Garmin B175M Bronze 0° Thru-Hull Transducer - 1kW, 8-Pin

The Garmin B175M Bronze 0° Thru-Hull Transducer is purpose-built for anglers and boaters who demand reliable, accurate sonar in a compact, hull-friendly package. This 1kW transducer pairs with Garmin fishfinder systems to deliver real-time bottom imaging and fish detection with minimal hull penetration—critical for vessels ranging from center consoles to aluminum jon boats. Whether you're chasing walleye in freshwater or working structure in coastal waters, the B175M's bronze construction and innovative design eliminate common installation headaches that plague traditional transducers.

The transducer's flush-mounted bronze housing protrudes less than a quarter inch outside the hull, allowing it to sit safely on trailer rollers and bunks without damage—a practical advantage when launching and retrieving. The tilted internal element automatically compensates for varying hull deadrises, eliminating the need for fairing blocks and simplifying installation on boats with aggressive bottom angles. At 1kW power output, the B175M delivers sufficient transmit energy for mid-range scanning and detailed target separation, making it ideal for depths from shallow flats to 200+ feet depending on water conditions and associated Garmin display unit.

Serious anglers upgrading existing Garmin systems will appreciate the 8-pin connector compatibility with legacy and current-generation fishfinders, ensuring seamless integration without expensive rewiring. Installation works best on transom-mounted applications where the 0° tilt orientation maximizes signal efficiency; the compact footprint suits boats where space constraints rule out larger bronze housings. This transducer suits both recreational and professional fishing operations where durability, minimal hull modification, and straightforward installation matter as much as sonar performance itself.
