As I continue to spend my very brief metal detecting adventures in my near by heavily hunted old park I have started noticing that I am pulling good finds from holes that contain more than one target. Typically it will be deeper iron(nails, wire bits) located below the coin. lately I have been getting coins in the same hole as pull tabs that are at, or above the coin level. I don't understand how this is possible, but I dig based on 3 frequency pinpoint response after getting a desirable motion mode reproducible VDI. I can't make this happen in air testing, but it sure happens in the field. A little mineralization strength makes the difference I guess. Anyone having similar experiences?
