Description
Garmin B744VL Bronze Thru-Hull Transducer | Boat Supply Store
This Airmar B744VL transducer integrates critical depth, speed, and temperature sensing into a single, robust bronze thru-hull unit. It operates at dual frequencies, 50 kHz and 200 kHz, for versatile underwater target resolution and environmental data acquisition. Engineered for vessels with hull deadrise angles from 0 to 28 degrees, it ensures accurate readings even in varied sea conditions. The long stem design facilitates installation in thicker hull materials or on boats with pronounced hull forms.

Common Concerns Answered
How accurate is the speed reading?
Speed readings from the B744VL can exhibit reduced accuracy in extremely low speeds or turbulent water conditions. For precise speed data in all conditions, consider dedicated paddlewheel or GPS speed sensors.
What Garmin displays are compatible with the B744VL transducer?
This transducer requires a compatible Garmin display unit equipped with an 8-pin transducer port. Always verify specific model compatibility through Garmin's official documentation or our support team.
Is installation difficult?
Installation of a thru-hull transducer involves drilling a hole through the vessel's hull and ensuring a watertight seal. This process is rated at an InstallDifficulty of 3, recommending basic DIY skills or professional installation for optimal results.
Frequently Asked Questions
What type of boat is the Garmin B744VL Long Stem Bronze Thru-Hull Depth/Temp/Speed w/FB - 8 Pin suitable for?
