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 retractable design, the insert can be removed for servicing and storage. Airmar’s Smart™ Sensors have embedded microelectronics-the transducer element and signal processor are only millimeters apart. The signal from the depth transducer is processed right inside the sensor itself. All that is needed to receive depth and temperature data is a single cable into a compatible network or display.
