  1. Right on. I was going to guess it's in the 20 to 30 gram range, judging by the visual clue you mentioned. John B. you say; no wonder the stone is so clean...he must have performed the lick test on it. 😀
  2. Wow! I must say that's better than a shotgun, but not quite as good as the eagle scene in The Hobbit. 😂
  3. That's a beauty Chris; looks relatively fresh. Do you happen to know the mass of your friend's find?
  4. Howdy Sajuu, The GPZ 7000 settings I have already given you will handle the medium mineralized ground; for normal mineralized ground, just change the Ground Type from Difficult to Normal...that's all. The larger GPZ 19 coil will be noisy in 2 situations: electomagnetic interference from electrical power lines, or ground containing mineral salts such as alkali. If you change the Gold Mode from High Yield to Extra Deep it will help quiet salt-rich ground. If the noise is from nearby power lines, use the automatic Noise Cancel feature. Good luck to you!
  5. That's great Fred; ZVT will find the deeply buried meteorites with ease.
  6. Hi Sajuu, You're welcome. GMk is just how I refer to the new Minelab Gold Monster 1000: http://www.minelab.com/customer-care/product-notices?article=305146 It uses VLF technology and will not go nearly as deep as a pulse induction machine in mineralized ground. The GMk will not be available until April according to Minelab. Quote Edit
  7. Greetings Sajuu, I know that the GPZ 7000 can detect coins the size of a U.S. quarter dollar or larger at 2 feet with the stock GPZ 14 coil, but I doubt that even the GPZ 19 coil would hit a large object like a bronze pot at 13 feet in mineralized ground...maybe at 7 feet. You may be better off using ground penetrating radar for such large and deeply buried items. I've also seen large, deeply buried iron meteorites recovered by using pulse induction detectors with homemade coils several feet in diameter.
  8. Hello Sajuu, In highly mineralized ground, try these settings; Gold Mode: High YieldGround Type: DifficultSensitivity: 15Ground Balance Mode: AutoVolume: 15Threshold Level: 35Threshold Pitch: 25Audio Smoothing: HighVolume Limit: 3 You may also have to reduce the sensitivity if the ground is severe. Good luck to you!
  9. Howdy Fred, The 161g Franconia is a stony meteorite, and the 166g iron is from the Quartzsite area; both have not been classified.
  10. Hey Dave, I haven't actually had the GPZ 7000 at Stewart Lake; I used my GPX 5000 there back in 2012 and didn't have any luck, so I started hunting with my eyes and a magnet cane - that's how I found the fragments.
  11. And vertical cut banks along streams, rivers and desert dry washes.
  12. Theoretically one could use a piece of pvc pipe just long enough to accommodate the 5" round coil and the control/handle assembly, and voila - an ultra portable pinpointer with iron discrimination.
