gm3
Hi guys I am new to the thread but have been detecting for a little while now, mostly for gold. Kevinslack I notice you are fairly new to detecting and are interested in prospecting. The whites gm3 machine was my first machine and though its 12+ years old it is still a kickin little machine. It will detect very small sized nuggets on the suface and depending on the ground I can get a bb size 2 to 3 inches down. Bigger items like a horse shoe from the comstock 2 feet down. with the sierra gold max loop it will bust out a silver dollar at 2 feet . You can get them for fairly cheap now $200 to $300 Ive been seing them for that recently. But be warned this machine comes with a bit of a learning curve as it has no disc functions just slight audio variation and a iron id meter But the sat speed is a Little help with the ground at sacrifice to depth. I am not sure how this compares to the sensitivity of newer machines but basically I think their main benefit is discrimination and ground handeling ability. I couldnt imagine trying to find things that tiny ,bird shot is troulblesome enough. I hear the minelabs do the same But am told will punch out a bb at 8 inches. Hope you find the machine you want!
