Bought a B.H. Tracker ID/505 at a garage sale for $10.00, couldn't pass it up. The handle's broken, other than that, I think it's in tip-top shape. I immediately took it to the back yard and started digging up junk, this I find very encouraging, I've been metal detecting over 30 years, by all rights there shouldn't be any metal in my yard, but that B.H. is going to town, a little practice and I hope to learn to discriminate out the junk. If any of you use a Tracker ID/505 please drop a line and tell me what you think and maybe give me some pointers.
