Sandman is 100% correct. HE is the reason I have one, and after a couple of months I feel that it still was the right machine for me. It is WAY sensitive, and on one occasion I was testing it against my 1350 it picked up a .22 shell casing 11" (measured) in a wet sandy river bottom, the 1350 wouldn't get a hit no matter what I tried. Get it you will like it, BUT you will have to learn the tones and what it is trying to tell you. I am still learning.
