AIRMAR® B744V Triducer

“I upgraded to the Garmin GT56UHD and the clarity is unbelievable. You can literally see fish moving around structure. Hard Rig Marine helped me pick the right setup and it’s been spot on since day one.”
Michael R. — Cairns, QLD -
“I’m not a tech person, but the team made it super easy to install my GT54UHD transducer. Works perfectly with my ECHOMAP — I’ve never had sonar this clear in the estuary before!”
Jenny L. — Mandurah, WA -
“The Airmar B175M changed my whole deep drop setup. Way better definition and stability compared to my old transducer. You get what you pay for — and these guys know their stuff.”
Ben T. — Newcastle, NSW
AIRMAR® B744V TRIDUCER: Depth, Speed, & Temp Thru-Hull (600W)
The AIRMAR® B744V is the ultimate **Triducer**—the only thru-hull transducer that provides simultaneous **Depth, Speed, and Water Temperature** data in one robust bronze housing. This 8-pin unit features reliable **600 W Traditional Sonar** operating at **50/200 kHz** dual frequencies. It delivers stable performance and deep-water capability, with depth returns ranging from **800 to 1,200 feet**. The B744V is ideal for cruising and sport fishing boats requiring comprehensive instrumentation data alongside strong traditional sonar.
ALL-IN-ONE INSTRUMENTATION & SONAR
The B744V simplifies installation by consolidating three critical sensors into one unit, ensuring clear data transmission to your Garmin Chartplotter.
KEY SONAR & INSTRUMENTATION FEATURES
- Triducer Functionality: Provides three data types—**Depth, Speed (Paddelwheel), and Water Temperature**—through a single thru-hull fitting.
- Traditional Sonar: 600 W power using **50/200 kHz** frequencies, balancing deep penetration with high-resolution detail (800–1,200 ft depth).
- Wide Deadrise Support: Configurable for hull deadrise angles from **0 to 24 degrees** (requires fairing block for correction).
- Bronze Housing: Durable bronze construction is ideal for **fiberglass and wood hulls** (Do not use on metal hulls).
INSTALLATION AND CONNECTIVITY
The B744V requires a fairing block for beam alignment and connects using the standard 8-pin Garmin plug.
- **8-Pin Connector:** Uses the 8-pin connector for power, sonar, and instrument data output.
- **Cable Length:** Includes a robust **39-foot cable** for flexible routing on larger vessels.
- **Legacy Compatibility:** When using with older 6-pin Garmin sounders, an adapter cable is required.
Inverell Boating Centre Expert Note:
The AIRMAR B744V is a dedicated 600W Traditional Sonar unit (no scanning capability). Its Triducer status—combining depth, speed, and temperature—is highly valued for simplifying hull penetration. This transducer is optimized for reliable depth performance (up to 1,200 ft) and requires **professional installation** due to the thru-hull design and need for deadrise compensation via the included fairing block.
