  1. 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?
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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!
  7. 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 👍
  8. Video from Lesgold using the soundPEATs aptX LL receiver into a Steelphase enhancer on GPX6000:
  9. 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?
  10. + 1 on that My local areas here can go from mountainous, rugged terrain to steep gullies to wide open flat areas. There's a huge variety of ground conditions & topography. The 6k seamlessly handles it all with the ergonomics making it easy to use in different terrain to boot. I don't disagree with the GPZ7000 still being the top dog but personally for me, here in NSW Australia, the GPX6000 is making it seem unnecessary & cumbersome for a lot of my detecting areas. Just my opinion.
  11. I don't see the issue? I've only seen one dealer asking for deposits on the GPX6000 & the rest were expression of interest lists. I voluntarily paid a deposit on mine knowing full well there was no firm release date & was prepared to wait. My aim in paying a deposit was to secure a GPX6000 within the first few batches released. As it turned out my deposit secured mine on the day they hit the dealers shop. I had put my name down on 3 x expression of interest lists prior to putting the deposit down. Without a deposit only one of those three had contacted me in regards to actually purchasing an available unit, one contacted me to attend a demo day where it would be available to look at but not buy & one has never made contact. IMO putting a deposit down on something sets you aside from others who may be just tyre kickers & not 100% sure if they'll purchase or not. There are a fair few consumer items that you won't be able to purchase without a deposit but they do usually have delivery estimates. It is common with furniture, new cars etc. in Australia.
  12. The original Saturn Pro's are switchable between tx/rx & you can buy as a pair or single. The link is for a single one. Have seen them cheaper but they are hard to get now. Not sure why Avantree moved away from the single switchable tx/rx units or that compact design?
  13. "Your shafts are already working loose after a couple of hours ? Lets see how they are going in a few months, or a couple of years !" No they sometimes do & not to the point of flopping around loose. It might rotate slightly like 5-10deg. if that. Mine doesn't flop around or anything like that. It's barely noticeable & only minorly annoys me because the user interface isn't symmetrical with the coil (overly attentive to detail disorder I think). Norvic has it nailed in that it's more the top clamp which can be difficult to fully tighten due to the coil lead. I'm sure we'll work it out. Mate I wouldn't put much stock into the "user" reports thus far. Long way to go yet. I can remember experienced prospectors who shit canned the SDC & GPZ too! One took a SDC for a test run & complained that a $4k machine had no noise cancel - should've read the manual first. The list can go on & on. Many sold the GPZ quickly!
  14. The plastic isn't soft IMO? The tape is there to prevent marking on their shiny new toys. It is a high gloss finish on the coils & marks/scratches stand out over other matt or textured coil finishes I've owned. I haven't taped my GPX6000 coil but in the past have used a clear cover or tape on some coils to prevent marking. Tape would only be a bandaid solution to that amount of wear if it were occuring. Mine isn't wearing unduly & neither is the skidplate. I'm a coil scrubber too although I do go fairly lightly. Plenty of GPZ users attached perspex covers with velcro & tape to the tops of their coils to prevent marking too. My GPX6000 shaft is also fine & the clamps are locking fine. Over a few hours they sometimes work loose & the shaft moves slightly but it's like a 20sec fix & away you go again. A big non issue on mine. The GPZ shaft clamps have also been known to fail too. Not good for a $10k detector IMHO? Rick you seem to have your nose out of joint over a detector you repeatedly (on a few forums) say you have no interest in getting? As a user I would say that it has the least amount of annoyances or minor issues of any detector I've owned SD/GP/GPX/SDC/GPZ/QED.
