  1. Somehow a metal plate found its way into my EGR a while back, I've no idea how that happened- :)
  2. Not getting one either. Been having far too much fun on deep tiddlers with the Z and X Coil concentric to justify the investment.
  3. Yep. Easy one. Once the big gold ran low in the 90's, John sold his gold and specialised equipment, took the money and ran - :) Acting upon advice from friend Jim Stewart, he wisely invested it in tourist parks along Victoria's "Shipwreck coast" I haven't seen him for a couple of years but looking forward to catching up with him eventually -
  4. And that demonstrates why air tests are useless. Goldfield soils block signals.
  5. Pardon my spelling, Shouldn't type when tired, but that's when I have the time! My most recent understanding is that my friend Ilya and Alex (who I don't know) now control X Coils and market separately through their respective websites: Ilya's website: https://www.x-coils.net/ Alex's website: https://www.x-coils.com/ Of course this may have changed recently-
  6. I guess I spend most of my detecting time chasing gold on granite. Sometimes this gold is miles from the nearest reef or other existing source. As you no doubt know, this gold is left over from the granite pluton emplacement process. For others who may be interested, as the vast granite plutons once pushed their way upwards through the overlying metasediments, they mobilised gold formation in this rapidly thinning and eroding capping. Eventually this sediment capping is almost totally removed by erosion (except for occasional isolated metamorphic "roof pediments" as they are called,
  7. Jin: I'll be looking for different targets with the 26" The big loops were excellent at locating very large pieces (10 oz plus) at good depth (3/4 foot or more) I doubt they missed many, certainly not on the ground I've followed up on ever since. They were less sensitive to smaller pieces (ounce or less) at similar depth, and it's mainly these I will be targeting. The big CC's also punch deep but, due to the narrow field at depth, you need to be almost exactly over the target to hear it. The DOD (and monoloops) are far more forgiving in this respect. Out of interest, the l
  8. - and an SDC as well Trent. One coil type does it all? Hopefully, I'm going to trial a 26" Z DOD spiral soon on deep, unpushed big gold ground,, just to compare results with the 22" Z CC.
  9. Thanks Gerry. Back home now. I ended up with a couple of ounces more than I left with, so covered costs at least: Largest piece was this stained 22 grammer in noisy tertiary ironstone conglomerate, a clear target signal: Find of the trip award goes to Reg Wilson for this 6 grammer, located at depth with a 4000 running "Normal" with "Bogene" settings: This 6 grammer from "Ravens Patch" Longbush near Moliagul was a personal favourite, especially as many consider the area well and truly "skun" Following the rains, mobilised soil salts rendered GPZ "Nor
  10. Good to see you're now an x coil supporter JP. Since over 70% of my deeper finds so far made in "normal" timings could not even be heard in "difficult" I'll just continue as I am, since detecting a large area twice has little appeal. Of course I am sometimes forced to use "difficult" by ground conditions but do so reluctantly in the full knowledge that I'm leaving gold behind. On Tertiary gravels (which are usually very quiet) "normal" timings give maximum depth on all targets and are my favourite and most productive haunts. I stand by my test results which indicate CC coils le
  11. Jonathan: I'm not doubting that hole exists on "normal" setting with conventional GPZ DOD coils, but, as stated, our exhaustive tests with the big 22" GPZ X Coil concentric failed to reveal it. I understand you have access to the 17" X Coil concentric. Have you also tested it for holes? You may be in for a surprise :)
  12. Geoff: It's my understanding that the Z concentrics have twin active central windings (as do the DOD standard coils but a different layout) The coil internals are a trade secret. But an x ray would be revealing -
  13. Mitch: Reg is swinging a Detech 18" concentric on his GPX As the illustrations posted show, you have to be over the target to hear it (big surface junk excepted) Therefore it follows that only the two central windings receive, so my 22" coil is in reality only an 11" one (approx)
  14. No NE, I'm happy my settings got all that was available on the ground I have covered. I have done exhaustive tests on the Maryborough and Laanecoorie test sites with Tony Honey (who has had long experience with GPX concentrics) as well as undug gold targets in situ, I'm satisfied there are no "holes" in the settings I am using.
