Interesting test
shepcal@sti.net:
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!
WesHawkins:
I’ve always seen improvements with the mods he’s done on my detectors.
Rockwall:
What coil are you using for the test?
shepcal@sti.net:
I was using a 12"EVO
Rockwall:
Thanks. I have just ordered a 17x13 evo for my modded GP3000. Should be good.
