I almost didn't dig the target, because it was so weak and bouncy. It was surrounded with all kinds of junk, but I kept seeing a 81 flicker in all that garbage. I thought it might be a copper. I dug down a little over 6 inches and out pops my first mercury dime. The Gold Bug Pro sure can separate out the garbage from the good stuff.
