Each time I try and ground balance my 6000 there is no detectable change. While holding the GB button I pump the coil then move it side to side. It’s like it don’t work. I friend of mine says his does not either. What am I missing? I run in manual mode with the threshold on. The noise cancel works very well.

This is from Steve’s GPX 6000 accessories page. The following items do not come with the GPX 6000, but are likely to work with it based on what is known so far. This is preliminary guesswork, and it is not advised a purchase be made based solely on the information presented here. https://parts.minelab.com/0302-0082-p/0302-0082.htm

How many hours run time are most of you guys getting on a set of gpx 6000 batteries 7.5 for me with no back light

I was pretty excited about this one so I couldn't resist posting the video of it, it's a 12x6" prototype test coil being used on the GPX 6000 to find gold, it found 3 bits on it's first run. This was one of my favourite coils on the older model GPX and if I end up with the new GPX it will be a size I'd have to have. It's long sensitive nose was great getting up between the rocks I regularly hunt in. This is purely for information for those interested in following the progress of the coils. These coils are not being sold by them yet, it's in a testing stage and they will require an adapter which involves removing a chip from the original coil. You'll see in the photo the adapter inline on the coil cable which has the chip in it that was removed from the standard mono coil. And the video The 3 bits of gold found while testing it. The one to the left was the one found in the video.

I run in manual 8 9 and 10 normal ground when in auto auto 2 normal ground this is for northern Calif. When the ground is wet from the rains I switch to difficult ground . With the gpx 6000.. For Nevada with the gpx 6000 do you guys prefer manual or auto sensitivity

I purchased the GPX 6000 from @Gerry in Idaho a few months back and had only taken it out once for about 45 minutes and had to put it away because it was screaming at me due to iron scattered everywhere. Fast forward to this past weekend, I went down to Rye Patch to @Gerry in Idaho's training to really get out and try this thing out. I ended the trip with 8 pieces totaling 3.7 grams, cleaned. The biggest piece was pretty cool so I am including pictures of both sides of that one, 1.5 grams cleaned. All 8 were found right around the burn barrel area. Thank you to Gerry and all of his staff for a great time and knowledge! @Lunk @afreakofnature and the rest of the team.

Went to some old dry wash workings under powerlines to try out the 14 inch coil. This little guy was hiding just beneath the desert pavement near the old workings within 30 ft of high voltage overhead lines. Over the course of a couple hours dug multiple trash targets including small lead shot. Not the easiest coil to pinpoint with, but small targets in high EMI impressed me. Desert north of Yuma. Mike

Hey Guys, Well its that time of year where most of the US Prospectors are searching for gold, in the Southwest at least. I managed to get out this weekend with some friends, just roaming around some old stomping grounds in hopes to turn up a few bits missed years prior. I was toggling between my GPZ 7000 with the NF 12" coil and my GPX 6000 with the 11" coil. My other two friends were using the GPZ 7000's with the stock 14x13" coils. Later in the day I can across some old piles left from prior mining and got a softer sounding signal and decided to investigate. My friends both had a few dinks now, so I was behind on the gold count. There's a lot of left behind rubbish in this area due to prior mining, hardrock and placering. I figured it was just another deep nail or something, but as I got down deeper, the target was actually on bedrock below the pile. I ended up scratching everything away from the bedrock and pinpointed the target in a crevice or depression (seen in picture below). Low and behold, it was a nice gold nugget, 4.6 Dwt's, just shy of 1/4 Troy Ounce. I was pleasantly surprised to say the least, didn't expect it. I thought this would be good time to see if my Minelab GPX 6000 would hear this target with the stock 11" coil on it. I walked back to my truck, got the GPX 6000 and hiked back to the target location. I figured this would be a crude, but interesting test as there is so much debate on depth and how now many believe the GPX 6000 is better. I fired the GPX 6000, balanced and make sure the EMI was good, then scanned over the target area with the nugget back in it's original location. I couldn't hear a peep of a signal, which honestly is what I figured. I didn't expect to find it, or hear it with the GPX 6000. I played around with a few settings and even had my buddies come over to check it out. They both scanned their stock coils (GPZ 7000 with 14x13") over it, both heard the target, but it was still faint (not a super obvious signal). This is one reason it's hard for me to put down the GPZ 7000, I have found many nuggets at depth, but deal with the heavy, bulky unit. I thought about going back and trying the 14" DD to see what it would have done, but for the most part, I never use the 14" DD, so it wouldn't have really proved anything to me, as I don't use it. It would have been interesting to see what the 17" coil would have done, but I didn't have it with me. I would think the 17" would have heard it. I'm swinging the GPZ 7000 with the NF 12" Round coil 90% of the time, the GPX 6000 about 10% of the time. There are some bedrock gullies I have revisited in years, so I'm looking forward to spending more time there with the 6000 and 11" Mono coil. I think I also might be able to pack the GPX 6000 into a few canyons as I wasn't easily able to do that with the GPZ 7000. Here are a few pictures below. I didn't have a tape measure, but Doc's pick is 22" handle length. I'm thinking between 18-20 inches was the true detection depth, but faint signal for sure.

Who has run the sp01 on their 6 I had a crack , with my cogs as well , but found the cables a pain in the arse ... Also with the 6,s headphones on 70% volume on the phones and the detector backed off a tad I hear the feint murmurs ok I reckon anyway ? I

I'm checking both out. Need some input by others.

