Raymarine BTH Tri W/Block B744V Housing

The Raymarine BTH Tri W/Block B744V Housing is a professional-grade through-hull transducer designed for serious anglers and boaters who demand reliable sonar performance in both freshwater and saltwater environments. After years on the water, any experienced angler knows that transducer quality directly impacts fish detection and navigation accuracy—this Raymarine unit delivers the dependability needed for consistent, season-after-season performance. Built for integration with Raymarine's DSM30 and DSM300 sounder modules, this transducer system transforms your fishfinder into a precision tool for locating structure, thermoclines, and game fish at depth.

The B744V housing utilizes a rugged through-hull mount design compatible with both wood and fiberglass hulls, eliminating the guesswork during installation. Operating at dual frequencies—200 kHz for detailed near-bottom resolution and 50 kHz for deep-water reach—this transducer provides the flexibility to adjust your sonar picture based on depth and bottom composition. With 600 watts of peak power output, the Raymarine BTH Tri W/Block B744V Housing cuts through noise and delivers crisp, clean returns even in challenging conditions like heavy weeds, rocky bottoms, or murky water where lesser units falter. The tri-frequency capability is particularly valuable when transitioning between shallow bays and offshore depths during a single outing.

This transducer is ideal for boat owners upgrading existing Raymarine systems or building a new fishfinding setup from the ground up. The 10-pound weight and through-hull configuration mean permanent, noise-free mounting once installed—no suction cups to fail or transducers fouling on weeds mid-trip. Whether you're a tournament angler chasing walleye and bass, a striped bass hunter working tidal flats, or a recreational boater seeking reliable bottom-mapping capability, the Raymarine BTH Tri W/Block B744V Housing integrates seamlessly with compatible Raymarine sounder modules to deliver tournament-grade sonar imaging for your vessel.
