Airmar B744VL Thru-Hull Dual Frequency Triducer Multisensor

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. The required High-performance Fairing gives excellent results at speeds up to 30 knots (34 MPH).

Features:

• Depth, speed, and fast-response water-temperature sensing in one housing
• 600W of power
• Dual-frequency element:
  • 50 kHz with a wide 45° beamwidth for depth performance to 1200' (353 m)
  • 200 kHz with a 12° beamwidth for depth performance to 700' (206 m)
• 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 the paddlewheel insert is being replaced with the blanking plug
• Fins on sides of paddlewheel cavity improve accuracy in cross-flow conditions
