depth transducer / for boats / through-hull
The P74 is our best-performing, trolling-motor and portable-mount transducer featuring 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 face resulting in clear, bottom images—even at boat speeds above 20 knots. The trolling-motor mounting kit includes a 112 mm (4"), stainless-steel, band clamp and cable ties.
