Raymarine B175H-W 1KW Bronze Thru Hull 12° Tilted Element

Upgrade your boat's sonar capabilities with a transducer engineered for precision and durability in demanding marine conditions. This thru-hull model delivers crystal-clear underwater images, helping anglers spot fish, structure, and bottom contours with exceptional detail. Ideal for offshore adventures and competitive fishing, it transforms your display into a powerful tool for locating prime fishing spots.

Superior CHIRP Technology for Enhanced Fishfinding

At the heart of this transducer lies advanced CHIRP sonar, which sweeps across a broad frequency band to produce incredibly detailed returns. Unlike traditional fixed-frequency transducers, CHIRP provides superior target separation, sharper fish arches, and finer resolution of thermoclines and bait balls. Operating in the 150-250 kHz range, it excels at medium-depth scanning, revealing wrecks, reefs, and schools that narrower beams might miss.

The wide beam angle ensures broader coverage, making it perfect for scanning large areas quickly without sacrificing image quality. Anglers report consistently spotting structure and game fish at depths up to 800 feet, even in choppy waters where stability matters most.

Seamless Thru-Hull Installation with Tilted Element Design

Designed for hulls with 8 to 15-degree deadrise, the 12-degree tilted element aligns perfectly with your boat's contours, minimizing air bubble interference and maximizing bottom lock. This setup delivers reliable performance from takeoff, whether you're trailering to distant tournaments or cruising coastal waters.

Thru-hull mounting offers a clean, low-profile installation that withstands the rigors of saltwater exposure. The bronze housing provides excellent acoustic properties and corrosion resistance, ensuring long-term reliability. Pro tip: Pair it with a fairing block for deadrise angles at the upper end of the range to optimize water flow and reduce turbulence.

Rugged Build for Harsh Marine Environments

Crafted from high-grade bronze with a urethane face, this 1kW powerhouse is built to endure impacts, UV exposure, and constant submersion. Its robust construction supports fiberglass and wood hulls, making it a versatile choice for a wide range of recreational and light commercial vessels.

With a compact footprint and 6.6-foot cable, it integrates smoothly into existing systems. For longer runs, consider compatible extensions to reach your helm without signal loss. This durability translates to fewer downtimes and more time on the water chasing trophy catches.

Unlock Deeper Insights and Better Catches

Imagine dialing into precise depth and temperature readings while tracking fast-moving schools across a wide swath. This transducer shines in blue-water pursuits, where identifying pelagics like tuna or billfish amid bait pods can make or break your day. The 25-degree beam width at high frequencies captures expansive views, ideal for contour mapping and spotting drop-offs.

Integrated with modern multifunction displays, it supports dual-channel operation for simultaneous high and low-frequency views, giving you a complete picture of the underwater world. Fishers upgrading from older single-frequency units often notice immediate improvements in clarity and range.

Maintenance Tips for Peak Performance

To keep your transducer performing at its best, regularly inspect the face for marine growth and clean with a soft brush and mild cleaner. Avoid high-pressure washers that could damage the urethane. During haul-outs, store it protected from direct sunlight. Simple habits like these extend its service life, maintaining that edge in competitive scenarios.
