  1. I've personally seen 2 x failures. The first one out of the box would try to start up - the display would start the start up process & then just shutdown. Thought it may have been a dud battery but same thing with another brand new battery. It went back & although it was a pain they said it was a 5min fix. Ribbon cable not connected/clipped on properly between boards due to a new manufacturing process (2 × boards in the 6k - others only have 1). 2nd one probably got about 10-20hrs max. without any apparent issue. We stopped for lunch one day then it kept coming up with a coil error after lunch. Changed it with 3 x other coils but still occurred. Reading between the lines, (I didn't talk to the technician about the 2nd one but did with the first one), it read like it was the same or very similar issue from the warranty repair report? That's just an assumption though. To me it's more of a manufacturing quality control issue & not so much faulty parts etc. Either way it should be better for an expensive detector but can't fault the service here in Australia with both. Good news is both are now well used & fingers crossed no further issues.
  2. Yes it does charge the 6000 batteries. So do other cheaper ones that have the correct plug & polarity.
  3. I haven't had an actual metallic target balance out as yet. I don't tend to keep sweeping over anything I consider a faint or suspect target though (like Steve says some are like an intuitive response rather than a signal response). If I get a suspect noise I'll move to the side a little & do a quick track then re-sweep - in all circumstances I can recall where a signal has remained it turned out to be a metal target of some sort. With that I've assumed any suspect noise that disappeared after the quick track was due to the ground/unsettled ground balance. In a lot of cases I find metal targets can also be a little brighter after a quick track away from the signal. One interesting thing I had the other day on a piece of gold was a clear, bright signal from one direction & absolutely nothing from 180deg (GPX11). Possibly due to picking up better on the side of the coil rather than nose? I nearly walked at one point but persevered for a little sub gram piece. I think this issue has been around in some shape with all auto tracking detectors & the solution is much the same with all where you have no fixed option - limit sweeps over those faint/suspect type targets, quick track/balance to the side away from the suspected target (to eliminate possible ground noise) & then repeat if necessary during recovery.
  4. By using the chip out of the 14" DD coil I'd assume the GPX6000 will then act like you've got the DD on & run in either ground or emi cancel? At this stage I wouldn't "sacrifice" either of the mono coils. They are very good & I can't see that the 10x6 in the videos is finding anything that they wouldn't in most situations. Obviously there are areas where a 10x6 will be better at getting into tight spots though so hopefully Coiltek (or Nugget Finder?) can come to the party with plug & play.
  5. It's certainly an issue that seems more common with this release (GPX6000) than with other recent releases (GPZ, SDC 5k). Thankfully in Australia Minelab service is still pretty quick & good. It has probably dropped off a little but I reckon it's still ok. Minelab & Plexus Inc. really need to have a good look at this + why it's happening. It's too easy to just blame current world events IMO. Maybe Plexus have become too comfortable in their manufacturing contract & quality assurance + Minelab have taken their eyes off the ball a bit? Hopefully it's sorted sooner rather than later cause I believe the 6k is truly a terrific detector that deserves better.
  6. We used to notice that a lot with the SDC in particular. Windy conditions used to cause us no end of frustration some days. Being dry is just a usual Aussie summer & sometimes winter condition (depending on north/south location). I've read a theory on it somewhere that sounded plausible. Electrostatic discharge which can occur due to rapid movement of air near electronic equipment. I'm assuming that this could also occur with coil movement on still days too but just not as likely or prominent?
  7. In the attached video is an example of the tracking being thrown out by the pick. When the second target is found from about 8:10 you can quite audibly hear the ground balance get thrown out by the pick pretty subtly at first then when digging 2 × very audible pick strikes at about 8:40 & then again when he moved it pretty close by the coil at approx. 8:42 to 8:43. He then say "carrying on now isn't it". Les doesn't re-balance or auto tune afterwards & the 6000 continues to be very erratic until the end. I've seen a few comments on that section of footage say how bad the 6000 is with EMI but to me it's pretty obvious that the pick being too close to the coil caused the bulk, if not all, of the erratic threshold.
