Hunted for about an hour after work at the old homesite where I found the old brass reins guide. Set the surface elimination at maximum to get through some of the near surface trash that still left there. The old shotgun shell end caps all rang in the nickel range at size c and all were 7 to 8 inches deep. The iron horse ring also ranged around a nickel at 6 inches deep. The old wagon hub was found in all metal mode at 16 inches deep w/ the stock 9.5 inch coil. Thats gets me to wondering how something so big would be so deep when a coin would be 6 to 8 inches. When I used my old Garrett I dug many beer cans at 12 inches deep that sounded crisp as a coin at 4.
