Airmar B744V Thru-Hull Dual Frequency Triducer Multisensor

The B744V 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.

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)
• 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
