AIRMAR B744V 50/200kHz 600W Thru-Hull TRIDUCER® Multisensor — Garmin 8-Pin, DST
The AIRMAR B744V is a bronze thru-hull TRIDUCER® Multisensor with a 600W dual-frequency ceramic element and a Garmin 8-pin connector, weighing 5.5 lbs.
The unit combines depth, speed, and temperature sensing in a single housing
, and is installed by marine electronics technicians and vessel owners fitting fiberglass or wood hulls with Garmin fishfinder or chartplotter systems.

Compatibility & Applications
- Fits fiberglass or wood hull vessels requiring a thru-hull DST transducer.
- Pairs with the included High-performance Fairing for bottom tracking at speeds up to 30 knots (34 MPH).
- Wires to 6-pin Garmin sounders using Garmin adapter cable part number 010-11612-00 (sold separately).
- Connects to Garmin echo 101, echo 151, echo 301c, echoMAP 50dv, echoMAP 70dv, GPSMAP 1020xs, and GPSMAP 451s units, among others.
- The companion model B744VL (longer stem) mounts in steep-deadrise vessels or thick cored-fiberglass or wood hulls.
- Self-closing water valve reduces hull water flow when the paddlewheel insert is being replaced; fins on the paddlewheel cavity sides improve accuracy in cross-flow conditions.
Mounted through the hull of a center console or sportfish running up to 30 knots, the B744V delivers depth to 1,200 ft at 50 kHz and 700 ft at 200 kHz from one bronze housing —
the only thru-hull transducer offering depth, speed, and temperature in one package
for Garmin 8-pin sonar systems.
