The P74 is our lowest cost, dual- frequency, in-hull transducer featuring a 50/200 kHz single-ceramic element. This versatile model is also our best performing trolling motor and portable mount transducer. 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.
