I was swinging and pinging for just over an hour last night. I only dug 6 hits. I was specifically hunting jewelry. Other than a door hinge and the oblong piece each hit was a winner. Thanks for the jewelry hunting class Gerry. Less digging better finds. I don't think the heart is silver. No marks
I have tried Gerry's settings for the X too. So far just a couple of junk rings but it does cut down on the noise in junky parks so I have been using it quite a bit.
