2 Indian heads in local parks using the 5.75" Round Concentric coil with the Tejon. I was really surprised and impressed. . I have had thee coil for a couple of months, but really started hunting with it this month. I am not sure what parks, but it was in some areas with heavy trash. I was cleaning the pennies for the month, because hunting is fast coming to an end in the Wisconsin area and the Indian heads were there. 1895 and1871 and not in too bad a shape.
