Raymarine B275LH bronze through-hull transducer 1000W for CHIRP sonar wide beam

Bronze through-hull transducer B275LH, 1000W, 40-75kHz and 150-250kHz for CHIRP sounder module. Constant wide beam. Includes fairing block. Made of bronze, displays depth and temperature data.

The CHIRP B275LHW through-hull transducer is designed to deliver advanced bottom and fish detection performance in demanding marine applications. It combines two frequency ranges, low and high, providing excellent depth penetration capability along with high resolution in shallower waters.

One of its main differentiators is its constant wide beam at high frequency, which maintains uniform coverage of up to 25°, significantly improving fish detection in the water column. This feature is especially useful in sport fishing, where targets must be identified precisely without losing lateral coverage.

In the low band (42?65 kHz), the transducer offers great depth range, while in the high band (150?250 kHz) it provides greater definition and detail. Its 1 kW power allows it to work in demanding conditions while maintaining a stable and reliable signal.

Made of bronze for through-hull installation, it is designed to be fitted to fiberglass or wooden boats, ensuring durability and resistance in marine environments. It also incorporates a temperature sensor, expanding the information available to the user.
