Spent most of the day in the cold water using the AT Pro/9" x 12" concentric coil. It was calm, and there was nobody around but the ducks and geese. I had the whole lake to myself. After about 5 1/2 hours, I was getting chilled, and content with a gold ring, so I got out of my chest waders and warmed up in the car with the heater on full. I stopped at a place on the way home which has given up much silver in the past, and I scored another today. Below are the best!
