I had them on my boat when I bought it. Good riggers. Direct drive so no belts to worry about. You have to use stainless steel line - no braid. The positive ion control shoots a current down the line and controls the auto stop feature, such that when the line breaks the water, the motor stops. You can't automatically stop the thing before the line breaks the water, so stacking rods is tough unless you're prepared to watch the line coming up closely and shut the rigger off when the top line clip comes out of the water. If you're not planning on stacking rods - the Canon's are a good option. I sometimes fish with three guys on the boat and want to stack at least on one side. Sold my Cannons and bought Scotty.
