  1. New Fisher F-Pulse Pinpointer

    The question to be is it performance comparable with the Garrett pro pointer and at what cost.
  2. Free Book - Gold Prospecting With A VLF Metal Detector

    Love the information in the book. A lot to take into consideration before heading out.
  3. Looking For Jewelry With The Super Pulse

    Short update is in order: Careful study has indicated the depth of the 8 x 14 coil and the 7 1/2" dual field coil is about identical. As stated above the coverage and pinpoint of targets is excellent. But I caught myself swinging to fast not a good thing in bad ground. Even though the larger coil gives better coverage I tend to prefer the smaller coil. I can understand how a hunter can get in trouble with multiple targets under the coil at the same time. I had this happen several times and can say it was a challenge to say the least. But I've wanted a true mono coil for several years and couldn't pass up the White's garage sale. I often wonder if either the OZ 7 1/2 or 12" would be more to my liking.
  4. Well my 8 x 14 coil came yesterday and I got to hunt at an old school yard where coal waste has been discarded for many decades. The coil seemed to run fairly good. Noticed a few things: Actual ground balance was a little higher (tad over 8) than with my other coils. Increasing the delay didn't change the GB as much as my other coils. It was obvious when the GB balance was off by the increased false audio reports. I could actually run gain to 7, but past that the machine would false in this bad ground. With the stock coil I usually settle with gain of 6. Very good coverage. Felt lighter than the 12" stock coil, but I believe the 12" is a deeper running coil, air test might be in order I could actually pinpoint better (off the front end of the coil) than the stock coils. My holes were noticeably smaller due to better target location. Plenty deep enough, I know some may laugh, but I dug beer beaver tails at 6" in this terrible ground. But I was hunting for gold not coins. Looking forward to my next chance after Nate passes by. No gold jewelry found this time.

  6. Video - Equinox 800 Depth Test

    Steve any idea when you might get your hands on this machine?
  7. Borrowed one from Gene Scullion back when he was a detector dealer and found one of the nicest gold rings ever with the Gold Bug Pro DP. Lightning fast recovery in the trash. Thanks again to Gene
  8. Scouting For A New Patch

    Very informative essay. Different ideas can really pay off. Thanks.
  9. Minelab Equinox Multi-IQ And Search Modes

    If the Equinox performs like people are thinking, it will take the market by storm. Don't know about their engineering department, but their marketing department appears to be the best.
  10. Minelab PI Coil On White's TDI

    That is an awesome description of coil/filter interaction.
  11. New White's Detector On The Way?

    For years I've wanted a good PI machine "TDI", but with a fair amount of true, actual, working discrimination without loosing depth. So many say it will never happen or rather they just don't know.
  12. Minelab Equinox Studio Photos

    I think that is a very realistic prediction, and that will give 1st Texas a chance to finish and test anything in the pipes.
