After practicing with my BHQDII for a month I finally found something of value. I've been practicing pinpointing with it and getting better and today I found a wedding ring I lost 10 years ago while planting trees at the back of my yard. I pinpointed the area and my wife dug a semi-circle, flipped the flap over, and there approx. 8" down was my ring. This was the first find of anything other than junk iron and pull tabs.
