Garmin Bronze Thru-hull Wide Beam Transducer w/Depth & Temp - 20° tilt, 8-pin - Airmar B175HW

The Garmin Bronze Thru-hull Wide Beam Transducer with Depth & Temperature sensor delivers 1 kW sonar performance without requiring a fairing block. This Airmar B175HW transducer uses a tilted internal element to automatically accommodate virtually any hull deadrise, eliminating the need for costly fairing modifications. The bronze housing protrudes less than 1/4-inch below the hull, allowing the transducer to rest safely on trailer rollers and bunks without damage—a critical advantage for anglers who frequently haul their boats.

Built with Garmin's proven marine sonar architecture, this 8-pin transducer integrates depth and temperature data into a single sensor package. The wide beam pattern covers more bottom area per sweep, providing superior target detection and bottom mapping across speed ranges. The 20-degree tilt accommodates both deep-V offshore hulls and shallow-deadrise bay boats without angle adjustment, making it an ideal retrofit solution for mixed-use fishing platforms. Real-time temperature readings help identify thermoclines and seasonal fish holding zones, while simultaneous depth tracking locks you onto structure and changes in bathymetry with confidence.

This transducer suits both weekend anglers upgrading older equipment and serious offshore fishermen standardizing their sonar across multiple hulls. Installation requires thru-hull mounting with proper sealant and backing plate, but the compact bronze design minimizes hull penetration complexity. The 8-pin connector integrates with Garmin's current marine chartplotter lineup, and the transducer pairs with Garmin's low, medium, high, and high wide beam frequency options, giving operators flexibility to match their sonar to specific fishing depths and target species.
