Fished planer boards for the first time yesterday on Tellico. I also had a couple of long lines out and only caught fish on the long lines. Makes me think I was doing something wrong with the boards. I didn't really know how much line to put behind the boards. For the most part, I had 15' to 20' behind them with 1/16 oz jigs. Was this too much? How do you know how much to put behind them to achieve a certain depth?
