B175 Through-Hull Transducer

B175 Overview

B175 low-profile, CHIRP-ready transducers designed for high-speed applications such as center consoles. The B165 can be used individually or in pairs with Raymarine CHIRP sonars.

The B175L transducer has up to 20 kHz of total bandwidth and transmits across 40 to 60 kHz bands. The CHIRP low-frequency band is a deep-water performer delivering excellent coverage and tracking. 

The B175M CHIRP medium frequency version operates at a frequency range of 85 to 135 kHz. The B175M  reveals fish at medium depths of up to 457 m (1,500') and delivers ultra-clear target resolution.

The B175H transducer, a high-frequency CHIRP transducer, delivers a narrow beamwidth—excellent for pinpointing fish tight to wrecks and reefs.  High frequency provides excellent baitfish and schooling gamefish target separation. The B175H has up to 80 kHz of total bandwidth for superior shallow-water performance and bottom detail.

The B175H is a high-frequency, wide-beam transducer operating across a frequency range of 150 to 250 kHz with a fixed 25° beam. The wide beam provides twice the coverage and excellent fish arches compared to narrow-beam transducer options. The B175HW CHIRP transducers are ideal for coastal and offshore fishing, offering excellent resolution and maximum coverage down to 152 m (500').

All B175 series transducers used a tilted element. The ceramic element is fixed at a 20°, 12°, or 0° angle within the housing. The tilted element corrects for the hull deadrise and orients the sonar beam to ensure maximum echo returns.   

When used individually, the B175 transducer must be installed using a single transducer operation cable, part number A80328   

When installed in pairs, join the B175 transducers using a transducer Y-cable, part number A012146.