  8. One thing I've noticed, & it's pretty obvious in a couple of videos I've seen, is that the 6000 hates having the tracking thrown out. In some videos you can see (& hear) where the pick etc. has come too close to the coil while it's set down to search for the target & it becomes erratic. Seen many comments wrongly say that it's EMI. Good thing is it's very easy fixed once setting off again, a quick track & a few broad sweeps seems to fix it up. I guess that's one price you pay for a very sensitive detector. I know I'm a lot more conscious of where my pick is or keeping things like phones out of coil detection range than I was with the 4500. GPZ was similar from memory.
  9. I always use the headphones while detecting & only use the speaker for short periods if showing someone else the 6000 so my experience is based on headphone use. I've had very little issues with EMI in comparison to other GPX detectors. I've used the 6000 with 11" mono in places I couldn't use the 4500/5000 with a mono coil. Air traffic has also been less of an issue with the 6000 over previous GPX's IMO. The 6000 to me seems to settle down quicker or if it does get erratic after EMI interruption is settled down heaps easier & quicker via the auto tune. I'm actually finding mine to be closer in EMI handling to SDC/GPZ, although in similar areas I did find my SDC's could require a number of auto tunes on start up to get stable then more during the day while detecting so in some cases I'd rate the 6000 as better. Edit: Will add that 90% of the time I detect with an old mate of mine & he uses a 6000 too. I keep fairly close to him most of the time i.e. within line of sight. We've not had any major dramas with machine interference either unless getting within about ~20m (60') of each other. I usually get him set up & on his way then set up + auto tune my machine.
  10. For me it's a very minor annoyance barely worth worrying about with the 11" mono at least. I find I like the handle/user interface screen cocked slightly in towards me too so button lock locators would really be a custom set up to suit me. Last couple of times out I took a little extra time at set up to concentrate on tightening the shaft locks up as tight as I felt possible without damaging them & that's worked well for me. I have purchased some nylon shaft button locks but haven't found a need to install them. In saying that I haven't had the 14"DD or 17" mono on all day yet so that may change. Was thinking of buying a whole new shaft assembly to modify so I keep the stock shaft original (as per individual custom mod above) but ATM can't really justify the cost vs this very minor issue.
  11. Bit apprehensive about replying to this. Not sure if it's just a stir or not? Anyhow here's my take on it. I've been around for awhile but not as long as many here. Maybe they've seen more of what I'll try to explain here than I? Originally I started out mostly wet prospecting with pans & an Angus McKirk sluice. After a bit detectors took my interest but I only vaguely remember the GPX4500 release & as I wasn't overly interested then I don't recall any negativity, disappointment or angst & arguments about it all? That changed pretty quickly! I firstly purchased a cheap generic VLF but soon realised that wasn't going to cut it. A Whites GMT soon followed. After cutting my teeth & successfully finding some sub gram bits I was hooked. Research led me to the Minelab PI detectors that I'd seen before but decided were out of my budget to start off. Saving some money & still not wanting to over commit a very nice condition SD2200D was purchased. Again some learning, some gold, lots of fun - hooked in deeper. Reading more about these Minelab detectors & the gold people had found had me intrigued. The recently released GPX5000 was a must! That's about when I noticed it all i.e. it's not as good as my 4500, one more timing & $2k more, this little fold up thing with 8" coil can't replace my GPX (even though it was never meant to), it's too heavy, it's too noisy, I don't think it goes as deep as my old one etc. etc. Have seen it to varying degrees since with the SDC then GPZ releases & now the GPX6000. Point is in recent times I've never seen a Minelab release where people were unanimous that it was a good thing. I doubt we'll ever see it? To be honest I've really thought this one has been one of the tamer releases after 5000/SDC/GPZ? Lack of numbers might be why it's been pretty quiet on the forums in comparison? There was a lot more kefuffle + early sellers with the SDC & GPZ from memory. I've only ever seen 2 x 6000's up for sale & the 1 x swap deal that's up currently? If the swap is about being sick of digging small gold at depth then a 7000 won't fix that! One of those for sale appeared to be more about making some quick cash than anything else - had $8500 on it. There were also some early GPZ's sold soon after release at an increased price due to limited supply & picking up a lightly used SDC soon after release proved pretty easy too. Many didn't like the threshold or thought it was a ladies detector not for real hairy knuckled men (some of them still use their "wifes" detector frequently). I got one within 2 months of release barely used & $800 less than new. That unwanted SDC found a lot of sub gram gold & owed me nothing when I sold it. The lightly used GPZ I purchased (wasn't unwanted but forced sale for other reasons) was sold for nearly the same as I got it for over 12 months & many hours use later. One man's "trash" another man's treasure. IMO performance in these early sales isn't the real reason as a lot of early sellers later jump back in after bug fixes (GPZ) or even just better understanding what the strong points are. Main reasons IMO are disappointment after getting over hyped up, angst at whether a new machines is living up to an old loved + comfortable machine, not having instant success (usually an operator not machine fault) etc. Some will just straight out not like it & that's fine too. No one machine will ever suit all!
