It was a long weekend hunting, all i got was some silver rings (one Tiffany)and a nice folding knife. Went out side the box to some different spots today and bingo! The gold band sounded like a quarter,585 , no low at all, so i was pleasantly surprised to see it in my scoop. The small one is 18k and diamonds tested good and the silver gold buffed out really nice, a good looking ring.
Yes grave digger many of my largest rings have had no low at all, because of the copper or nickle and i find that most often when there is a low gold signal its a small ring. There is a differace in the over all sound if the ring is laying flat, a spongy sound. I would say 60% i can tell are a gold ring before i dig it.
