Humminbird XP 9 20 T Transducer. Your boat's hull must be of single-layer fiberglass construction and be free of trapped air or voids in order for a puck transducer to operate correctly so cored fiberglass metal and wood will not work. This unit is meant to be glued to your inner hull with a slow-cure epoxy which is included and connects to your compatible Humminbird sonar or fish finder system via the included 15-foot cable.
