Garmin AIRMAR B175L 20° Tilt Transducer (010-11938-22)

Introduction

The Garmin AIRMAR B175L 20° Tilt Transducer is engineered for anglers who require outstanding deep-water sonar performance combined with a clean, low-profile installation. Designed specifically for boats with higher hull deadrise, the integrated 20° tilted element automatically compensates for hull angle, ensuring accurate sonar beam alignment while eliminating the need for a traditional fairing block.

Its premium bronze thru-hull housing extends less than one-quarter inch below the hull, minimizing drag and allowing safe use with trailer rollers and bunks. Operating within the low-frequency 40–60 kHz CHIRP range, the transducer delivers excellent bottom penetration, dependable fish detection, and detailed underwater imaging at depths of up to 2,500 feet.

Built for fiberglass and wood hulls, the Garmin AIRMAR B175L 20° Tilt is an ideal choice for offshore anglers seeking reliable sonar performance, simplified installation, and long-lasting durability.
