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. Airmar's 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. Features Depth and temperature 100 W 235 kHz frequency prevents mutual interference with other echo sounders on the vessel For thick-hulled or steep-deadrise vessel Can install as a low-profile mount with adapter ring Retractable insert in a bronze housing only Available in NMEA 0183 or NMEA 2000® standard Specifications Weight: 3.9 kg (8.7 lb.)
