I spent most of the afternoon hunting an old park.I dug a bunch of clad and 3 wheaties.I stopped at an old spot by my house on the way home.It was dark and the bugs were getting bad.I hunted about 3 minutes got a 00-31 real sweet high shrill tone,it pinpointed deep.I carefully dug a 1941 Washington quarter in good shape.The quarter was about 8 inches deep.The site is trashy so I'm going back in the morning with the small coil on.I sure hope it rains as the ground is like concrete here.Bill
