XSONIC Airmar B175L (20°)

The NAVICO XSONIC Airmar B175L (20°) transducer is a CHIRP through-hull 1 kW transducer designed for deep-sea fishing. It provides depth and water temperature data, operating on a CHIRP low-frequency range of 40 to 60 kHz with a total bandwidth of 20 kHz.

The XSONIC Airmar B175L (20°) transducer has a detection range up to 762 meters (2500 feet), and potentially 3000 feet under optimal conditions.

This transducer operates over a low-frequency CHIRP range of 40 to 60 kHz, providing a total bandwidth of 20 kHz.

Yes, the XSONIC Airmar B175L (20°) transducer is equipped with a fast-response water temperature sensor in addition to its depth function.

The XSONIC Airmar B175L (20°) transducer has a transmit power of 1 kW.

The transducer incorporates a fixed 20° tilted ceramic element. This tilted element technology compensates for the boat’s deadrise angle to direct the sonar beam straight to the bottom.

The B175L transducer has a low profile, protruding only 6 mm from the hull, making it suitable for trailer-transported boats.

Yes, the transducer is supplied with a 10 m (33 ft) cable and a 9-pin connector.

The bronze housing of the B175L transducer is specifically recommended for fiberglass or wooden hulls.

No, it is critical to never install a bronze housing on an aluminum hull, as this would cause electrolytic corrosion.

Installing the B175L transducer requires a 95 mm (3-3/4 inch) hole in the hull.

For optimal performance, choose a location where water flows smoothly under the hull, with minimal bubbles and turbulence, and where the transducer remains continuously submerged. Avoid areas near water intakes or discharges, seams, or hull irregularities. The beam must not be obstructed by the keel or propeller shafts.

The B175L transducer has a fixed tilt angle of 20°. It is designed to compensate for deadrise angles ranging from 16° to 24°, ensuring the sonar beam is directed straight to the bottom for optimal echo returns.

It is important not to install the CHIRP transducer in the engine compartment or any other hot location, as it could overheat and fail. Ensure the transducer is always operated in water, since running it in air can cause overheating and failure.

Applying water-based antifouling paint is mandatory in saltwater to prevent marine growth. Airmar certifies that applying the Foulfree coating does not result in any loss of transducer performance.

This transducer is compatible with CHIRP sonar systems. It is an essential accessory compatible with Lowrance sonars.

Yes, thanks to its low profile that protrudes only 6 mm from the hull, the B175L transducer is perfectly suited to trailer-sailors.

Yes, the B175L transducer can be used with all types of propulsion.

The B175L transducer is recommended for boats up to 8 meters (25 feet). For hulls under 36 feet, its performance is comparable to a fairing installation.

No. Airmar certifies that applying the Foulfree coating to its transducers does not result in any loss of performance. The coating is also non-toxic and eco-friendly, designed to prevent marine growth from adhering to the transducer's surface.
