Dig those pennies! Yah, I know, they are a waste of time, worth almost nothing . Why bother? Well, most silver and some gold rings read where the penny reads. There is no setting on ANY detector specifically for rings. You got to dig a lot of targets. If you want to cherry pick just the higher or lower conductive targets, go ahead. But you will leave the better finds for people who will go the extra mile and dig all penny signals. And I got paid over $50.00 (last year} to do just that in pennies, just so I could find lots of rings. And you know what? It really works.
