Garmin B175L Bronze 20° Thru-Hull Transducer - 1kW, 8-Pin

The Garmin B175L Bronze 20° Thru-Hull Transducer is purpose-built for serious anglers and boaters who demand reliable sonar performance across variable hull designs. This 1kW thru-hull transducer delivers the precise bathymetric data and fish-finding capability needed for consistent success on the water, whether you're navigating shallow coastal bays or deep offshore structure. The bronze housing design with minimal hull protrusion makes it the ideal choice for trailerable vessels where durability and clearance matter.

The B175L features a tilted 20° element that accommodates virtually any hull deadrise without requiring a fairing block—a significant advantage when retrofitting existing installations or building new systems. The bronze construction resists corrosion in saltwater environments while the flush-mount design protrudes less than 1/4 inch outside the hull, allowing the transducer to sit safely on trailer rollers and bunks without damage during launch and retrieval. The 8-pin connector integrates seamlessly with Garmin's NMEA 0183 and proprietary sounder networks, delivering full power output at 1kW for maximum sonar clarity and target definition in both freshwater and saltwater applications.

This transducer excels aboard center consoles, cuddy cabins, and fishing boats where hull space is premium and performance cannot be compromised. Installation is straightforward for experienced technicians familiar with through-hull penetrations, and the compact footprint minimizes stress on the hull structure. Whether paired with legacy Garmin equipment or newer chartplotters, the B175L delivers the reliable, low-frequency sonar performance that separates productive days on the water from frustrating blanks. For boaters seeking a proven, durable thru-hull solution that performs in any deadrise configuration, this Garmin offering represents a time-tested choice backed by decades of marine electronics expertise.
