    Latest News On The QED ?

    They're the ones GB. Can't recommend highly enough -and a good price too!
  2. Hi Jin: The answer to your question is "Yes, but - - - " Gold is heavy and therefore is reluctant to move far horizontally from where it was eroded from its host rock - however, erosion over geological time is multi dimensional. That, in a nutshell, is the complication. The gold we detect may well have shed from sources which no longer exist. - - - all adds to the joys and challenges of prospecting though!

    Hi Whitbey. Here's another QED link: http://www.detectorprospector.com/forum/topic/4255-gold-found-with-qed/ Haven't been prospecting since those finds last year. Too busy farming through a drought ATM

    Well done Lunk. It comes as no surprise that someone with your level of experience and expertise can land a piece like that 👍 Kiwijw: I've said it before, yours will come soon. Anyone with your level of dedication and persistence will eventually be rewarded.
  5. Love your work, Klunker Having begun my electronic hobby career fiddling with the things, I sometimes wonder how much a thermionic valve powered smartphone would weigh (including "A" and "B" dry cell batteries) Okay, I'll get back to farming sheep now - - - sorry.

    Another Tale

    Probably an NLIS ear tag. These RFID devices store information which identify the owner. Although passive electronic devices, it's possible the detectors transmit pulse was activating it. Must try one and see -

    Says it all. Merry Christmas everyone.

    The Reg Wilson Gold Album

    Now you know some of his story Reg ran into Ian a while back, but I haven't seen him for many years.

    Perfect Hunting Season

    Well done! No need to press that "panic" button now - -

  11. That's correct, Jin Higher sea levels meant auriferous paleochannels formed deltas where they met the shorelines of the time. For example, the Murray basin was an inland sea during much of the Tertiary epoch. The problem, however, is the shoreline changed as the seas retreated - and the auriferous gravel deposits moved with it. This means that there is no particularly enriched contour elevation for prospectors to follow. Nonetheless, I've discovered certain elevations are noticeably consistent for alluvial gold. Now, I could tell you, but then I'd have to --- well, you know the rest!
  12. Big coil Jin. The impedance of the windings would need to match the GPX specs (among other factors) for it to work though. At that price I'd personally take a rain check. Tony mentioned that it was not a straightforward coil to make (unlike mono's) with a lot of interacting factors to consider The ground loop type coil is intriguing though, the principle being that you walk around (within the laid out transmit windings) with just the receive coil. Tony and Jim were developing a working prototype when Jim died. Tony tells me the depth advantage is staggering, but he hasn't got a reliable system perfected yet. Nenad probably has more info on the subject:
  13. According to my sources, Nuggetfinder have been field testing prototype coils for the GPZ for some time. These are somewhat lighter than existing coils. I suppose, in relation to aftermarket licencing, the ball is firmly in Minelabs court.
  14. Tony (an old detecting friend) has inherited Jim Stewarts coil winding expertise. They spent a lot of time together in the workshop at Laanecoorie Park experimenting with ground loops, different coil configurations, etc. He also communicates regularly with Rowan (Nuggetfinder) Tony has wound a number of concentric (coplanar) coils for the GPX and demonstrated some of them to me at the Laanecoorie test site earlier this year. Here's one not yet painted: On deep targets this type of coil clearly outperformed (depth wise and size for size) all the other coils we tested. These included flat wound and DD's. Tony related how, using this type of coil he had clearly heard a 14 oz colour deeply encased in solid ironstone (in WA, dug up with a Makita jackhammer) when no other coil he tried could hear it, even when partly excavated. Although we didn't test one on the day, Tony is of the opinion that this type of coil (size for size) will outperform the GPZ on deep targets: So far I'm unable to bribe him into making me one
  15. Right on the money! I've had good success on old deep patches doing just that with an 18" Coiltek DD. Jim Stewart and I found that using DD coils larger than 18" (on SD/GP detectors) gave minimal advantage and any slight depth advantage was outweighed by the inconvenience factor. Apart from the obvious size and weight issues, this includes deep false signals caused by mineralisation when running in "sharp" timing.
