Garmin B175L Bronze 12° Thru-Hull Transducer - 1kW, 8-Pin
Garmin B175L Bronze 12° Thru-Hull Transducer - 1kW, 8-Pin — Product description
Discover the power of precise underwater detection with this high-performance thru-hull transducer designed for serious anglers and boaters chasing big game in deep waters. Engineered with a low-profile bronze housing, it mounts flush to your hull, extending just a fraction of an inch below the surface—perfect for trailering without worry over bunks or rollers scraping it up.
What sets this model apart is its innovative 12-degree tilted element. This smart design automatically compensates for your boat's deadrise angle, from 8 to 16 degrees, skipping the hassle and extra cost of custom fairing blocks. Whether you're running a sleek fiberglass racer or a sturdy wooden cruiser, installation stays straightforward and effective.
Superior Deep-Water Performance
Operating at a robust 1kW power level across a wide 40-60 kHz frequency range, this transducer excels at penetrating depths up to 3,000 feet. The expansive 16-25 degree beam width at -3dB captures vast swaths of the water column, revealing structure, bait balls, and trophy fish lurking far below.
- CHIRP-Ready Low Frequency: Tuned for long-range scanning, ideal for offshore trolling or canyon hunting where every foot counts.
- Integrated Temperature Sensor: Tracks water temp changes to pinpoint thermoclines and fish-holding zones.
- Max Depth Capability: Reliable returns from 3,000 feet, outpacing many standard setups.
Built for Real-World Boating Demands
Crafted from corrosion-resistant bronze, this 8-pin transducer laughs off saltwater abuse season after season. The 39-foot cable gives you flexible routing options during install, reaching from bow-mounted plotters to stern electronics without strain.
| Frequency (kHz) | Power | Beam Width (°) | Max Depth (ft) | Sensors | Pins | Deadrise Angles |
|---|---|---|---|---|---|---|
| 40-60 | 1kW | 16-25 | 3,000 | Depth + Temp | 8 | 8-16° |
Effortless Installation and Compatibility
Thru-hull mounting keeps wiring clean and performance optimal, with detailed instructions included to guide you through. Pair it seamlessly with popular marine multifunction displays supporting 8-pin transducers—no adapters needed. For hulls up to 16-degree deadrise, the pre-tilted ceramic ensures a dead-on beam perpendicular to the waterline, maximizing target separation and bottom tracking.
Why Boaters Trust This Setup
Skip the guesswork on fairings or pod mounts that drag fuel efficiency. This low-protrusion design hugs the hull for minimal drag, while the bronze build handles the pounding of bluewater runs. Anglers report crystal-clear images of wrecks and reefs at extreme depths, turning ordinary outings into record hauls.
