Product Overview

Airmar B75C 12 Tilt Low CHIRP Transducer

This Airmar B75C transducer is designed for deep-water performance with a low-profile, thru-hull housing. It features a depth and fast-response water-temperature sensor that operates on low frequency CHIRP signals from 40 kHz to 75 kHz. The device is ideal for stepped, planing, or displacement hull boats.

With a maximum power rating of 300 W and a maximum depth capability of 366 m (1200'), it provides excellent coverage and tracking while maintaining a good display resolution at high speeds. The B75C transducer includes a tilt element that corrects for the hull's deadrise, ensuring accurate depth readings.

Whether you're navigating through deep waters or operating at high speeds, the B75C is equipped to deliver clear and detailed imaging, making it a valuable addition to any boat.

Expert Overview

The Airmar B75C Tilt Low CHIRP Transducer is a thru-hull marine sensor designed for accurate depth and water temperature readings in deep-water environments. Operating within a low-frequency CHIRP range of 40 kHz to 75 kHz, this transducer is suitable for integration with compatible marine electronics requiring detailed imaging. It features a 12� tilt element to compensate for hull deadrise, ensuring consistent performance across various vessel types, including stepped, planing, or displacement hulls. With a maximum power rating of 300 W and a depth capability of 366 m (1200'), the B75C-12-L-HB model provides signal processing for maintaining display resolution, even at higher vessel speeds. Its bronze housing is intended for installation on fiberglass or wood hulls, offering a flush profile to minimize drag. This unit is for IT buyers specifying marine hardware for commercial or recreational vessels requiring reliable underwater data acquisition.
