Positive ion control has been a feature just not in Cannon alone. Other electrics such as Scotty's, Big Jon, Walkers which I have 4 all have this as well. Protroll came out with a Black Box that allows the voltage to be adjusted to the downrigger cable in event of a hot boat. A hot boat is usually an indication of dirty or corroded ground connections on the motor, in the battery compartment, fuse block, or even a simple toggle switch, built up scale on zinc plates installed on motors is one of the biggest issues, they prevent electrolysis damage to those vital areas. Aluminum boats are more apt than fiberglass to become hot but can be prevented with periodic inspections & cleaning. Keeping connections & plates clean you shouldn't need a Black Box but not be ruled out. I do like the feature of the newer Cannon which has a setting that you can adjust the positive ions but the price is way out of range for new downriggers especially since I don't need them. I am a firm believer in the use of dielectric silicone grease for electrical connections.
