B200 Class B5W/SO

em-trak B200 is a high transmit power (5W) priority AIS Class B that is ideal for serious ocean sailors.

The high powered AIS engine delivers complete reliability and the very best AIS performance in terms of range and capacity. An internal battery is constantly maintained fully charged and ensures continuous operation for up 120 hours in the event of vessel power loss. Silent mode, where transmissions are switched off, but receiving continues, is easily enabled through the integrated switch or via your mobile phone using our CONNECT-AIS app.

Completely water and weather proof (IPx6 & IPx7 certified) and ruggedized to withstand shock and vibration the B200 will operate reliably for years in even the most extreme marine environments. Finally the dual NMEA2000 & 0183, coupled with serial ports, USB, WiFi, and Bluetooth make connecting to all your tablets, PC’s, display and navigation devices plug & play.
