Raymarine B744VL Long Stem DST Thru Hull Transducer (No Fairing)

• Depth speed and temperature in one housing
• 600 W
• Dual-frequency element:
• 50 kHz with a wide 45° beamwidth for depth performance to 353 m (1 200')
• 200 kHz with a 12° beamwidth for depth performance to 206 m (700')
• Extra-long stem for thick or steep-deadrise hull
• Bronze housing with a high-performance fairing for optimal bottom tracking at higher speeds
• Self-closing water valve reduces water flow into the hull when paddlewheel insert is removed
• Fins on sides of paddlewheel cavity provide improved accuracy in cross flow conditions

The B744VL is a TRIDUCER Multisensor featuring depth speed and temperature in a single housing. The 50/200 kHz dual-frequency single ceramic element provides great target detail in shallow water at 200 kHz and good deep-water bottom tracking at 50 kHz. The B744VL's extended stem-length has the extra height needed for steep-deadrise vessels or thick cored-fiberglass or wood hulls.
