jasong Posted May 30, 2022 Author Share Posted May 30, 2022 What Simon said. That subject got discussed to great extent already here years ago. 1 1 Link to comment Share on other sites More sharing options...
GR Guy Posted May 30, 2022 Share Posted May 30, 2022 25 minutes ago, phrunt said: The chips are in the coils, not in the detector, the detector itself seems safe from counterfeiting, although there are fake GPZ 7000's under the hood they're not fake GPZ 7000's and just poor performing detectors, with the easier to clone detectors like VLF's there are fakes that are virtually identical in performance, with I would guess worse build quality. So the aim of the chip on the GPZ coil cable, and inside the GPX 6000 isn't to prevent Chinese from making fake detectors, it's simply there to prevent coils being made by anybody outside of Minelabs control. Don’t get me wrong in a perfect world it would get great all these options. But you can’t say in one breath that counterfeiting exists of a metal detector and then say the coil is off limits though. I’m pretty sure Minelab would put a fair amount of work into their coils as well as the other hardware in a product. 3 Link to comment Share on other sites More sharing options...
Aureous Posted May 30, 2022 Share Posted May 30, 2022 I just spoke to a coil technician and he advised me that the current 6000 coils are the same specs as the old GPX coils....so if the chip could safely be extracted from a 6000 coil and a 5000-6000 adapter made up, then you SHOULD be able to run any previously made GPX coil on a 6000. I feel an experiment coming on... 7 Link to comment Share on other sites More sharing options...

They have only ever been adequate! Why do you think aftermarket companies like Nugget Finder, Coiltek and now X Coils have done so well ? It's because they make good coils.

phrunt Posted May 30, 2022 Share Posted May 30, 2022 Thanks again Aureous, Chet came out some time ago saying the older GPX coils would work on a GPX 6000, that guy seems to really know his electronics. I guess it is something that needs to be tinkered with and accessed. If it is the case that'd be a game changer for the 6000, someone could start a business just making adapters for people and make a fortune. 5 1 Link to comment Share on other sites More sharing options...
jasong Posted May 30, 2022 Author Share Posted May 30, 2022 I was just literally writing something to the effect of "I'm curious what Chet thinks about making some 6000 concentrics and if performance increases are possible or not worth pursuing on the 6, right as you posted that. 😁 4 1 Link to comment Share on other sites More sharing options...
Popular Post Chet Posted May 31, 2022 Popular Post Share Posted May 31, 2022 The GPX 6000 11” and 17” x 13” Mono coils have the same electrical specifications as most previous GPX series coils. That is; the inductance is close to 300 microhenrys (uH) and the direct current resistance is close to 0.3-0.5 ohms. And shielding appears to be similar. The GPX 6000 Double D receiver coil is different from previous GPX series Double D coils. I could not get a DC ohms measurement across the receiver coil. It appears to have a capacitor in series with the winding. Small existing GPX aftermarket coils using some type of adapter/dongle will probably work great. The GPX 6000 works great on small shallow gold by having a fast recovery and processing time for short time constant targets. There may be limitations on large deep gold using large existing aftermarket coils. The GPX may be designed with overall power and sensitivity limited near the GPX 5000 performance. Concentric coils could certainly be developed for the GPX 6000. It would require much development and testing of various sizes to hit sweet spots in performance for different nugget sizes and different depths. Concentric coils for the GPX 6000 will need to demonstrate an overall performance improvement or specific niche in the midst of the other coils to make profitable sales. 8 2 Link to comment Share on other sites More sharing options...
jrbeatty Posted May 31, 2022 Share Posted May 31, 2022 Pretty sure the X Coils guys are waiting for the 8000 release like everybody else. In the meantime they're unlikely to bother with commercial coils for the 6000. So if Minelab haven't yet got the message and fail to release CC's for the 8000, I'm pretty certain I know who who'll do it for them :) 4 1 Link to comment Share on other sites More sharing options...
