Description

This Raymarine transducer pack pairs two single-element bronze thru-hull CHIRP transducers, the B75L and B75M, with the Y-cable needed to run them together from a single Raymarine CHIRP sonar module. Airmar Tilted Element technology sets each ceramic element at a 12 deg offset, giving built-in deadrise compensation for hulls in the 8 - 15 deg range so no fairing block is required. The B75L covers 40-75 kHz with a 32 deg / 21 deg beam width, while the B75M covers 80-130 kHz with a 24 deg / 16 deg beam width, together delivering wide CHIRP bandwidth for excellent bottom tracking and fish-target separation across shallow and deep water. Both transducers are low-profile bronze units for fibreglass or wood hulls, each fitted with a 9.1 m (30 ft) cable, and the supplied Y-cable connects the pair to a CP450C, CP470 or CP570 CHIRP sonar module.

Which sonar modules do these transducers work with?
The supplied Y-cable connects the B75L and B75M pair to a Raymarine CP450C, CP470 or CP570 CHIRP sonar module. The pair is designed to run as a dual-channel CHIRP installation on those modules.
Do I need a fairing block?
No. The 12 deg Tilted Element offset provides built-in deadrise compensation for hulls in the 8 - 15 deg range, so the elements point straight down without a fairing block.
What hull types are these suitable for?
The bronze housings are designed for fibreglass and wood hulls. They are not recommended for direct fitting in metal hulls.
