I used the AT Pro in the water for about 2 1/2 hours today. I did get a ring, a working watch and some coins, but then I got no hits, not even junk hits for about an hour. At this point, I swapped machines and brought out the Infinium PI, which always breaths new life into a hunted out spot. It too got a ring, a chain but no coins. All in all, it turned out to be a good day, except for that brutal strong north wind, which caused several waves to run into my chest waders.
