Em-trak Class B AIS Transceiver B360 with Wi-Fi

Em-trak Class B AIS transceiver : B360

The AIS Class B B360 is a small robust, fully integrated IP67 ruggedized (weather and waterproof), 5W SOTDMA Class B with WiFi and integrated GPS antenna.

The em-trak B360 Class B AIS transceiver has been certified to IP67 standards meaning it is suitable for mounting externally.  The built in GPS antenna is handy as it reduces install time and does not require the installation of another GPS antenna.  The Em-trak B350 does still include the ability to add an external GPS antenna if desired or required. 

It's 5W transmit power provides increased range and reporting frequency, ideal for offshore sailors or those sailing in busy transmit areas.  Standard Class B AIS transceivers only transmit at 2W meaning less range.  These units also transmit using the SOTDMA method, like Class A commercial units, this means a faster update frequency than class B units and ensures you are always seen! The unit is even compatible with satellite AIS systems.

The B350 Em-trak AIS transceiver includes both NMEA0183 and NMEA2000 interfaces so it is ready and able to be connected to all chartplotters.  The B350 includes stealth (silent) mode functionality also, allowing it to continually receive AIS messages, but not transmit.  We have a dash mounted AIS silent mode switch available as an accessory item.

The WiFi feature adds the ability for devices such as iPads or other mobile devices to connect wirelessly to the B360 and receive AIS, GPS and multiplexed NMEA data for use in mobile apps such as iNavX, iSailor and more.
