The Smart Alternative! Airmar’s B122 Smart™ Sensor features embedded micro-electronics. Depth and temperature signals are processed inside the sensor and can be displayed on any radar, chart plotter, or device that accepts NMEA 0183 or NMEA 2000® data. The 235 kHz frequency prevents mutual interference with other echosounders on the vessel. Thru-Hull Retractable, Long-Stem Stronger Echo Returns The B122 retractable, long-stem, bronze transducer is designed for use in thick hulled wooden boats or vessels with steep deadrise. The included high-performance fairing vertically orients the sound beam for stronger return echoes resulting in optimal sounder performance. The B122 can also be installed as a low-profile mount with an adaptor ring. • Long-stem, depth and temperature with a High-Performance Fairing Smart™ Sensor Features • Can install as a low-profile with adaptor ring • 235 kHz frequency prevents mutual interference with other echosounders on the vessel • For thick hulled or steep deadrise vessels • Retractable, Bronze housing only • Available in NMEA 0183 or NMEA 2000® versions • 6 m (20’) NMEA 2000 cable or 10 m (33’) NMEA 018
