I wish I could say I recovered these rings but both were recovered using my equipment by divers. First one was dropped of a boat dock while refueling at a marina in St. Pete. The High School ring was lost fishing in the mangroves of Fort Desoto Park in 12 ft of black water. They were both found with my trusty 8" Tesoro SS . I am always amazed when people detect for the first time and recover jewelry. HH, phil
