Went out for a while today. Had the EX II dialed in to a program that sensitivity was maxxed out. Got tired of digging small fragments of copper so I backed the sensitivty back to 26 and 5 minutes later I dug a 1964 Rosevelt. I just wonder if I had not backed the sen down when I did would I have this coin today. Its possible i would have passed it by, Over all today was a good day swinging the coil. Accually broke a sweat.
