Inside Hull Angled Puck Transducer mount to the inside of most fiberglass boat hulls and transmit the sonar signal through the hull. On hulls with a deadrise less than 15 degrees, a flat bottom Puck Transducer should be used. For angles greater than 15 degrees, an Angled Puck Transducer is recommended to assure the sonar signal travels downward. Angled Puck Transducer shown is XAP-6-16.
