Garmin B175M Bronze 20° Thru-Hull Transducer - 1kW, 8-Pin

The Garmin B175M Bronze 20° Thru-Hull Transducer – 1kW, 8-Pin is a professional-grade sonar sending unit designed for serious anglers and boaters who require reliable bottom and fish detection in both freshwater and light saltwater environments. This transducer is engineered to enhance your fishing experience by providing consistent and accurate sonar data, which is crucial for locating structures, thermoclines, and gamefish.

Operating at a power output of 1 kilowatt, the B175M features a 20-degree cone angle and a medium-width beam pattern, making it ideal for moderate-depth fishing and navigation. Its bronze housing is designed to resist corrosion from saltwater exposure and UV degradation, ensuring durability over time. The 8-pin connector allows for seamless digital communication with compatible Garmin chartplotters and sonar units, enabling advanced signal processing and real-time frequency switching.

This transducer is particularly beneficial for captains operating in depths between 2 to 1,500 feet, providing superior signal clarity compared to transom-mounted alternatives. Its thru-hull installation requires only a single hull penetration, which minimizes aeration turbulence and delivers clean sonar returns even at high boat speeds. The B175M integrates effortlessly into existing Garmin sonar systems, making it a valuable upgrade for any fishing vessel.
