Minn Kota trolling motors offer a Universal Sonar feature, a new integrated, protected transducer puck and wiring that are compatible with most brands of fishfinders. The transducer and cables will be housed inside the lower unit of the trolling motor and, because they are compatible by agreement with popular manufacturers, the fishfinders retain their full warranties. The fishfinder brands that are slated for compatibility are Lowrance, Eagle, Humminbird, Zercom, GARMIN and Bottom Line. Minn Kota is initially offering the Universal Sonar feature on Genesis 55AP and 74AP models, Maxxum 50/SC, 65 and 74 models, as well as AutoPilot 55 and 65 models. The feature will sell for $69.95, and accessory adaptors will sell for $19.95 each. Minn Kota, Sturtevant, WI; (800) 299-2592; www.minnkotamotors.com.
