I Decided to stop by a local park on my way home that has been heavily hunted over the last few decades, and detect for a while with my new E-trac on Tuesday I was able to find a 1952 dime then in the same hole I got another silver signal and got a 1936 mercury dime then it was getting dark so I went back after work on Wednesday and found a 1945 and a 1927 mercury dime, the 1027 had a nail laying across the top of the dime I was very impressed that the E-trac was able to see thru the nail and pick up on the mercury dime.
