I read this on another forum and believe it or not it works! I placed an ad on craigs list saying I was looking for old properties to metal detect and I got a reply already, lady contacted me and they have a 1910 farm house 30 minutes from me, they said come dig and have fun!!!! if anyone wants to see my ad I would be happy to post it here. Give it a try many are doing it on the other forum and having great luck!
