A26044 B744VL Bronze Transducer Depth / Speed / Temperature

The A26044 B744VL is a bronze transducer with an extended housing (Long Stem), designed to meet the needs of vessels with thicker hulls or significant deadrise. With an extra 2.5 inches of stem length compared to the standard B744V, this model can be installed so that its sensors sit optimally deep in the water flow beneath the boat, ensuring constant contact with water and precise measurements.

• Ideal for thick or cored hulls: If your boat has a cored hull, extra interior liners, or simply a greater hull thickness, the B744VL provides the length needed to pass through all layers and achieve a proper installation. The extended stem (approximately 140 mm usable length) prevents the retaining nut from burying into the hull and makes sealing easier on thick structures.
• Suitable for deep-V hulls: On boats with a pronounced V-shaped bottom (especially larger power yachts), the B744VL can be mounted using a fairing block such that the sensor faces straight down. Its longer form allows it to overcome the curvature of the hull, keeping the sensing elements in the optimal position for accurate data.
• Complete navigation data: Like the B744V, this triducer provides three key parameters – depth, speed, and temperature. Connected to an appropriate sonar module (for instance, a Raymarine DSM or CP370) or via an iTC-5 into an instrument system, it delivers reliable information about the underwater environment and the vessel’s performance. Its 600 W depth element operates at 50/200 kHz, enabling deep water sounding capability when needed.
• Comprehensive install kit and integration: The B744VL comes with an installation kit, including gaskets and nuts sized for the extended profile. The 14 m cable with connector ensures ample reach to your electronics, even when the transducer is far from the helm. The additional body length doesn’t change maintenance routines – you should clean it periodically to remove marine growth, just as you would with any thru-hull sensor.

With A26044 B744VL, boat owners gain the flexibility to mount a rugged and accurate sensor even in challenging hull configurations. It is the recommended choice for larger vessels where standard transducers fall short or don’t perform optimally. By investing in this long-stem bronze transducer, you ensure a continuous stream of vital data and durability that’s ready for long voyages on the open ocean.
