That's a lot of beaver tails and bottle caps, assuming you were using coins mode? I was digging a lot of that up with mine, then I started using jewelry mode, and my finds started looking better. Also, with mine, if I got a high tone one way and nothing else the other way, I put it in zero to sort of get an idea where it is. Sometimes it turned out to be a deep beaver tail, but other times, it was silver, or a nice relic.
