My GTP1350

I have been using my GTP1350 for a couple of years now. It works great here in Iowa, Great coin machine, the price is right, I run my sensitivity a few notches higher when I am not in a trashy area. I found about 12 rings in two monthes on dry land, earing and junk jewelery as well. If your looking for rings, dig all penny signals. Listen to the weird tones and dig them.
