Detailed description

The replacement insert for the AIRMAR B744V transducer is designed to restore the functionality of your through-hull multisensor. This TRIDUCER® provides depth, speed, and temperature data collection, essential for navigation and marine condition monitoring. It integrates a dual-frequency element (50/200 kHz) for versatile coverage.

Technical Performance and Versatility

With its dual frequency, this insert enables depth detection up to 366 meters (1200 feet) at 50 kHz, with a wide 45° beam, and up to 213 meters (700 feet) at 200 kHz, with a narrower 12° beam. The nominal power of 600 W RMS ensures reliable performance. The unit is compatible with fiberglass or wooden hulls and can be installed on keel angles up to 24° with a profiled shoe.

Design and System Integration

The AIRMAR B744V system features a through-hull bronze design and incorporates a urethane acoustic window. Its TRIDUCER® function combines the three sensors (depth, speed, temperature) into a single unit, requiring only one hull penetration. Design features include an automatic shut-off water valve that minimizes water flow into the hull when the paddlewheel insert is removed for maintenance, as well as lateral fins that improve speed accuracy in cross-flow conditions. The retractable insert simplifies maintenance. It is typically supplied with a 4.5-meter cable and is compatible with systems featuring a 10-pin Furuno connector, with an IP67 protection rating.

Expert opinion

« AIRMAR B744V insert: simplified maintenance for your TRIDUCER transducer »

This replacement insert for the AIRMAR B744V transducer is a critical technical solution for maintaining existing navigation systems. It is specifically designed for boat owners equipped with a B744V transducer, allowing them to extend the lifespan of their installation without replacing the entire through-hull transducer assembly. The main added value lies in the ability to replace the active element (including temperature transducers and speed paddlewheel) without major hull intervention. The depth sensor is located in the bronze body of the transducer and is not part of the replaceable insert.

Installation is simplified by the original design of the B744V, which includes a self-sealing valve. This means the insert can be replaced while afloat, though the self-sealing valve only minimizes water flow and does not provide a watertight seal. This operation reduces maintenance costs and complexity. Simply remove the old insert and insert the new one. The main constraint is routing the new 4.5-meter cable from the insert, which must be spliced to the existing transducer cable (which may feature a 10-pin Furuno connector) leading to the onboard electronics.

This product differs from complete transducers by serving as a strategic replacement part. It is designed for repairs rather than new installations, offering an economical and practical alternative to full transducer replacement. It is particularly relevant for boats up to 9 meters where the B744V transducer is commonly installed. It is essential to ensure the insert is fully compatible with the existing B744V transducer body and that the 10-pin connector matches the onboard electronic equipment.

Frequently Asked Questions

Need help? Contact us

What is the AIRMAR B744V replacement insert?

This is a replacement insert specifically designed for the AIRMAR B744V through-hull multisensor transducer. It restores depth, speed, and temperature functionality to your marine navigation system.

What are the main functions of this depth sounder insert?

This insert is a TRIDUCER®, meaning it combines three essential functions: depth detection, boat speed through water measurement, and water temperature measurement.

Which frequencies does the AIRMAR B744V transducer use?

The transducer uses dual frequencies: 50 kHz and 200 kHz. This dual-frequency setup provides versatility for different depths and detection types.

What is the nominal power rating of this depth sounder insert?

The rated power of this transducer insert is 600 W RMS, ensuring reliable performance for marine data detection and collection.

What is the maximum depth the transducer can detect at 50 kHz?

At 50 kHz, the transducer can detect depth down to 366 meters (1,200 feet), with a wide 45° beam.

What is the depth detection capability at 200 kHz?

At 200 kHz, depth detection is possible down to 213 metres (700 feet), with a narrower 12° beam.

Why is the insert described as 'retractable'?

The insert is retractable to facilitate maintenance. This design allows you to remove it for servicing without having to take the boat out of the water, thanks to an automatic water shut-off valve.

What is the function of the automatic shut-off seawater valve?

The automatic shut-off water valve minimizes water flow into the hull when the impeller is removed for maintenance, ensuring boat safety and simplifying upkeep.

What are the side fins on the insert used for?

The side fins are designed to improve the accuracy of the boat speed measurement, especially in conditions of cross-flow of water.

Which type of transducer is this insert compatible with?

This insert is specifically designed as a replacement for the AIRMAR B744V through-hull transducer. It is essential to verify that your existing transducer is indeed a B744V to ensure compatibility.

Which hull materials is this insert compatible with?

The AIRMAR B744V replacement insert is compatible with fiberglass or wooden boat hulls.

What type of connector is supplied with this insert?
