Raymarine - B744V Bronze Thru Hull Tri-Ducer w/Fairing Block - A66091

Operating at both 50 kHz and 200 kHz, the B744V TRIDUCER Multisensor provides you with depth, speed, and temperature in one thru-hull housing. This unit is ideal for all 600-Watt fishfinders and requires only a single hole in the hull.

The B744V's patented valve assembly prevents water from rushing into the hull when the insert is removed for cleaning or storage. 

The innovative housing design allows the TRIDUCER Multisensor to be fully recessed into its custom High-Performance Fairing. The end result is a streamlined installation. At speeds above 30 knots (34 MPH), the B744V will produce clear images and solid bottom tracking!
