Very nice mate, I tried my luck today and scored a heap of nails, some wire, some rusted metal and a lump of steel but I wouldn't have it any other way. The thrill of the hunt....
I don't think it's been hammered too hard or not with any efficiency considering the amount of old lead shot coming out of the ground through out. Maybe the pro's hear the difference between lead and gold signals and leave it behind? Have a few small 2 gram nuggets from jupiter creek and they came out between the lead.
