So, I lower my downrigger until the counter says 50 feet. The ball is behind the boat and the transducer can't pick it up. How deep am I? That's a question I always ask myself when using the downrigger.
So how do you use yours? Set it at "50' " (for example), and then if you get a hit you later re-set it to "50", not knowing or caring how many feet deep you really were? Only caring that you got a hit at the "50" on the counter and so that's how you know how much line to let out again?
