GPX 6000, Anyone Tried It Yet In The Worst Ground?


Recommended Posts

Thanks for the information, both of you.

The 6000 will yodel just like any detector near power lines until you put the GPX14 DD coil on, then it defaults to Cancel mode and it is pretty much hush quiet after that unless you use the inbuilt speaker.

The inbuilt speaker itself causes EMI interference with the 6000?

I have been using my SPO1 and GOG headphones so haven't tried the speaker much.  Gee thats no good, cheers for the heads up.

I get a smoother threshold using the Headphones.

I asked the question and appreciate any experience people have with the 6000 in areas with Really Bad black sand and high numbers hot rocks of small size down in the ground.

Mr. I Brake, Don't make assumptions, I found a .9 Once Nugget 6 inches down in that area years ago, in an 8 inch round hole on bedrock, with enough black sand in the hole to make multiple 3 inch black balls on the magnet I have on the handle of my digger. My Whites GMT gave Magnetic Iron readings in the 70's, and initial Probability of Iron at over 70%, But it was a Good strong signal, and knowing high black sand can effect target I.D I dug it..!

The purpose of asking the question was to get input as to if the 6000 would likely do better in bad ground, I suspect that at least smaller nuggets in the area are BEING MASKED by the Black Sand and Small Bad Hot rocks.

JP would you say it's from the speaker causing EMI though?

I've only got limited time on the GPX6000 yet but also found that the headphones sound smoother. I thought that the speaker sounded a bit "overdriven" which caused the threshold to sound rattier i.e. it seemed very loud even in low volume settings (was a pretty quiet day too) with it's limited volume range from memory when I did try it? I guess people have been asking for inbuilt speakers that are loud so that's what we got 😜 I didn't really notice what I'd say was more EMI type noises?

For mine the headphones are smoother because you seem to have a lot more range in the volume? I set the detector on only the second volume bar then had the headphones set at around half way. I found that plenty loud + smooth enough for me. Turn the detector & headphones right up & you get the same "overdriven" effect?

Plenty of scope for those who use boosters/amps/enhancers to get even more range out of it but I don't think you'll be needing them for straight out loudness.

The "breaking up" you're hearing is probably the amplifier circuit distortion.  turning down the volume is the only way to eliminate that...A distorting amp will eventually overheat the voice coil inside the speaker and cause permanent damage to , and possibly total failure . And YES I have learned this the hard way on a major scale !. LOL but I wasn't laughing then....

- Or high volume speaker coil inductance affecting the detectors high gain receive electronics?

OK , guess it could be possible !  ( my area of experience here is primarily pro audio,,,+ tron school.. )  thx for that clue  , makes sense  . Speaker is a long way from pickup coil but real close to the controller circ ?

I really the fact that the 6000 has such a good speaker system as i wear earbuds and not headphones so i would do just fine without any thing over my ears or in them .

      Dear brothers, I did not find any clear review comments regarding the Minelab GPX 6000 detector My question is, has anyone tried the GPX 6000 and it turns out that it is able to find more gold better than others?

      Hi all, just found on Gumtree Aust a Minelab GPX 6000 for sale. Only the box in the picture. Listed yesterday by Shawn Gib from Sydney. Asking $9000.
      Says your beating the que price is firm. Does anyone know who this is? I take it is a fake so be aware, or someone has one from a dealer? cheers sturt

      Firstly my thanks to the guys at Coiltek.
      After dreadful weather here in central Victoria, and recovering from surgery, this morning dawned clear and sunny. Nice hot coffee and before the dew was off the ground I had the 6000 cranked up. Rudimentary reading of the manual the previous day saw the new detector humming sweetly after a short warm up. JP had been most helpful with a few tips on the local Finders forum, so it was quite easy to feel a certain amount of confidence as I ground balanced and paired up the headphones, which are surprisingly good compared to some of Minelab's previous offerings.
      There is a shallow but substantial lead running west to east across my fifty acre property which yielded a small amount of gold to my GPZ a few years back. I had gridded out the most promising area at the time, so it seemed obvious that this would be a good place to test my new toy. Not bothering to take a pick I headed off towards the east end of the block.
      Where on earth did these signals come from? A number were I am sure just shotgun pellets, but a few were at a reasonable depth as I tilted the coil to get some idea of just how deep. The more interesting signals I marked with boot scuffs and will check out within the next few days. I did not get to go back for my pick as a visitor turned up to have me check his detector.
      Initial impressions; Pretty damned good.

      Six Thousand dollars to put out on anything is a large investment to make .
       I just wonder how many of you have committed yourself to buying the 6000 already?
       I’ve had a long talk with one Minelab dealer and he has been told that the 6000 may slow in coming to the US because of the high volume going to other countries. That’s due to the gold rush is there not here.
       For you that live in gold country it may be a easy discussion but for those of us  that don’t we may have to think about it a while.
       I myself don’t have a bass boat parked in my drive with a big motor and trailer so this year I’m going to be good to me .
       I will have a 6000 as soon as I can get  my hot little hands on one.
       How about you is Santa going to come early?
       The Best!

      8 grammer found at 11 inches.  Nothing special as most detectors PIs should see something that big at that depth, but at least we get to see a big one finally found on film.

      I don't know how many 6000s are already 'in the system' as complete units in the box ready for use but the Covid count in Malaysia is forcing them to shut down some things.

      Be prepared for a long wait with the chip shortage.
