The B954 is most feature-rich high transmit power (5W SOTDMA) AIS transceiver in the B900 range. The B954 combines WiFi & Bluetooth for seamless wireless connectivity and AIS data streaming to any mobile device, PC or wearable, with an integrated VHF antenna splitter to enable your transceiver to share your existing VHF antenna without any loss of performance. Like all B900 transceivers, it also includes an integrated next-generation GPS receiver and antenna and is designed for em-trak's unique FLEXI-FIT® bracket system to make installation as easy as possible.

Light-weight and completely weatherproof, the B954 delivers the very best AIS receive and transmit performance with increased range and transmission priority. Your transceiver will also work with our CONNECT-AIS mobile phone app to make programming, configuration and transceiver health monitoring simple and convenient.
