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

The Raymarine B744V Bronze Thru Hull Tri-Ducer with Fairing Block is a 600-watt through-hull transducer engineered for reliable depth, speed, and temperature readings on wood and fiberglass hulls. This marine sounder transducer delivers dual-frequency operation at 200/50 kHz, providing both shallow-water detail and deeper penetration for comprehensive bathymetric data across a wide range of fishing and cruising conditions.

Rated at 600 watts maximum power, the B744V generates strong sonar returns even in challenging conditions or at extended depths. The bronze through-hull housing resists corrosion in saltwater environments, while the fairing block minimizes turbulence and signal interference during high-speed operation. Installation requires a standard 2-inch hole diameter, and the unit ships with a 30-foot cable and connector ready for integration with compatible Raymarine sounder modules. The self-sealing removable paddle wheel insert simplifies maintenance and replacement without requiring haul-out.

This transducer is designed for cruising sailors, offshore anglers, and commercial operators who depend on real-time hull speed and temperature monitoring alongside depth capability. The B744V pairs exclusively with DSM30 and DSM300 sounder modules, making it an ideal upgrade or replacement for existing Raymarine systems. Weekend fishermen benefit from the speed and temperature data for finding thermal breaks and optimizing trolling patterns, while serious offshore operations leverage the multifrequency approach for improved target separation and wreck definition at depth.

Bronze through-hull transducers remain the industry standard for mixed-use vessels because they balance durability, signal quality, and installation flexibility. The Raymarine B744V's established compatibility with proven sounder electronics and proven performance in salt-water service makes it a straightforward choice for mariners upgrading or repairing depth and speed measurement systems.
