I spent a couple hours detecting a very small area at the local "pull tab park" with my Etrac and the small butterfly coil. Nice thing about rain is that it makes the digging easier, the grass don't turn brown and those deep signals come through much more distinctly. Other than a half dozen broken pull tabs, a couple aluminum screw caps and a few old bent nails, it was a decent hunt for this particular park. Quarter was every bit of 9 inches. IH cents were 5 - 7 inches. Nothing to brag about. But I've' spent far longer and dug far less. HH Randy
