Utah.....I started this thread to see if I was doing something wrong detecting with the etrac. But with all the replies I think it is just the nature of the BEAST...lol..I dug a reading today with CO 44 about 2" deep. I started digging away knowing it was a memorial. I had been digging others at that depth so I wasn't really careful about my digging style. Guess what popped up!!! yep a mercury dime and I scratched the face of the coin..... @#$ though I had a memorial for sure...With the Trac you just never know.....Also dug a Roosie and Washington. Good day.....Thanks for all the replies guys....appreciate the info...
