AIRMAR B275LHW is developed specifically for coastal fishing, where high resolution and wide coverage are essential. This CHIRP transducer operates in the 150–250 kHz high-frequency range and delivers a constant 25° beamwidth, which provides a significantly larger coverage area under the boat compared to traditional high-frequency transducers.
With a total power of 1 kW and support for both low (42–65 kHz) and high (150–250 kHz) CHIRP, the B275LHW is suitable for both detailed structure and fish searching in coastal waters as well as deeper water, with a maximum depth of up to 3,000 ft (approx. 914 m). The transducer is designed for boats of 7.6 meters and above and is suitable for fiberglass and wooden hulls.
The robust thru-hull construction is optimized for hulls with 19–25° deadrise, which ensures the correct beam angle and reliable sonar images while underway. The transducer measures depth and temperature and comes with a fixed cable for professional installation.
