Garmin AIRMAR B175L 0° Tilt Transducer (010-11938-20)

Introduction

The Garmin AIRMAR B175L 0° Tilt Transducer offers professional-grade CHIRP sonar performance in a streamlined, flush-mounted design. Built for anglers and boaters who want the benefits of a powerful 1 kW transducer without the added drag and complexity of a fairing block, the B175L combines advanced sonar technology with a durable bronze housing that protrudes less than one-quarter inch beyond the hull.

Its internally tilted element compensates for hull deadrise, allowing the transducer to maintain optimal sonar performance while eliminating the need for external fairing blocks. Operating within the low-frequency 40–60 kHz range, the B175L provides excellent deep-water penetration, dependable bottom tracking, and reliable fish detection at depths of up to 2,500 feet.

Designed for fiberglass and wood hulls, this transducer is an ideal solution for anglers seeking powerful sonar performance with a clean, low-profile installation.
