I have been playing with shooter's settings of Disc. 65 and notch in nickels. This is just dandy if you KNOW all that is in front of you is clad and tabs. Nickels are still on the board, just in case a nice chunk of gold would like to sneak in there.....right! However, today I went to a new park that did not seem to be eaten up with tabs and I was not getting the smaller objects as I thought I should, so, switched over to All Metal Motion.........things started hopping again. First this out of the box was a St. Christopher's medal. There it was, small but, glistening with that unmistakeble yellow color of gold, but, alas, 'twas not to be.......not today., After retreiving the piece it still looked like gold and was about the right weight for it's size, very small. But, I could find no markings and do not believe it is anything of value. But, I was hunting, so, it was a good day!!!
