XSONIC Airmar B175H-W (12°) (1.8 m - Boatbuilder)

The XSONIC Airmar B175H-W (12°) transducer is a 1 kW CHIRP transducer designed for underwater detection, depth measurement, and water temperature monitoring. It uses high-band CHIRP technology for optimal performance.

The B175H-W (12°) transducer operates in the high-band CHIRP frequency range, from 150 kHz to 250 kHz. This provides a total bandwidth of 100 kHz for detailed detection.

This transducer features a constant wide beam of 25°. This characteristic provides coverage under the boat twice that of high-frequency narrow-beam transducers, improving fish detection and visibility in the water column.

The XSONIC Airmar B175H-W (12°) transducer can reach a maximum depth of 152 meters (500 feet), providing superior resolution and detail for target identification and seabed structure.

The B175H-W (12°) transducer housing is made of bronze, making it suitable for fiberglass or wood hulls.

The bronze housing of this depth sounder is recommended for fiberglass or wooden hulls. It must never be installed in an aluminum hull, as this would cause electrolytic corrosion.

This transducer features a 12° tilted element, compensating for keel angles from 8° to 15°. This ensures the sonar beam is vertically oriented for maximum echo returns.

The XSONIC Airmar B175H-W (12°) transducer is supplied with a 1.8-metre (6-foot) cable and features a 9-pin connector.

The integrated Xducer ID® technology enables automatic and optimized configuration of the transducer with compatible devices, simplifying installation and use.

A CHIRP wide-beam transducer, like the B175H-W, provides extended coverage beneath the boat, increasing the chances of detecting fish in the water column. It also delivers superior resolution and precise details for target identification and bottom structure.

For installation, you will need safety glasses, a dust mask, hearing protection, a protractor, an electric drill, a 3mm (1/8") drill bit, a 95mm (3-3/4") hole saw for fiberglass or wooden hulls, sandpaper, mild detergent or a weak solvent (alcohol), marine sealant, and a 3/16" Allen key.

The transducer must be mounted in an area where the water flow under the hull is smooth, with minimal bubbles and turbulence. Ensure it is continuously submerged and that its beam is not obstructed by the keel or propeller shafts. Select a location away from sources of electrical interference and accessible from inside the boat with at least 178 mm (7") of clearance.

For fiberglass or wooden hulls, a 95 mm (3-3/4") hole saw is required to cut the installation hole. A 3 mm (1/8") pilot hole must be drilled first.

CHIRP transducers generate more heat than traditional transducers. It is crucial to mount the transducer in a cool, well-ventilated area, away from the engine compartment or other heat sources. Additionally, the transducer must always operate while submerged in water; operating it in the air can lead to overheating and failure.

To protect your depth sounder from marine fouling, you can apply a Foulfree coating. This non-toxic, durable and ultra-smooth coating prevents marine growth from adhering to the surface. Airmar certifies that applying Foulfree does not result in any loss of transducer performance.

Yes, the XSONIC Airmar B175H-W transducer is a hardware accessory compatible with Lowrance systems, including sonars, sensors, transducers, and antennas that support Airmar Tilted Element transducers.

Yes, this transducer can be used with all types of boat propulsion, whether outboard, inboard, or I/O systems.

Yes, it is important not to install the transducer in line or near water discharge outlets, or behind hull strakes, fittings, or surface irregularities that could disrupt water flow. Smooth water flow is essential for optimal performance.

The 12° tilt means the ceramic element inside the housing is permanently tilted by 12°. This tilt is designed to compensate for the deadrise angle of your boat’s hull, ensuring the sonar beam is directed straight down for improved detection.

Choose a location inside the boat with at least 178 mm (7 inches) of free space for the housing height, installation of the spacer, and tightening of the nut and adjustment screws.
