Come to find out my camera has no audio. So much for that. I banged the coil off everything I could hit with it and no falsing.
One thing bothered me though. that was when I had a sweet silver signal and I could not get the cursor off the top left corner of the screen. I played with that signal for quite a while before I gave up and dug it. It was a 1939 quarter about 4-5 inches deep and no other signal after I removed it. Makes me wonder how many coins are missed because of that. I was convinced it was a coin from the tone. And it was. So if you get a sweet signal in the left corner I'd check it.
