Garmin AIRMAR B175H 20° Tilt Transducer (010-11937-22)

Introduction

The Garmin AIRMAR B175H 20° Tilt Transducer is designed for anglers and boat owners who demand powerful high CHIRP sonar performance with a streamlined installation. Delivering up to 1 kW of sonar power, this premium thru-hull transducer features a flush-mounted bronze housing that protrudes less than 1/4 inch outside the hull, helping reduce drag while remaining safe for trailer rollers and bunks.

Its integrated 20° tilted ceramic element automatically compensates for hull deadrise, eliminating the need for a separate fairing block and simplifying installation. Designed for fibreglass and wooden hulls, the B175H operates within a high CHIRP frequency range of 130–210 kHz, delivering outstanding target separation, sharp fish arches, and accurate depth readings up to 1,000 feet. Whether you're fishing inshore, offshore, or over deep structures, this transducer provides dependable sonar performance with exceptional underwater detail.
