This isn’t a good video, but I wanted to show how I can tell a bottle cap,from a quarter. I’ve got the Deus running in a custom program,that eliminates the pull tabs,zink pennys,and nails (iron) since I mostly hunt coins. I use the “wiggle back” method to pin point my targets. This does two things at once! It pinpoints the target,and if it breaks up,it tells me it’s trash,and I just move to the next target!
