths. I also found an fragment of paper thin metal about the size of a marker tip @4”. The detector worked really well until the end of the day. It seemed that I was unable to ground balance in fixed mode and or tracking mode. I reset all the settings to FP and retuned. I still felt that the detector wouldn’t ground balance. Is the green ‘ground balance’ track button a simple’ switch that can be tested with a volt meter? Or is there a way to test the button?
  20. The reintroduction of the Minelab GPX 4500 with two coils for only $2699 has in my opinion shook up the price/performance question. Up to now I would have considered the GPX 5000 to be the default "safe choice" for anyone wanting to get into serious nugget detecting with a proven machine. However, there is not a lot of difference between a GPX 4500 and GPX 5000. It really boils down to the Fine Gold timing which the GPX 5000 has and the GPX 4500 lacks. That timing is very good at handling certain very hot ground and extreme hot rocks while still getting a majority of the gold. However, the timing is not perfect and it does miss nuggets or exhibit "holes" in its ability to find nuggets and therefore should only be used in ground that requires its special ability to ignore hot rocks. Too many people rely on it as an "everywhere, all the time" mode. Most ground in the United States does not require the Fine Gold timing. With the GPX 5000 at $5795 with 11" round DD and 11" round mono and the GPX 4500 currently at $2699 with 11" round DD and 15" x 12" mono coils I am hard pressed to say the GPX 5000 is worth $3000 more just to get the Fine Gold timing. Yes, there are other subtle differences but seriously that is what it sorts out as from a practical standpoint. That being said I have added the GPX 4500 to my equipment roster at Minelab GPX 4500 Gold Nugget Detector and updated my Nugget Detector Review to reflect my opinion that at this time the Minelab GPX 4500 represents the best value for somebody new to high power pulse induction nugget detecting and wanting to get in on it without mortgaging the farm. Now, this is based on MAP (Mininum Advertised Price) versus MAP price for each detector. Package deals can be had and may sway the equation somewhat back towards the GPX 5000 for overall value. But no matter what if buying new you are going to lay out a lot more money for a GPX 5000 than the GPX 4500 and it mostly comes down to how much you think that Fine Gold timing is worth to you.

    GPX 4500 Mods

    Are mods on detectors like the GPX 4500 really as good as all these Youtube videos indicate? People are saying they're better than a GPZ-7000 after modding like this video It's probably just wishful thinking on my part as there is NO way I can get a GPZ-7000 but I'm in the market for a 4500. I vaguely remember John (kiwijw) saying he's got a modded 4500, older mod style no doubt to the one in the video but he obviously knows his stuff and got his modded. I would appreciate people who have got theirs moddeds thoughts on the mods, and baffles me why if these mods are so good why Minelab doesn't just adjust their detectors to have these sorts of mods from the factory. Make a GPX 4500 v2 and sell it and make even more money. I've also been told older model GPX 4500's aren't as good as the newer ones, is there a year I need to look out for when they started to improve? Some of the 2nd hand 4500's I have seen for sale have mods, so before purchase i'd rather know if I should avoid modded ones, or certain mods or just get a certain year or whatever, any help appreciated. Thanks
  22. I have hunted this site. Actually dug over 100 nonferrous out of using Deus. Folks told me they had been hunting this site hard since 1975. I haven't hunted in a while. Based on the trees in background and listening to the one gent talk, where the gold was found, ,when I hunted a few times was in pretty tall stubble. I have hunted with the gray haired gent once in Ky. He was a big time CTX man. Notice what he's running now in this video. Also notice how deep the holes dug are. I can attest personally soil in this site 3 bars on F75. Now I mentioned gold found. Not what you think. Cheers and enjoy the video. One heck of a find!! Big congrats to Jeff. Never have met him. Wonder what the rarity value of the find is?

    Detector Mods

    Anybody had modifications done to GPX 4500 by "Detector Mods"? reviews appreciated, wondering if it's worth the $2200.00.
  24. Hi everyone , I am new here , I joined this forum hoping to find some tips and guidance on gold hunting because I am really confused , frustrated with so many information and resource on the net , and I dont know from where to start on how can i be a really a gold hunter . Background : My Journey with gold hunting started in 2010 , when I heard from a close friend of mine that there are gold in sudan ( I am from Yemen by the way ) so I decided to give a try , so I bought GPX 4500 at that time it was famous gold detector device + I bought the big circle coil to give me more detecting depth . Why I went for this trip : 1st : Get Rich , 2nd to having fun and go on an adventure . 6 months past , we were expecting to find 1 kg gold at least to cover at least our expenses on this trip , but we found 180 Grams in total , it seemed like we were out of luck may be because we just rushed things up without guard our self with knowledge about gold prospect , we just used the experience of people who went on this trip before and good guy who program the device for us . And that is how round 1 ends in 2010 . What kind of advice I am seeking from you guys , I am looking for that advice which comes from experience : I am going back for round 2 in 2018 , I have my old GPX-4500 device unsold and before going to Sudan again I need to start fresh this time I needed to gain some knowledge on areas such as: 1- What book / blogs should I read to start my gold hunting education ? 2- Should I sell my old device and buy another one ? 3-How to tell if the device find gold from the the sound it produce how to tell the differences ( talking about GPX 4500 ) , this question is connected to Q Number 2 ... I hared that low sound means gold , high means steel .. I have experienced this myself before , but I think it is just 60% true , I am not sure though , need your input on this . 4-How to tell if one area has gold ( with 10 - 20 % chance at least ) and it is worth the time to spend on searching , geologically before going for search ? Do I really need the help of Google earth to scan the place ? 5-Is it true that only places where people find gold is the best place to find gold , what about exploring new area ( this question connected to question number 4 ) . 6-Is it true that long range gold detector are fake ? Please see this link for more information : http://raregoldnuggets.com/?p=5095 7-When gold detector will fail to find gold ? 8-Do advice me to try looking for gold in the Nile ? Thank you for reading my post and I am looking forward to hear from you . Khaled
