I was called by a client in Wells Beach Maine, who had lost his wedding band in the surf, while tossing a ball. A couple of days had passed, and we had been hit by several rain storms during that time. The client stated he was about waist deep in water and had thrown a ball, and felt the ring fly off. He had the presence to make visual landmarks and was able to offer enough info to place a grid at low tide when there was no water. After about an hour, recovered the ring in about 3″ of beach sand within the grid.
