Raymarine Bronze Thru-Hull Transducer w/ Fairing Block

Upgrade your boating experience with a reliable thru-hull transducer that delivers precise depth readings and speed data across a range of hull types. Designed for serious mariners who demand accuracy in challenging waters, this bronze model stands out for its robust construction and seamless integration with popular Raymarine displays.

Superior Dual-Frequency Performance

Operating at 50/200 kHz, this transducer provides versatile sonar coverage. The lower 50 kHz frequency excels in deeper waters, penetrating up to hundreds of feet to reveal fish, structure, and bottom contours. Switch to 200 kHz for high-definition imaging in shallower areas, perfect for coastal cruising or inland lakes. Paired with a 500W RMS power handling, it ensures clear, clutter-free returns even in turbulent conditions.

Bronze Build for Lasting Durability

Crafted from high-grade bronze, this thru-hull sensor thrives in saltwater environments where corrosion is a constant threat. Unlike plastic alternatives, bronze resists marine growth and degradation, maintaining peak performance season after season. It's ideal for fiberglass and wooden hulls up to several inches thick, offering a secure, flush mount that minimizes drag.

Integrated Speed and Temperature Sensing

The self-sealing paddle wheel insert measures boat speed through water and surface temperature with impressive accuracy. No more guessing your true speed—get real-time data unaffected by current or wind. The removable design allows for easy cleaning or winterization without hauling the boat, while the high-speed fairing block optimizes water flow for readings up to 40 knots.

Effortless Installation and Cable Management

With a standard 2-inch hole diameter, installation is straightforward for most vessels. The included 30-foot cable reaches distant helm stations, and the fairing block ensures proper alignment for maximum efficiency. Pro tip: Angle the fairing block 12-18 degrees based on your hull's deadrise to capture laminar flow, boosting speed sensor reliability at planing speeds.

Seamless Raymarine Integration

Engineered for Raymarine A, C, and E series multifunction displays, it pairs effortlessly with sounder modules like the DSM25. Whether you're running an A50D, A57D, or A70D, expect plug-and-play connectivity that unlocks CHIRP-like clarity without extra hardware. This setup shines for tournament anglers tracking bait schools or cruisers navigating reefs.

Real-World Reliability on the Water

Boaters report exceptional target separation in choppy seas, thanks to the streamlined bronze housing that sheds bubbles. The fairing block reduces turbulence, ensuring consistent depth and speed data during high-speed runs or tight maneuvers. For trailerable boats, the thru-hull design outperforms transom mounts by avoiding prop wash interference.

Maintenance for Peak Performance

Keep it performing like new with simple routines: Rinse after every saltwater outing to flush salt crystals. Annually inspect the paddle wheel for fouling—its self-sealing valve prevents leaks during removal. In cold climates, remove the insert to avoid freeze damage. With proper care, expect years of trouble-free service.
