    Nugget Mesh Size

    Hi Green Those are some nice chunky nuggets. They haven’t been beat up, flattened and worn smooth by traveling for millions of years in an ancient river. Their size and shape are very detectable by most pulse induction detectors. They are typical of nuggets that are found closer to the original source of the gold. The three you show with your chart are typical of what is found in Californian hydraulic pits which are ancient river gravels. Have a good day, Chet

    25 Inch Coil Zed 7000

    Hi Dave Thank you for clearing up my confusion on the cables. The reduction in weight and having a selection of different coils for different hunting situations will be a big gain if these coils are stable and get on the market. Have a good day, Chet

    25 Inch Coil Zed 7000

    Hi Dave In your previous videos the coil cords where inside the shaft. In the new videos the cord appears to be spliced and outside the shaft. Can you describe the connections; especially on the stock GPZ14 coil? Do you think the temporary connections have any effect on performance? I like the test results with the 22” x 21” coil. Here in the US I run the GPZ19 in High Yield, Normal much of the time. It would be great to see the lighter weight 22” x 21” coil performance compared with the GPZ19 if you can fit that into some future testing? I do understand that High Yield, Normal timings may be noisy in your ground. Have a good day, Chet

    Franconia Hunt

    Hi Lunk I made it to the south side of Franconia in March. I had never hunted for meteorites before so I dug everything. Using the GPZ 7000 resulted in a lot of deep and shallow junk. Evidently it was a WW II training area resulting in a lot of 50 Caliber bullets. There are a lot of small pieces of screen wire everywhere. The wire is on or near the surface so the magnet in the handle of my pick came in handy to quickly pick it up. I didn’t find any meteorites but I will try again in the future. Have a good day, Chet

    Hi Dave Is this from the same manufacturer? Have a good day, Chet https://www.youtube.com/watch?v=JfiJy3o95SE

    Dumb Question

    Hi Sometimes after having the GPZ on for long periods while manually transferring Find Points and Way Points to my computer the GPZ is very noisy the next time out. When this occurs an extra-long balancing over the ferrite core cures it. Have a good day, Chet
  8. Brian; thank you for starting this. Steve; I look forward to trying your procedures. Clay; thank you for the offer to help in this effort. Have a great day, Chet
  9. Hi Steve Great write up; a lot of great information. Thank you, Chet

    Bench Monster

    Hi Peg Wow! Great Job! Have another great day, Chet
  11. Hi Jennifer Apparently the open spoke design of the 19” coil allows the receive coils and the transmit coils to vibrate separately when bumped. I glued a flat, cut to fit, PVC cover to the bottom of the factory skid cover. This reduced the falsing considerably. Perhaps the Nugget Finder skid plate will also reduce the falsing? Also use of the GA-10 Guide Arm helps to control the 19” coil and prevents bumping into so many rocks and stubble. Otherwise maybe you can compare your coil side by side with someone else using the same settings to determine whether to send it back for a replacement. My 14” coil is solid and quiet. But I have a friend that has falsing on both size coils. Have a good day, Chet
  12. GMT Pin-Pointer I modified my GMT to fold down and hang on my pack belt. It works quite well with my GPZ 7000 with the monster 19” coil. If you lay the two detectors close together and manually tune the 7000 you will find a few relatively quiet EMI null frequencies. I normally run at frequency 22. When in use I lay the 19” coil behind me or far to side of the dig site to further minimize the interference. The GMT works well in the compacted length. It will still telescope out to full length for extended hunting in nail patches. Have a good day, Chet
  13. Hi G.B. Thank you for doing these very informative mode comparison tests. The wireless microphone audio was a little weak and hard to follow at times; for clarity I have summarized my understanding of your tests as follows: Each test run was on the following targets in sequence that have been buried for more than six years: 1. a 22 bullet at 6” 2. a 22 bullet at 8” 3. a 22 bullet at 9” 4. a 22 bullet at 12” 5. a ½ oz piece of lead at 12” Do you know the shape and size? 6. a ½ oz piece of lead at 14” 7. a ½ oz piece of lead at 18” 8. a 10 oz piece of lead at 27” Do you know the shape and size? JP’s usual conservative settings were used which are..... • Threshold: 27 • Audio Smoothing: OFF • Volume: 8 (I use the B&Z booster through twin speakers) • Volume Limit: 8 to 10 • Ground Balance: Tracking • Gold Type Mode: General for solid heavy nuggets over 10 grams, High Yield for rough gold or solid nuggets 15 grams and down • Ground Type Mode: Difficult, because the ground here is nasty • Threshold Pitch: 60 • Ferrite Balance: Perfect at all times (regularly check it) First test run starts at 2+ minutes into the video; High Yield Gold Mode, Difficult Ground Mode Second test run starts at 6 minutes into the video; General Gold Mode, Difficult Ground Mode Third test run starts at 8 minutes 45 seconds; Deep Gold Mode, Difficult Ground Mode Fourth test run starts at 12 minutes; High Yield Gold Mode, Normal Ground Mode Fifth test run starts at 15 minutes 35 seconds; General Gold Mode, Normal Ground Mode Sixth test run starts at 18 minutes; Deep Gold Mode, Normal Ground Mode Do you have any information on shape of the large lead pieces? I look forward to your video of the GPZ 14 coil responses. Have a good day, Chet
  14. Referencing high/low sounds associated with gold, this video is very interesting. Try to guess which sounds are from gold before the answers are given at the end of the video. Have a good day, Chet

    JP On Using The New PRO-SONIC From Minelab

    Steve, the WM 12 continues to work when the headphone jack is used. That is how I connected the oscilloscope up to both paths simultaneously to measure the 20 millisecond delay in another post on Bluetooth delay. Have a good day, Chet
