I was out detecting today in my neighborhood and a couple asked me if I could look for the husband's gold wedding ring that he lost two weeks ago in their front yard. So I'm going over there tomorrow to see if I can find it, and I will scan the wife's similar ring to get an idea of ID number. Does anyone with experience finding gold rings have any advice? I have a Minelab Vanquish 440. I'm considering turning down the sensitivity, since the ring will be shallow or on the surface, and discriminating out high tones and iron. The front yard at the house is not huge--only about 0.15 acres--and they think the ring could really be anywhere in the yard. Just trying to maximize my chances for success; thanks for any help!
