Airmar B744V – bronasta prečna sonda 600W (50/200kHz) z nosilcem + hitrost površine + temperatura – (8 priključkov)

The Garmin Airmar B744V transducer has an RMS power output of 600W. This power enables it to provide high-quality data for various freshwater and coastal fishing applications.

The Airmar B744V fishfinder operates on two frequencies:

50 kHz: for wide coverage and fish school detection.
200 kHz: for precise seabed structure definition and better target separation.

The Garmin Airmar B744V is a multisensor transducer that provides depth, surface speed, and water temperature data. It offers a compact solution that minimizes the number of hull penetrations required.

The Airmar B744V transducer is designed for boats up to 9 meters in length. It is suitable for fiberglass or wooden hulls.

The B744V transducer provides bottom detection up to:

366 metres (1200 feet) at 50 kHz frequency.213 metres (700 feet) at 200 kHz frequency.

The Airmar B744V transducer offers the following beam angles:

A 45° beam at 50 kHz, providing wide coverage.A 12° beam at 200 kHz, offering precise definition.

The Airmar B744V transducer guarantees reliable surface speed measurements even at high speeds, with excellent results up to 30 knots (34 MPH). This is particularly beneficial for planing hulls where signal stability is critical.

The Airmar B744V transducer housing is made of bronze. This material is recommended for fiberglass or wooden hulls.

The Airmar B744V transducer, with its bronze housing, is specifically recommended for installation on fiberglass or wooden hulls.

No, the Airmar B744V transducer must never be installed on a metal hull. The bronze housing of the sensor would cause electrolytic corrosion with a metal hull, potentially causing serious damage to the boat.

The Airmar B744V transducer is equipped with an 8-pin connector. This information is essential to ensure compatibility with your Garmin fishfinder or multifunction display.

Yes, installing a fairing (High-Performance Fairing) is mandatory with the Airmar B744V transducer. A fairing carefully cut to match the hull shape ensures a watertight surface around the drilled hole. Without a fairing, the watertight surface may be insufficient, leading to water leaks in the boat.

During installation, the following precautions must be taken:

Always wear safety glasses, a dust mask, and hearing protection.Immediately check for leaks when the boat is launched and do not leave it unattended for more than three hours.Never pull, carry, or hold the transducer by its cable to avoid damaging internal connections.Always operate the transducer in water; running it in air can cause overheating and failure.Never strike the transducer.Never use solvents, cleaners, fuel, or products containing solvents that could damage plastic parts.Never sand or clean the transducer with a pressure washer.

To choose the best mounting location, follow these guidelines:

Ensure the water flow under the hull is smooth, with minimal bubbles and turbulence, especially at high speed.The transducer must remain continuously immersed in water at all speeds.The transducer beam must not be obstructed by the keel or propeller shaft.Select a location away from interference sources such as propellers, shafts, other machinery, other fishfinders, and other cables.For displacement hulls, mount it at 1/3 of the waterline length and 150-300mm (6-12") from the centerline.For planing hulls, install it well aft near the centerline and inside the first lifting strakes.

Yes, it is crucial to avoid the following locations:

In line or near water intakes or discharges.Behind strakes, fittings, or hull irregularities that could disrupt water flow.Where the boat may be supported during towing, launching, hauling, or storage to prevent damage to the transducer face.

To ensure a perfect watertight seal:

The fairing must be carefully trimmed to fit the hull shape and must not have a gap larger than 3mm (1/8") between it and the hull.The anti-rotation bolt of the fairing is mandatory and must be installed.All O-rings on the impeller insert must be intact and properly lubricated with the supplied silicone grease before insertion.The impeller insert or blanking plug must be securely fastened with the insert nut and locking wire. The valve alone does not provide a watertight seal.Use marine sealant suitable for below-the-waterline applications.

Yes, it is essential to lubricate all O-rings on the impeller wheel insert. They must be intact and properly lubricated with the provided silicone grease to ensure a watertight seal. Attempting to install the insert without adequate lubrication can damage the O-rings and prevent full insertion and proper sealing.

Yes, the B744V transducer is designed to allow removal of the impeller insert for maintenance, cleaning, or replacement without having to remove the entire transducer from the hull. However, it is critical not to remove the CAP nut, as the entire valve assembly would come out. The insert or blanking plug cannot be secured without the valve assembly.

During installation, the end of the fairing with the arrows or triangular recess must always point forward (toward the bow) of the boat. It is also important to ensure the fairing is installed parallel to the keel to guarantee proper course-keeping.
