With all the newer transmit/receiver style units out there now I was wondering if there was an update for anyone that has made the jump to wireless for the GPX and how it is working out. I have tried two systems so far and not bee happy with either one. Detectnix (sp) unit with their headphones....it worked but there was interference pending on where the unit was located. One video on YouTube showed putting it in a specific spot on the control box and it helped...but still got a lot of signal dropouts and static sound, there is also a delay in audio. I went to a newer low latency Bluetooth dongle and synced my Equinox wireless headphones to it. It too works, but still has the static sound to it. The signal doesn't or hasn't dropped out yet and there is only a very very slight delay in the signal. It is useable but I'm wondering if there is something better out there. I see Gray Ghost has a set of headphones and dongle for the Minelab machines. Also wondering if the Garrett Z-Lynk headphone kit would work well with the GPX. Minelab has the ProSonic but is the most expensive of them all and reviews are not what I hoped to see as far as the GPX goes.

Here is my problem. I bought this used and I know it's older then 3 years and it was working fine. I can hear the threshold but I can't hear the target response. In this case the target is a gram nugget. I have a metal fire pit in my backyard and I have to put the coil about 6 inches from before I hear a response. This problem comes and goes for what it's worth. I have tried different coils with the same results, used those same coils on my 3000 and everything is dandy. On the front panel I have the switches set as Fixed, Double D, Normal, and General. ( I was using Double D coils) I have tried the Factory preset and the problem is still there. Any ideas before I sent this off to Minelab?

Hello all, I am gearing up for a relic hunting trip in the southeast US. I have permission at a nice CW camp, that I used to hunt over 30 years ago with my White's 6db and 5000-D. I think this would be a great place to take the GPX-5000 (nice red dirt). However, a power line runs right through the middle of the camp. This was a minor issue for my White's vlfs, but may be a bigger issue for a PI. I have two AI coils, an 11" and a 14" inch which work great for the EMI which typically occurs around, or in, houses. However, I have never tried them beneath or near a power line. I want to make sure I have a number of options if the AI's do not work. I have read the manual pretty thoroughly and searched the forums and came up with a list of methods to minimize EMI (see Table below). One of the techniques was mentioned by Jonathan Porter in a Treasure Talk article on the GPZ-7000 (link below). He mentioned that "Bogene's Settings" are effective for the GPZ-7000 and have been used in the past for the GPX line for reducing EMI and ground noise. https://www.minelab.com/treasure-talk/using-the-gpz-7000-in-high-emi-conditions-and-audio-smoothing After a bit of searching, I came up with the original thread (link below), which dates back to 2008 and was originally applied using the GPX-4000 and GPX-4500. The method consists of turning down the threshold (until there is no "hum") and turning up the gain and/or stabilizer. http://www.finders.com.au/forum/viewtopic.php?t=3442&postdays=0&postorder=asc&start=0 The technique appears to have been originally developed for very hot ground in Australia, but Jonathan Porter indicates that it can be used for reducing EMI, at least for the GPZ-7000. My question is, has anyone used this method on the GPX-5000 for reducing EMI, and if so how effective was it and what were the disadvantages if any? If this topic has already been covered, I apologize in advance. Thank you!

Daniel Teague Published on Dec 27, 2018 - Took the 4800 to the bad dirt bullet site with the new to me DeTech Spiral 15" coil. Also had the Nox 600 with me with the 12x15 coil too, just to play around with it.

Last week I visited my favorite gold beach and hit an area at the end of the day that produced 5 silvers, a couple of war nickels and 8 wheat pennies. Much better than the limited amount of clad I found the first part of that day. It was posted in the Equinox forum under Equinox and EMI. Today I hit that same area with the GPX instead. Being a holiday, I figured there would be limited train runs, and for most of the day that was the case. I ran the GPX as hot as I could handle and put on the 12 1/2" DD coil to get the most depth I could get. It worked! Had a great hunt. Some oddities for the day included a nice old Ford key, a twisty tie (bread tie) that fooled me for a bit, as it is the brightest gold foil that I have ever seen. Thought I had a gold chain But the oddest thing I found (or actually re-found) was a deep (18+ " ) remains of a Pringles potato chip can. I found it a while back and the chips still looked like the day they were made. I never took a picture of them and left most of the remainder of the can and chips in the hole. Well, today I came across it again and took them home. Unbelievable what they label as food these days! As for the goods, I found 21 Wheats (one wrapped in red cloth from a change purse?), a bunch of silver coins including some war nickels and a W/L half. The best find of the day was the unmarked gold ring. Gold beach gave me some yellow today! As for depth on the coins? Nothing was shallower than 9-10" And 2 of the Mercs came in as a repeatable ground mineral signal. If you use a GPX you will know what faint ground variations sound like, I dug a lot of those today and most disappeared when you took some sand of the top. But 2 of them got louder and I knew I had a small fringe target. What I was surprised at was, that both of those dimes came in at a measured 18". I used a pin pointer to locate them and dug the last inch by hand. I wanted to make sure I did not drop the target back into the hole while digging deeper. I needed to see just how deep this machine can go with no EMI present. I am still in awe of how good that GPX 5000 is. So, a great start to the New Year and hopefully I can count on the GPX/Equinox combination to handle any beach conditions I come across.

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?

Just my opinion...I feel the power cord that goes from the battery to the detector is the weakest link in the whole detector system. You can just breath on the thin metal around the plug prongs and bend it. The factory Minelab ones are super fragile. If you barely bump them on something, they are going to bend. Last week I was hooking myself up to go detecting and the cord end hit the ground. Not pavement mind you...just grass and dirt. I picked it up and saw it had bent it! I luckily had a pair of needle nose in the truck and was able to halfway bend it back in shape to where I could hook it up but I was worried about it breaking. This isn't the first time this has happened with previous GPX models. Anyway...I decided to go after market on the cord. I bought a CoilTek and it came this morning. To my dismay...it too is very thin and came out of the shipping package bent! Why can't they make those things a little tougher!?? Such a critical part that is made so flimsy and cheap. I know a lot of guys go to the Gold Screamer pack and eliminate the big cord all together. I tried one and did not like the sound quality so I went back to the regular setup. I don't even mind being tethered to the battery...just wish the ends of the power cord were beefier. I was at a DIV one year where a guy dropped his cord in the hotel parking lot and he bent his so bad that he couldn't straighten it well enough to use. His hunt was shot because of a small incident.

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.

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

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).

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.

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.

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 ? 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 "

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.

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.

Is it normal to see bareley visable symbals at the top of the lcd screen looks like cell and battery markings??

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

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

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.

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?

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.

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.

Can anyone give me some feedback on a comparison between a GPX 4500 and GPX 5000....

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?
