Garmin B175M Bronze 20° 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. Engineered for seamless integration into fiberglass or wood hulls, its innovative 20-degree tilted element adapts effortlessly to hull deadrises between 16 and 24 degrees, ensuring optimal sonar performance without the hassle of additional fairing blocks. The flush-mounted bronze housing extends just a fraction of an inch beyond the hull—less than 1/4 inch—making it trailering-friendly and resistant to damage from rollers or bunks.
Delivering CHIRP technology in the medium frequency range of 85-135 kHz at 1kW power, this transducer paints a crystal-clear picture of the underwater world, from shallow structures to depths up to 3,000 feet. Paired with temperature sensing, it provides essential data for navigation, fish targeting, and safety in diverse marine environments.
Standout Features for Superior Performance
- CHIRP Medium Frequency Excellence: Operates at 85-135 kHz, capturing wide beam widths of 11-16 degrees for detailed imaging across varied depths.
- Tilted Element Design: Built-in 20-degree tilt compensates for hull angles, maximizing signal strength and minimizing air bubbles or distortion.
- Rugged Bronze Construction: Corrosion-resistant housing thrives in saltwater, with a low-profile mount that withstands trailering abuse.
- Integrated Sensors: Accurate depth readings up to 3,000 feet plus water temperature monitoring—no extra probes needed.
- Easy Connectivity: 8-pin interface plugs directly into compatible Garmin sounders, with a generous 39-foot cable for flexible routing.
- Versatile Hull Compatibility: Ideal for deadrises of 16-24 degrees; includes a 2-inch shaft and straightforward installation hardware.
Why Boaters Choose This Transducer
Unlike traditional fixed transducers that demand custom fairings or struggle with hull shapes, this model's pre-tilted element delivers pro-level results out of the box. Anglers report sharper fish arches, better bottom separation, and reliable target separation even in rough seas or thermoclines. Its 1kW power punches through murky water, revealing wrecks, drop-offs, and schools that lower-wattage units miss.
For offshore adventures, the extended 3,000-foot depth capability means you're equipped for bluewater pursuits, while coastal cruisers appreciate the temperature data for locating bait balls and current edges. The bronze material ensures longevity in harsh conditions, reducing maintenance headaches and keeping you on the water longer.
"Switched to this from a basic thru-hull and the difference in clarity is night and day—fish hold on screen like never before." – Experienced offshore angler

Pro Installation Tips for Peak Performance
- Site Selection: Choose a flat hull section forward of the propeller, away from strakes or thru-hulls that cause turbulence.
- Angle Check: Verify your hull's deadrise falls within 16-24 degrees; the 20-degree tilt handles most without shimming.
- Sealing: Use marine sealant around the housing for a watertight fit—critical for saltwater reliability.
- Cable Management: Route the 39-foot cable through existing conduits, avoiding sharp bends to prevent signal loss.
- Testing: After install, run at displacement speed first to confirm no aeration; adjust if needed.
Most DIYers complete the job in under two hours with basic tools, but consult your boat's manual for specifics.
Frequently Asked Questions
What hull types is this transducer best suited for?
It's optimized for fiberglass and wood hulls with deadrises from 16 to 24 degrees. The bronze construction handles saltwater exposure exceptionally well.
Does it require a fairing block for installation?
No, the built-in 20-degree tilted element eliminates the need for a fairing block, simplifying setup on most hull shapes.
What's the maximum depth it can detect?
Up to 3,000 feet, making it suitable for both inshore and deep offshore applications with CHIRP clarity.
Is temperature sensing included?
Yes, it provides reliable water temperature data alongside depth, aiding in fish location and navigation.
How trailering-friendly is the housing?
Extremely—the flush mount protrudes less than 1/4 inch, safe for trailer rollers and bunks without risk of damage.
What Garmin units is it compatible with?
It connects via 8-pin to Garmin chartplotters and sounders supporting 1kW CHIRP transducers in the medium frequency band.
Can it detect speed through water?
This model focuses on depth and temperature; speed log functionality requires a separate paddlewheel sensor.
