  1. There was a whole video on the new patents he has got for the huge 6m coil that was discussed on this forum. I suspect he is referring to that. Hope it is something different.
  2. Shame that patents are no longer being processed, but that is a separate topic. Can see that you would need to be careful who is allowed to prospect on your claim. Thanks for the info
  3. Just curious why you would pay to file a new claim over ground you already hold the rights to? The placer claim would allow you to prove the lode. Only reason I can see is if you are developping a subsurface mine
  4. A second big question is how useful this will be in really trashy areas of the motherlode. It has potential here to do what more expensive machines cannot
  5. Yeah, the response from those air tests on large pieces were not very deep
  6. I presume you are using the 4500 PI because you want depth. Otherwise you would use VLF with target ID. If you want depth then the larger monos are your coils. Iron discrim doesnt work very well at depth anyway.
  7. I just use a SwissGear 1651 City Pack. They are narrow and small to maintain mobility, but carry 3L bladder and fit my pinpointer scoop, tools, emergency equipment etc. It has been pretty comfortable on long trips, and best of all it is 40-50 USD. I also dont like big bags that carry too much (as then I take too much I dont need).
  8. There are also coil cable ferrite snap on shields, but I dont know if they actually do anything
  9. I use the shield you mention (thanks Aureous) plus Woody's emi filter. Biggest noticable effect was switching from stock battery to aftermarket lithium, and getting rid of the amplifier in the stock battery. That seemed to introduce a lot of noise. After that I was able to run gain of 19 stabilizer 14 in most conditions, which was simply not possible before
  10. Amplifier allows you to lower the threshold on the detector controls, but then amplify with the external amplifier. The effect of this is you can use a much lower threshold but still hear it clearly, and boost the quiet signals that were hidden by threshold to be audible. When combined with emi shielding you can also lift the stabilizer so you hear much smaller signals. The overall effect of this is much greater sensitivity to small signals. In effect you are running the dector using settings you previously could not hear. The amplifier quality is also much better than the one in the stock battery. In my experience it allowed me to go over ground and hear deeper nuggets. But ask the australians, they all use amplifiers
  11. Yes. Get a 15" evolution and an amplifier. Shield from emi and ramp stabilizer and gain. You will see a difference
  12. When looking for new ground I dont dig trash signals. When I have found my indicator nugget I dig all signals. I am not so sure about the price reduction, time will tell. There is still no challenge to the flagship detectors. People buying the new entries are unlikely to have ponied up for the top of the range. Lastly they are not a one horse show. Detectors are not their only business and they may just transition their focus.
  13. True. I initially got a vlf, collected dirt samples from the gullys I detected, then spent about 10 years drywashing before I finally made it back to a PI. The drywashing, however, was invaluable in learning the ground where gold liked to be
  14. I'm with Norvic, the better finds are always in the patches nobody has found, including the oldtimers. They are not near mines and old placer patches. The only way to find them is put in a lot of miles, and be lucky. A lightweight detector makes that a lot easier...it doesnt have to be the deepest as you can bring in big guns after you have found it.
