Hello folks, I'm learning the At pro and have recently started detecting streams. How do you start? I ground balance, then do I manualy notch down the ground balance? I've gotten fairly good with it on land, I just put third set of batteries in it. I'm improving on my pinpointing. I have a White's M6 and know it well. I went saturday and found several pennies, bottle caps,tabs, sinkers, depth of stream 6 inchs to about 3 feet, can't bring myself to submerge it. Thanks Don Johnson
