Raymarine B744V Bronze Thru Hull Tri-Ducer w/Fairing Block

Upgrade your marine electronics setup with the Raymarine B744V Bronze Thru-Hull Tri-Ducer, a versatile multisensor that delivers precise depth readings, speed logs, and water temperature data all from a single, streamlined installation. Crafted from durable bronze, this transducer stands up to harsh saltwater environments while maintaining peak performance across a wide range of vessels, from sailboats to larger powerboats. Boaters trust it for its reliability during high-speed runs, where it continues to provide crystal-clear sonar images and accurate bottom tracking even beyond 30 knots.

Why Choose the B744V for Your Vessel?

The B744V shines in real-world boating scenarios, combining dual-frequency operation at 50 kHz for deep-water scanning up to 1200 feet and 200 kHz for detailed shallow-water views reaching 700 feet. Its integrated paddlewheel speed sensor offers GPS-independent speed-over-ground measurements, essential for precise navigation and performance tuning. Plus, the built-in temperature probe helps anglers identify thermal layers where fish congregate.

What sets this tri-ducer apart is its thoughtful engineering. The patented valve assembly acts like a safety net, sealing the hull instantly if you need to remove the insert for routine cleaning or winter storage—no more worrying about flooding risks. Pair it with the included high-performance fairing block, and you get a flush-mounted design that minimizes drag, ensuring your boat slices through water efficiently without compromising sensor accuracy.

Key Performance Highlights

• Dual-Beam Precision: 45° beam at 50 kHz for broad coverage in deep water; 12° beam at 200 kHz for pinpoint targeting in shallows.
• Versatile Mounting: Handles hull deadrises from 0° to 24°, making it suitable for most fiberglass and wooden hulls.
• Power Efficiency: Rated at 600 watts, it pairs seamlessly with popular Raymarine sounder modules for robust signal strength without overload.
• Extended Reach: 33-foot cable gives you flexible routing options during installation.
• Streamlined Fairing: High-speed block optimizes water flow over the sensor, reducing turbulence for better data at planing speeds.

Effortless Installation and Maintenance

Installing the B744V requires just a 2-inch hole through the hull, simplifying the process compared to multiple single-function sensors. Position it forward of the propeller and struts for optimal water flow, and angle the fairing to match your hull's deadrise. The self-sealing paddlewheel insert pops out easily for debris removal or servicing, keeping your setup maintenance-free and ready for action.

For best results, clean the sensor face regularly with a soft brush and marine-safe cleaner to prevent marine growth buildup, which can degrade performance. In colder climates, remove the insert to avoid freeze damage. This transducer's robust build and user-friendly design make it a favorite among DIY installers and professional riggers alike.

Real Boater Insights on Reliability

From coastal cruisers to offshore adventurers, users rave about the B744V's consistency. It excels in choppy conditions, maintaining lock on the bottom where lesser transducers falter. The bronze housing resists corrosion far better than plastic alternatives, ensuring years of trouble-free service. Anglers appreciate how the temp sensor reveals baitfish schools, while racers rely on the speed data for fine-tuning sails or props.

Seamless Integration with Raymarine Systems

Designed for compatibility with dedicated sounder modules, this tri-ducer slots right into your existing Raymarine ecosystem. It supports straightforward plug-and-play connections, letting you display depth, speed, and temp on multifunction displays without extra calibration hassles. Whether you're upgrading an older setup or building new, the B744V delivers pro-level data to inform every decision on the water.

Equip your boat with the Raymarine B744V and experience the difference in data accuracy and ease of use that keeps you safer and fishing smarter on every outing.
