Collection: Transducers

Choosing the right transducer comes down to three decisions: how it mounts, what it reads, and whether it speaks your chartplotter's language. Thru-hull models from Airmar, Raymarine, Garmin, and Navico are the gold standard for clean water flow and accurate readings at speed, available in bronze for permanence or nylon and plastic for lighter builds. In-hull options like the Furuno M260 suit boats where drilling the hull is not an option, while transom mount transducers from Echonautics offer a straightforward installation for smaller or aluminum-hulled vessels. Power output ranges from 300W to 1kW, which matters for depth capability and target separation in deeper water. Frequency is equally important: dual-frequency 50/200 kHz units work well for general use, while CHIRP transducers in medium or high frequency deliver finer detail and better bottom discrimination.

Compatibility is the most important thing to confirm before ordering. Garmin transducers use an 8-pin connector keyed to Garmin fishfinders, while Airmar, Raymarine, and Navico units often connect via NMEA 2000, making them network-friendly on N2K-equipped boats. Multisensor models like the Airmar UDST820 and Navico DST-820 combine depth, speed, and temperature in one unit, reducing hull penetrations on a cruising or offshore boat.
