Raymarine B744V 600W Bronze Thru-hull Transducer with Fairing Block

The Raymarine 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. The B744V is also available with a longer stem (B744VL) that may needed for steep-deadrise vessels or thick, cored hulls.
