Airmar B164 - Bronze Through-Hull 1kW (50/200kHz) Tilted Element (20°) + Temperature – (8-pin)

The Airmar B164 transducer operates on two frequencies: 50 kHz and 200 kHz. This duality provides versatility for deep-water detection and target discrimination.

The Airmar B164 transducer features a 20° tilted element. This Tilted Element™ technology compensates for your boat's deadrise angle to ensure a vertical sonar beam without requiring an external fairing block.

Yes, the Airmar B164 transducer is equipped with a fast-response temperature sensor.

The bronze housing of the Airmar B164 transducer is specifically recommended for fiberglass or wooden hulls. Never install a bronze housing on an aluminum hull, as this would cause electrolytic corrosion.

The Airmar B164 transducer can detect depths up to 549 meters at 50 kHz and up to 244 meters at 200 kHz.

The beam width of the Airmar B164 transducer is 22° at 50 kHz and 6° at 200 kHz (measured at -3 dB).

The Airmar B164 transducer has a low-profile design that protrudes less than 6.35 mm below the hull. This reduces drag and eases trailer rollover clearance, making it ideal for fast sportfishing boats.

The Airmar B164 transducer is supplied with a 10.4 m (34 ft) cable.

The Airmar B164 transducer is equipped with an 8-pin Garmin connector, ensuring direct compatibility with Garmin devices.

The Airmar B164 transducer, with its 20° tilted element, is designed to compensate for deadrise angles ranging from 16° to 24°. It is critical to ensure the transducer’s tilt angle matches the deadrise angle of your hull at the chosen mounting location.

For installation of the Airmar B164 transducer on a fiberglass or wooden hull, a 95 mm (3-3/4 inch) diameter hole must be drilled.

Yes, marine sealant is mandatory. It must be applied to the threads of both adjustment screws to firmly hold the hull nut in place. Additionally, it is recommended to apply marine sealant over the entire inner surface of the spacer to fill the gap and prevent vibrations.

During installation, the arrow on the top of the transducer must point toward the keel or the central axis of the boat. This ensures the internal element angle of the transducer aligns with the hull deadrise angle.

Yes. The Airmar B164’s low-profile design (less than 6.35 mm below the hull) and its ability to compensate for deadrise angles make it ideal for fast sportfishing boats up to 11 m, including trailerable models.

Yes, antifouling paint such as Foulfree® can be applied. Airmar certifies that applying Foulfree to its depth sounders does not result in any performance loss. This non-toxic and durable coating prevents marine growth from adhering to the depth sounder’s surface, ensuring optimal performance.

The main difference lies in the housing material: the B164 has a bronze housing and is intended for fiberglass or wooden hulls. The SS164 has a stainless steel housing and is compatible with all hull materials, including metal hulls (with appropriate isolation).

No, the Airmar B164 is a traditional dual-frequency transducer (50/200 kHz). While the installation manual mentions CHIRP models, the B164 itself is not a CHIRP model.

Yes, it is imperative never to use solvents. Cleaners, fuels, sealants, paints, and other products may contain solvents that can damage plastic parts, particularly the face of the depth sounder.
