Got out last week to a couple of old sites I have been hunting. The first site is and old house and found an 1891 seated dime. It was about 7" deep. Was using the coin program and in open screen. Came in at 12-39-40, very dry rock hard soil. Manual Sensitivity was at 27, 50 conductive, ferrous-coin. Also at an old farm field found an 1837 bust half dime at 5", and was using a program I downloaded from here. It was one of Doc's programs and was using all metal in that one also. Both coins are in very good shape. The half dime come in at 12-38-39 and hit very hard. I am having fun with the CTX-3030, and keep learning something new every time i use it.