  12. Personally the EMI "issue" hasn't been an issue for me? I do mainly use the headphones at the moment being winter here but I'm finding the GPX6000 with GPX11 mono is markedly better with EMI than previous GPX models. Any EMI I have experienced has been easily & quickly dealt with using auto tune &/or settings. I haven't needed to resort to the GPX14 DD at all as yet even though Minelab recommend it for EMI situations. To put this into context the public ground in NSW that holds gold prospecting opportunity is also regularly home to public EMI producing installations i.e. LV/HV powerlines, phone towers, railway, air traffic zones, fences/electric fences etc. etc. that I deal with at least one of mostly every day (if not 2 or 3) I detect. Granted we don't have the amount of air traffic that the USA has but the 6000 to me noticeably handles what we do have many times better than previous GPX's with mono coils. Even private property here has a lot of various man made EMI sources. None of this, private or public, includes the different natural spherics encountered also. I find the GPX6000 up with the GPZ & SDC in these areas with the correct settings etc. Now I'll duck for cover 😮 Reading between the lines + from what I've personally seen with a couple of operators a lot of issues could be attributed to the operator IMO. I've seen a tendency for operators to try to run it flat out in auto+ or manual ~10 in areas you just can't do that with the mono. Less is sometimes more! I've also seen a tendency for those using the speaker to turn it up to high levels or even flat out. All this does is amplify everything - ground noise, EMI, target signal etc. Again less is sometimes more & targets will still be very apparent even with lower volume levels, test some targets & adjust. Some tend to think they'll miss something at a lower volume but have it so loud it just becomes a rude, confusing noise to me. A lot are also confusing EMI with the ground balance getting thrown out. This machine is very very sensitive & large targets or inadvertently getting the pick near the coil can & will throw it out of balance. Very quick & simple to fix using the quick track button in most cases + re-auto tune if necessary. You can audibly hear it happen on a number of videos when digging holes & the pick starts to upset it. I've learnt to keep the coil well away while digging. It seems much more sensitive to this than previous GPX's etc. The sensitivity of the 6000 seems to be taking some getting used to IMO. I think it's great 👍
  13. Video from Lesgold using the soundPEATs aptX LL receiver into a Steelphase enhancer on GPX6000:
  14. I'd say it was a combination of turning on/off a lot (not setting for continuous detecting), using the camera + when it got bad on the second target was after you can quite audibly hear the ground balance get thrown out by the pick when digging & then again when he moved it pretty close by the coil (approx. 8:40 to 8:43). Les never re-balances/settles the machine down after that happens. I used mine with the GPX11 mono (& found 2 x small bits) on an old patch under + near some LV powerlines. Last time out there I didn't get anything with the SDC. Previous GPX models have been all but unusable here with a mono coil unless right away from the lines. I'd originally gone there thinking I'd try the GPX14 DD under the lines but didn't need it. The ground, which is red/orange clay + scattered ironstone & basalt in places, was also heavily saturated to the point of water ingress into some deeper holes while digging. The GPX6000 ran great there & I only noise cancelled 5-6 times in 4hrs (mostly after moving back towards the lines it needed another cancel). Mostly used auto or auto+ but did drop back to manual 5 in one of the more saturated areas due to ground noise & it was also directly under the powerlines. It then ran nicely. P.s. Les has been using a Bluetooth aptX LL receiver to his Steelphase enhancer on the GPX6000 & says the set up works well but I'm assuming it was the built in speaker used in the video?
