I found this 18K gold mans ring yesterday. It was right in the middle of several metal support posts, and underneath one of the slides. I was using my Tesoro Bandido II Umax, with the 7" precision concentric coil that I took off of a Tesoro Mojave. I had the sensitivity turned down to 5 in order to get closer to the metal posts. I am going to put an ad in the local paper's lost and found section, to see if anyone claims it.
