The Airmar B75C-0-H series is a 1 kW, high-frequency CHIRP-ready bronze thru-hull transducer designed for boats with flat or nearly flat hulls (deadrise 0° to 7°). It delivers precise sonar imaging across the 130 to 210 kHz frequency range with a constant 80 kHz bandwidth, providing excellent bottom detail and superior target separation for distinguishing small, tightly packed fish targets.
The transducer features a fixed 0° tilt element, ideal for flat hulls, with a narrow beamwidth of 15° to 9°. Its bronze construction ensures durability, and the nearly flush profile minimizes drag for efficient operation at higher speeds. The unit is compatible with Garmin multifunction displays via Mix-N-Match connectors and incorporates patented Xducer ID® technology for easy plug-and-play system integration. A fast-response water-temperature sensor is also included.
