The Cannon Magnum 5 ST electric downrigger features the fastest retrieval rate on the market (250 feet per minute) and a Short-Stop feature that protects the boat from swinging weight. Includes 24″ heavy-duty stainless steel boom, and fixed mounting base. Magnum is built tougher and smarter to make you a better angler. Cannon Edge Design features fewer moving parts, one-piece composite construction, a redesigned boom end, protected circuit boards, and easy access to the spool, switches, plugs and mounting knobs.
