So I got a old pioneer 101 and I'm looking for a specific iteam in my yard I'm trying to find I've found nuts bolts pull tabs old cans and and a couple Coins with current settings but about two years ago my brother lost a silver ring and I'd like some opinions on a good setup so I don't find so much junk thanks for all your help. If it helps it was snowing at the time so if its still in the yard I don't think it could be too deep
