Does anyone have any suggestions on what settings are best in real good soil that the moles have kept turned for a long time. I'm gonna hunt a house site that was built in 1796 and I have found a 1808 large cent here. I've only recovered one silver coin which was a 1917 merc. from this location but not with the V3. I'm needing tweaks or suggestions on any program to get to those really deep silvers because I know they are there. Any help would be appreciated. Thanks in advanced for your replies, Tadpole.
