I found this with the Deus and 9" X35 coil on a sports field. It was very deep and I was just getting a little peep of a signal, but it was consistent. It was coated with a lot of caked on crud, and I thought it was just a piece of junk jewelry. When I got home I started to throw it in the garbage, but then decided to clean it up a little. I'm glad that I did because it is sterling silver. That is why you should always check something out, even if you think it is just junk.
