Overview
600 W 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).
