Out water detecting
Detected an old swimming hole Saturday morning up to about 3 or 4 feet (whenever the beep speaker goes under I can't hear it until I buy some H2O headphones). Bottom was pretty stony and bedrock just downstream. Found a bunch of regular clad, a wheat penny, and an old penny so toasted and worn not sure if I'll ever be able to figure out what it was. Will post pics if I get a chance.