Does the 6 eventually ground balance out a faint target that repeats from multiple directions in the beginning....like the GM1000 will do in auto? I run the 6 in manual mode 99% of the time..... This one area I've been working off and on lately has me frustrated because I've had quite a few faint repeatable targets that I end up walking away from because I loose the target and move on because time is too precious. My thought is that SOMETHING set the machine off....so something is there and I can't even seem to dig up even a hot rock or whatever set the machine off? It's driving me nuts trying to figure out WHAT is setting the machine off? I've dug many tinys with the 6 and currently at 98 nuggs with the 6 but this one area has me baffled with my walking away from several targets? Only this particular area has me scratching my head....I do ok anyplace else. Here's todays 5.5g nuggs despite the frustrating disappearing targets thingy.... Thanks for any input.....!!!!!

Is there or has there been any comparison testing done in the field on depth with the 6000 vs the 7000 using the NF 12" Z-search coil. Thanks . . .

There seems to be some kind of update to the 6000. I haven't had time to read through it all and doubt I will get the time because I'm swamped with non-prospecting stuff. But I noticed a new FCC filing on the 6000 related to something along the Bluetooth lines last week, I can only hope it helps the EMI issues but I have zero idea.

I have no problem with coil twisting and I am using the 17” now. I think people who are having a problem are not tightening down hard enough. The shafts are carbon fiber you’re not going to break them tighten the clamp as tight as it can possibly get. If you’re just weakly tightening it down then you are going to have some twist. Quite honestly if you wanted to drill a hole and put a pin in yourself it would not be a big deal but I think it defeats the purpose when you want to tighten up the cord by giving it a twist before engaging the locks. So far I’m satisfied with it. Keep this in mind to if you think you can actually tighten it to the point where you’re going to break it it’s under warranty for three years! But if you drill the hole it’s probably not under warranty anymore.

The GPX 6000 has 3 coils which are all large. Does anyone plan on making a smaller ellitical coil for getting into tight areas ?

Early wet Weather in Northern Nevada, sure messed up a few of my hunts! But, this last Hunt was called Rain or Shine! Be there or miss out with the original hunting party. We had half the amount of coils on the ground during this hunt and managed to find a few sweet spots of dinks to add to our pokes. Rain on us with snow in the ground 200’ above us all 4-Days! 6000, Retune Button got a workout. I kept the 11” Mono on. Tried the DD for a few hours with no luck, don’t know if the ground and line I took was bad, but the guys behind me where finding nuggets…so back to the 11”. My truck is out in the drive way in the wet Weather still loaded up with me gear! Getting wet again to unload it, I can’t wait ? Until the next Hunt! LuckyLundy

Probably the most educational one in awhile too. ?

After reading all items available I am confused. It's probably just me so I apologize if this is a dumb question. In soil that has low mineralization which coil will go deeper and is more suitable, a DD coil or a mono coil of equal size? Or in low mineralization does it not matter if you use a DD or a mono coil? Bill

Is there or has there been any comparison testing done in the field on depth with the 6000 vs the 7000 using the NF 12" Z-search coil. Thanks . . .

I haven't seen very much conversation about the comparison between these two detectors now that the GPX 6000 is creeping into the SDC 2300's territory. So far, the GPX gets both smaller and deeper gold. Has anyone other observations?

Yes I finally did get a chance to hunt for larger gold with the GPX-6000. This video has some quirks and I am sorry. Shooting video is not my expertise as you can tell. Error #1 and many of us do it. Keep the phone Horizontal (left to right) to get full size viewing. Error #2, be sure to have someone else shooting the video while holding camera Horizontal and not shaking as much. Now for the bit of info that many of you may have missed in this video. I won't reply with answer yet, but will give a hint "sound". So yes a get a little excited and yes I mumble and stumble for words. Heck I sometimes freeze up and slowly look around to make sure nobody sees it or me. I have heard other do that as well, why? What would you do?

as I already put in another post, I just bought a second-hand gpx 5000. It comes with the comander 11 DD and 11Mono coils. I would like if it is possible for a colleague to recommend a coil to complement the ones it brings. Its use would be to search for coins. I've been looking at the detech 15 inch DD ultra sensing. If anyone has used it, what can you tell me about it?

Has anybody done a quick air test on a U.S. Quarter or other large target with Normal vs Difficult Timings? I have tested Normal vs Difficult and found that Normal is not deeper than difficult on large targets. (Manual 10 or Auto +1 Sensitivity) I also get very broken or confused signals while using Normal at fringe depths while Difficult gives nice & clear high-low signals. Do others notice normal timing giving greater depth on large targets over difficult timings on the 6000? (There may be something wrong with my 6000. In addition to Normal giving zero extra depth for me, I have received an intermittent "coil error" with both the 11" & 17" mono coil. This usually happens after using the machine for some time in the field and once it starts, it won't stop even with a full factory reset. I have the machine scheduled to go back to Minelab and I am hoping they can reproduce the "coil error" fault I keep getting.) -Don

Hi there, Looking at getting another detector for the Golden Triangle in Australia. Have a vlf but looking at either a new sdc2300 or a 2nd hand gpx4500 for marginally cheaper. Which one would better to learn PI with, and which one performs better? Cheers

I've been reading about DD and mono coils for the GPX. I'm confused
