XSONIC Airmar B744V depth sounder with speed and temperature NMEA 2000

The XSONIC Airmar B744V is a TRIDUCER® Multisensor that combines three essential functions in a single through-hull housing: depth, speed, and water temperature measurement. It is designed for full integration of navigation data.

The XSONIC Airmar B744V transducer delivers a transmit power of 600 W, providing good performance for depth detection and underwater structure identification.

The B744V transducer is a dual-frequency transducer, operating at 50 kHz and 200 kHz. This duality allows it to adapt to various fishing and navigation conditions, providing deeper penetration at 50 kHz and higher detail resolution at 200 kHz.

The B744V transducer can reach a maximum depth of 366 metres (1,200 feet) at 50 kHz and 213 metres (700 feet) at 200 kHz, providing excellent detection capability for varying water depths.

The B744V transducer housing is made of bronze. This material is recommended for fiberglass or wooden hulls. It is important to note that a bronze housing must never be installed on a metal hull due to the risk of electrolytic corrosion.

The B744V transducer measures water speed within an operational range of 1 to 45 knots (1 to 52 mph).

Yes, the XSONIC Airmar B744V transducer is supplied with a 10-metre cable, fitted with a 9-pin sonar connector.

The B744V transducer offers a 45° beam angle at 50 kHz and a 12° beam angle at 200 kHz. These angles provide wide coverage for fish detection at 50 kHz and more targeted, detailed detection at 200 kHz.

Yes, the B744V probe is a TRIDUCER® Multisensor. This means it combines depth, speed, and temperature functions in a single housing, requiring only one hole in the hull for installation.

Yes, the impeller insert in the paddlewheel that measures speed and temperature is removable. This makes maintenance, cleaning, or replacing the insert easier without having to remove the entire depth sounder from the hull.

The XSONIC Airmar B744V transducer, with its bronze housing, is compatible only with fiberglass or wooden hulls. It is imperative never to install it on a metal hull to avoid electrolytic corrosion.

Yes, the B744V transducer is NMEA2000-compatible for speed and temperature data. The impeller insert transmits this information via the NMEA2000 network, enabling easy integration with compatible displays and navigation systems.

The B744V transducer is recommended for boats with an overall length up to 9 metres (30 feet).

The B744V transducer can be installed on boats with a keel angle up to 24°, provided you use its high-performance fairing shoe, which compensates for hull tilt.

Installing the B744V transducer requires drilling a single 51 mm (2 inch) hole in the boat's hull.

Yes, installing a high-performance fairing block is mandatory for the B744V transducer. The fairing block ensures an adequate sealing surface around the drilled hole and optimizes probe performance by maintaining a steady water flow.

To ensure perfect watertightness, all O-rings in the insert must be intact and properly lubricated. The impeller insert or blanking plug must be securely fastened with its nut and locking wire. The integrated valve is not a watertight seal on its own.

Yes, thanks to the integrated valve, the impeller insert can be removed for maintenance or cleaning without having to take the boat out of the water. However, it is critical never to remove the CAP nut, as this would disengage the entire valve assembly, compromising watertight integrity.

Yes, it is mandatory to attach the safety lanyard to the impeller insert. This lanyard prevents the insert from accidentally disengaging in the unlikely event that the insert or valve nut loosens or is improperly tightened, providing additional protection against leaks.

When trimming the keel shoe, it is essential to measure the hull's keel angle and cut the shoe at that precise angle. The shoe must be installed parallel to the keel to ensure proper boat support. There should be no gap larger than 3 mm (1/8") between the shoe and the hull, and the transducer must be flush with the shoe for optimal water flow.
