Product Description and Technical Data

Product information "AIRMAR B122 Smart Multisensor Thru‑hull, depth & temperature"

The B122 is a long-stemmed transducer designed for use in thick-hulled, wooden boats or vessels with a steep deadrise. The included high-performance fairing vertically orients the beam for strong return echoes, resulting in optimal performance even at higher speeds. And being a retractable design, the insert can be removed for servicing or storage.

Airmars Smart™ Sensors have embedded microelectronics-the transducer element and signal processor are only millimeters apart. The signals from the depth transducer and temperature sensor are processed right inside the housing itself. All that is needed to receive depth and temperature data is a single cable into a compatible network or display.

NOTE: The B122 is also available in an analog version.
