Airmar B122-235-N2 235kHz Thru-Hull Smart Sensor Long Stem

Fits: NMEA 2000 instruments

The long-stem, B122 transducer is designed for use in thick-hulled wooden boats or vessels with a steep deadrise. The included High-Performance Fairing vertically orients the sound beam for strong return echoes, resulting in optimal performance. The Smart™, digital, signal processing inside the housing sends depth and temperature data to a chart plotter, radar screen, or digital display eliminating the need for a dedicated depth sounder. And being retractable, the insert can be removed for servicing and storage.

Can be installed with Low-Profile adaptor ring 33-634-02 (sold separately) instead of fairing.
