Hunted a lake this afternoon, one that's been just pounded to death, even with some PI detectors. A soft signal got me a penny about 14" deep, and it is unreadable on both sides, and thick as about 3 sheets of paper. I also found a chain with a .925 sandal attached. I severed the chain in half retrieving it. No problem......I just went back and quickly found the other half. The spent gun shells were found near by in the woods.
