I was dry sand beach hunting today with my Dual Field (digging everything) and found a couple of rings. One is marked 10k and is white gold. The other has no hallmark and is a big heavy men's wedding band. It is not magnetic and when I got home I ran it in front of my Etrac and it hits a consistent 12-29. I am still a n00b at the Etrac, but maybe you Etrac experts could tell me if those numbers mean anything to help me ID the metal of the mystery ring....
