I received some California LiDAR data from Matt. It is very easy to install and view in Google Earth. It is very interesting. I think I found a few rows of stacked rocks in a few deep gullies and/or along some stream beds. I will check them out this spring or summer. Caterpillar logging trails and caterpillar built fire breaks appear in many places. Mostly on hillsides and ridges. Have a good day, Chet

My first GPZ, about 3 years ago had a similar problem. In High Yield, Normal it would run great most of the day. In the afternoon when the battery was around 50% down it would sound off like you describe “detecting over a bed of tiny birdshot”. I could charge it at the car for 10 minutes and it would settle down until the battery was again down around 50%. I think an internal voltage regulator must have been failing. The replacement detector cured that problem. My standard settings are High Yield, Normal and 20 Sensitivity. Most of the time wet grass, mud and water have no effect. But in some areas at times I still experience the same severe effects in wet grass. Chet

That same bogus GPZ 7000 ad is back on eBay again!! https://www.ebay.com/itm/Minelab-GPZ-7000-All-Terrain-Gold-Metal-Detector/292977609828?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3Db7912ae7cf7f4f40bcf92f59bd96da82%26pid%3D100675%26rk%3D1%26rkt%3D15%26sd%3D292977609828%26itm%3D292977609828&_trksid=p2481888.c100675.m4236&_trkparms=pageci%3A554825e1-37c4-11e9-8000-74dbd1805566|parentrq%3A1cbad2951690ad793fa57401fff2a2c3|iid%3A1

I have experienced the same severe effects in wet grass with both the GPZ 7000 and the GPX 5000. I just move on to the clear patches and skip the wet grass areas. The problem mostly goes away as the grass and ground dry up. It still detects the roots of Joshua trees and Barrow cactus. In between wet and dry seasons it sounds off as I swing back and forth between grass and bare areas. In this situation I allow the detector to automatically ground balance as I hunt as much as I can of each area in sequence. Have a good day, Chet

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

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

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

Hi Dave Will they have some on the market soon? Thank you, Chet

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

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

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

Hi Steve Great write up; a lot of great information. Thank you, Chet

Hi Peg Wow! Great Job! Have another great day, Chet

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
