600 W

The B45 is Airmar's smallest and most economical, dual-frequency, bronze, stem transducer. It features a single, 50/200 kHz ceramic element. The included fairing streamlines the transducer and increases the performance—even at higher speeds.

B45-DT-HB 600W Thru-Hull Transducer w/Fairing Block & Humminbird #9 Connector

The B45 is our smallest and most economical, dual-frequency, bronze, stem transducer. Its streamlined shape and High Performance fairing block deflects aerated water from the transducer's face for strong return echoes and clear display images.
