I've only hunted twice with my Etrac.I get lots of 12-38 to 12-44 repeatable 2 way signals that end up as aluminum screwcaps.I'm hunting in the stock coins program with it in auto plus 3.I dug the deepest screwcap I've ever found today.It came in at 12-44 solid.It was 8 inches deep.Is there a way to avoid the screwcaps or just grin and dig them?The ground I'm hunting is rich organic soil but real dry.Thanks.Bill
