The transducer provides reliable depth data to your onboard displays through the NMEA 2000 network, helping you make informed navigation and fishing decisions in real time. The 235 kHz frequency offers balanced performance across a range of hull designs, and the in-hull installation minimizes external snag risks while maintaining clear signal. Designed for marine use, the unit draws modest power (9–16 V DC, about 200 mA) and uses 6 m of cable to fit a variety of boat layouts. With a LEN of 4 and CE compliance (IERC945), it integrates smoothly with compatible networks and standards.
