Owner lost in yard while playing with his dog. He and his wife had it narrowed down to roughly an eight foot circle. They spent several hours on their hands and knees looking through the grass. I wish they were all this successful and quick, after turning on my detector, a few steps and the first signal I had I reached down an pulled out his ring. It was right were they had been looking, and this was no small ring. Unbelievable how well hidden they are in the grass.
