The P74 is our best-performing, trolling-motor and portable-mount transducer. It features a dual-frequency, 50/200 kHz, single, ceramic element. This versatile model is also our most-basic in-hull unit. In-hull mounting eliminates turbulence under the transducer’s acoustic face, resulting in clear bottom images—even at boat speeds above 20 knots (23 MPH). The Trolling Motor Mounting Kit includes a 112 mm (4"), stainless-steel, band clamp and cable ties.
