B951 Class B AIS Transceiver - 5W SOTDMA
**As the FCC requires all units sold in the US to be programmed by a qualified technician. Please submit the form below for programming at the time of purchase. A copy of the MMSI registration or FCC Ship Station License is required along with the vessel master or owner's signature on the completed programming form.**
The B951 is a high-power (5W SOTDMA) Class B transceiver, delivering advanced performance and ultimate reliability through em-trak's next-gen technology. Small and durable, this trusted transceiver processes all AIS transmissions in real-time, with increased range and transmission priority so you always have the complete picture and the time to respond, even in the busiest waters.
em-trak's flexible, intelligent connectivity means the B951 can be paired to any chart-plotter and its next-gen GPS receiver and the antenna are already integrated inside the device to provide best-in-class, ultra-low power consumption, and performance. em-trak's unique FLEXI-FIT® bracket system completes the package and ensures easy installation.
