No one offered to buy my CZ-so I decided to start using it. What's the best way for jewelry? The doggone thing is pretty accurate most of the time and I'm digging a lot of tabs. Seems like I get the most non-tab items in the square tab region. I'm beginning to ignore the faint foil sounds. And geez, I forgot how hot this thing is on nickels. I want to get out of just coins and start finding rings, etc. Any help appreciated.
