The em-trak B921 Class B AIS Transceiver is a compact, durable 2W CSTDMA transceiver engineered for reliable vessel tracking and situational awareness. It features an internal high-performance GPS receiver (internal antenna provided; external antenna optional), dual receivers and one transmitter with -111 dBm receiver sensitivity, enhanced RF screening and built-in surge protection. The B921 supports NMEA 0183 and NMEA 2000 data interfaces, consumes ultra-low power (average current 135mA at 12V), and is IPx6/IPx7 rated for water and pressure spray protection. Installation is simplified with the FLEXI-FIT bracket system.
