Airmar B744VL Transducer Bronze Long Stem Dual Frequency

Overview

Who This Is For: Built for serious anglers and cruisers running fiberglass or wood hulls with steep deadrise angles or thick hull construction. If you've got a performance boat that planes hard and you need depth, speed, and water temperature all in one transducer, this is your solution.

The B744VL is a three-in-one thru-hull transducer that handles depth, speed, and temperature with a single bronze housing and extended stem. Dual 50/200 kHz frequencies give you shallow-water detail at 200 kHz and confident deep-water tracking down to 1,200 feet at 50 kHz. The long stem is purpose-built for boats with deadrise angles up to 24 degrees or thick, cored hulls where standard transducers won't reach through-hull properly. Pair it with the included high-performance fairing and you'll get solid sonar tracking at speeds up to 30 knots without signal breakup.

Key Features

• Dual-Frequency Sonar (50/200 kHz) — gives you a 45° wide beam for dependable bottom tracking in deep water at 50 kHz, and a tight 12° beam at 200 kHz for crisp target separation in shallow water — you get both shallow and deep coverage in one transducer.
• Extended Long Stem — sits proud of thick, cored fiberglass and wood hulls where standard transducers can't reach — critical if your hull is built for durability or your deadrise angle is steep.
• Depth, Speed, and Temperature in One Housing — eliminates multiple thru-hull penetrations and reduces clutter below decks — one hole, three critical data feeds.
• High-Performance Fairing — keeps sonar clean and stable at cruise and plane speeds up to 30 knots — no signal drop-out when you're pushing it.
• Self-Closing Water Valve — lets you swap the paddlewheel insert for a blanking plug without flooding the bilge — practical maintenance without the stress.
• Cross-Flow Compensation Fins — stabilizes speed readings in beam seas and crosswind conditions — your speed data stays accurate even when conditions get sloppy.
• 600 W Power Output — enough punch to cut through mineralized or turbid water and still paint a clean picture on your fish finder — especially valuable in Great Lakes or coastal systems.

Specs & What's Included

Compatibility: This transducer works with fish finders and chartplotters equipped with an 8-pin connector supporting depth/speed/temperature functionality. Verify your display unit accepts a TRIDUCER Multisensor before ordering. Not sure if this works with your setup? Call or text us at (833) 831-4077 — we'll tell you straight.

In the Box: B744VL transducer with extended stem, high-performance fairing, and 8-pin connector. Installation hardware sold separately. Requires a 51 mm (2-inch) thru-hull hole.
