The Airmar B45-DT-HB is the smallest and most economical dual-frequency bronze stem transducer in the B45 lineup. Its streamlined profile pairs with an included High-Performance fairing block that channels aerated water away from the transducer face, delivering strong return echoes and clean display images. Wired with a Humminbird #9 connector, this unit measures both depth and water temperature and is sized for planing-hull powerboats and cruising sailboats up to 9 m (30').
