Airmar B45

The B45 is Airmar's smallest and most economical, dual-frequency, bronze, thru-hull, stem transducer. Its streamlined shape deflects aerated water from the transducer's face for strong return echoes and clear display images. Airmar's High-performance fairings are recommended for all installations to obtain the best possible results.
