XSONIC Airmar B175L (12°)

The XSONIC Airmar B175L (12°) is a CHIRP low-frequency 1 kW through-hull transducer designed for depth detection and water temperature measurement. It is specifically suited for fiberglass or wooden hulls and features an internal 12° tilted ceramic element to compensate for hull angle.

This transducer uses CHIRP low-frequency technology, operating in the 40 to 60 kHz range with a 20 kHz bandwidth. It also features Tilted Element™ technology, where the ceramic element is internally tilted by 12° to direct the sonar beam straight to the seabed, optimizing reading accuracy.

The XSONIC Airmar B175L (12°) operates over a CHIRP low-frequency range of 40 to 60 kHz. Its total bandwidth is 20 kHz.

The beam width of the XSONIC Airmar B175L transducer (12°) ranges from 32° to 21°, providing good coverage under the boat.

Yes, the XSONIC Airmar B175L (12°) transducer is equipped with a fast-response depth and water temperature sensor.

The XSONIC Airmar B175L (12°) transducer comes with a 10-metre (33-foot) cable.

The bronze housing of the B175L transducer (12°) is recommended for fiberglass or wooden hulls. It must never be installed in an aluminum hull to avoid electrolytic corrosion.

For installing the B175L (12°) transducer in a fiberglass or wooden hull, a mounting hole with a diameter of 95 mm (3-3/4 inches) is required.

The 12° internal tilt angle of the B175L transducer (12°) is designed to compensate for deadrise angles of hulls ranging from 8° to 15°. This ensures the sonar beam is directed straight toward the seabed, maximizing reading accuracy without requiring fairing.

For optimal performance, the transducer must be installed in an area where water flow under the hull is smooth, with minimal bubbles and turbulence. It must remain continuously submerged in water, and its beam must not be obstructed by the keel or propeller shafts. Avoid areas near water intakes or discharges, or behind hull planks and other irregularities.

Yes, CHIRP transducers generate more heat. It is crucial not to install the B175L (12°) in the engine compartment or any other hot location to prevent overheating and transducer failure. Additionally, it must always be used in water, as operating it in air can also cause overheating.

The arrow on top of the transducer must point toward the keel or the boat's centerline. This alignment ensures the internal transducer element matches the hull angle, guaranteeing sonar accuracy.

Applying antifouling paint is not mandatory, but it is recommended, especially in saltwater, to prevent marine growth that can affect sonar performance. Airmar certifies that applying Foulfree coating does not result in any loss of transducer performance.

The bronze housing of the B175L transducer (12°) is compatible with fiberglass and wooden hulls. It must not be used with aluminum hulls due to the risk of electrolytic corrosion.

The XSONIC Airmar B175L (12°) transducer is ideal for vessels up to approximately 11 meters (36 feet) in length.

The XSONIC Airmar B175L (12°) transducer is equipped with a 9-pin connector.

No, it is critical never to install a metallic transducer such as the B175L (12°) on a vessel with a positive-ground electrical system, as this could cause corrosion issues.

Yes, the XSONIC Airmar B175L (12°) transducer can be used with all types of propulsion.
