The Raymarine B744V is a bronze thru-hull triducer combining speed, depth, and temperature sensing in a single installation. Designed for wood and fiberglass hulls, it operates at 200 kHz and ships with a generous 45-foot cable to reach most helm locations without extension. Compatible with Raymarine ST60+, ST290, and ST70 instrument systems — note that ST70 use requires the separately sold ST70 Speed Pod and ST70 Depth Pod. A fairing block (E66023) is also available separately for optimized water flow alignment.
