Airmar B744VL 600W 50/200 kHz Thru Hull Triducer with Fairing Block for Lowarance and Simrad Long Stem

Fits: Lowrance and Simrad units with blue collar connector, HDS, LCX, NSE, NSO, NSS

The B744VL’s extended stem-length has the extra height needed for steep-deadrise vessels or thick-hulled wooden boats.

The B744VL TRIDUCER® Multisensor provides you with depth, speed, and temperature in one thru-hull housing. This unit is ideal for all 600 W fishfinders and requires only a single hole in the hull.

The B744VL’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 B744VL will produce clear images and solid bottom tracking!
