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

Discover Superior Underwater Visibility with the Garmin B175L Bronze Thru-Hull Transducer

Imagine gliding through open waters, effortlessly spotting fish schools, mapping the seafloor, and navigating obstacles with pinpoint accuracy. The Garmin B175L Bronze 20° Thru-Hull Transducer delivers exactly that, blending rugged durability with high-power sonar performance tailored for serious boaters. Crafted from corrosion-resistant bronze, this 1kW powerhouse thrives in saltwater environments, providing reliable depth readings up to 3,000 feet and temperature sensing without the bulk of traditional fairings.

Whether you're chasing trophy fish offshore or charting unfamiliar coastal waters, its 20° tilted element design adapts seamlessly to hulls with 16-24° deadrise angles. No more wrestling with custom fairings or compromising on signal quality—installation is straightforward, and the flush-mount housing barely protrudes (less than 1/4 inch), keeping your trailer bunks and rollers safe from damage.

Key Features That Set It Apart

  • High-Power 1kW Output: Captures detailed images in deep water, ideal for bluewater adventures where lesser transducers fall short.
  • Low-Frequency Excellence (40-60 kHz): Wide beam coverage (16-25°) ensures you scan broad areas efficiently, perfect for locating structure and bait balls from afar.
  • Integrated Depth and Temperature Sensor: Real-time data at your fingertips, helping you correlate water conditions with fish behavior.
  • 39-Foot Cable Length: Ample reach for versatile routing through your vessel's console.
  • 8-Pin Connector: Plug-and-play compatibility with a range of Garmin chartplotters and sounders.
  • Flush Bronze Housing: Minimal drag, maximum strength—built for fiberglass or wood hulls exposed to harsh marine conditions.

Why Boaters Trust This Transducer for Real-World Results

The secret lies in its thoughtful engineering. The internal 20° tilt compensates for hull angle, sending sonar pulses straight down for undistorted returns—no more weak signals from misalignment. Anglers report sharper bottom separation and fish arches even at high speeds, while cruisers appreciate the hassle-free setup that withstands trailering abuse.

Compared to pod-style mounts, this thru-hull option minimizes turbulence for cleaner data. It's a favorite upgrade for mid-to-large vessels, enhancing Garmin units like GPSMAP or echoMAP series with CHIRP-ready capabilities for future-proof scanning.

Streamlined Installation Tips for Peak Performance

  1. Site Selection: Choose a flat hull section forward of props and strakes for optimal water flow.
  2. Hole Prep: Use the included 2-inch shaft template; fair the edges for a watertight seal.
  3. Mounting: Secure with hull nuts, apply marine sealant—torque to spec to avoid leaks.
  4. Cable Management: Route away from electrical noise sources; strain relief prevents chafing.
  5. Calibration: Pair with your Garmin display and run bottom-tracking tests in shallow water.

Most installs take under two hours with basic tools, and the kit includes everything needed for a pro finish.

Frequently Asked Questions

What hull types work best with the Garmin B175L transducer?

It's optimized for fiberglass and wood hulls with 16-24° deadrise angles. The bronze housing resists corrosion in saltwater, making it unsuitable for aluminum without protection.

Does this transducer support CHIRP sonar?

Yes, its 40-60 kHz range pairs perfectly with Garmin's CHIRP-enabled fishfinders, unlocking wideband frequency sweeps for superior target resolution.

How deep can it scan reliably?

Expect solid performance up to 3,000 feet in ideal conditions, though bottom hardness and water clarity affect max range. Great for deep-sea fishing.

Is a fairing block required for installation?

No—the built-in 20° tilt eliminates the need for one, simplifying setup on angled hulls while maintaining beam alignment.

What Garmin displays is it compatible with?

It connects via 8-pin to most Garmin marine MFDs and dedicated sounders that support 1kW thru-hull inputs, including popular GPSMAP and ECHOMAP models.

Can it handle trailering?

Absolutely—the low-profile design protrudes less than 1/4 inch, safe for direct contact with trailer rollers or bunks.

Does it include a temperature sensor?

Yes, built-in temp sensing provides accurate surface water readings, essential for trolling speed adjustments and thermocline detection.
