100 W
The B122 has an extra-long housing 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.
