Garmin AIRMAR B175HW 12° Tilt Transducer (010-12181-21)

Introduction

The Garmin AIRMAR B175HW 12° Tilt Transducer is engineered for boat owners seeking powerful sonar performance without the complexity of a traditional fairing block installation. Delivering up to 1 kW of power, this premium thru-hull transducer features a flush-mounted bronze housing that protrudes less than 1/4 inch outside the hull, reducing drag while allowing safe placement on trailer rollers and bunks.

Its integrated 12° tilted ceramic element automatically compensates for hull deadrise, ensuring accurate sonar transmission without requiring a separate fairing block. Designed primarily for fibreglass and wooden hulls, the B175HW operates within a high wide-band frequency range of 150–250 kHz to provide outstanding target separation, detailed fish detection, and dependable depth readings up to 150 metres. Whether you're fishing coastal waters or exploring offshore locations, this transducer delivers reliable sonar performance for a wide range of marine applications.
