I have two of the uni-troll cannon down riggers and love them, just have to figure out how to gently let the line down and get the drag set just right to pull out as the ball goes down but have used them off and on for a long time and have not had any problems with them, a buddy has the electric cannon ones and they work nice but hate how trying to adjust to a different level is so hard to do fine adjustments with the electric reel up, but he likes them I just wont spend the money for the little I use the down riggers I have.
