I was out two days ago walking my older dog "Lee". We stopped to take a break on a grassy median between a store and a highway. While stroking my dog"s back the ring came off,I think.We stop here every day. I had my Omega out twice in this area .Cannot find it to save my life. Median is about ten feet by twenty,mostly medium height grass. There are also overhead high-tenson wires as you near the road causing some emf chatter on the Omega. Months ago I air-tested this ring and the reading was 51. The ring is 14kt with a cheaper metal ring keeper on it.My question is, after trying numerous settings on this detector ,can I tune it to find this range only? There is ground chatter from the other stuff that has worked it's way into this area over the years. Any I/P would be greatly appreciately. I have also looked for this on my hands and knees with my Garrett pinpointer to no avail. Thanks Kevin R
