Interesting test
« on: March 27, 2018, 02:07:15 pm »
Spent some time down in Quartszite last week. Have a tool Patrick designed that will plant a 'test nugget' at a known depth without disturbing ground too much. Planted a 1/2 gram piece of lead at 16". My 4500 (w/ Woodys mod) heard it quite well as did Bill S's 3500 (w/ Woodys mod). A stock 5000 could not hear it. A 7000 barely heard it scraping the ground. A friend in Prescott has a test patch and can hear a 1/3 gram at 24". Mods work! Good on you Woody!

  I’ve always seen improvements with the mods he’s done on my detectors.

What coil are you using for the test?

Thanks. I have just ordered a 17x13 evo for my modded GP3000. Should be good.

I have had a bit of time now with the 17x13 evo on my modified 3000. In all but the hottest deep red ground I can run the gain at least 50%. I always run on low frequency as it still manages to pick up the tiniest metal chips, unbelievable some times. Dropping the gain down gets rid of almost all noise. Not bad for a detector that "wouldn't " be able to handle a 17x13 evo! It picked up a quartz specimen at an old mine that yielded just under a gram.
