The em-trak B951 Class B AIS transceiver is a high output power (5W SOTDMA) class B transceiver, with built-in GPS antenna.

The em-trak B951 Class B AIS transceiver has a built in GPS antenna which reduces install time and does not require the installation of another GPS antenna.  The Em-trak B951 does still include the ability to add an external GPS antenna if desired or required. 

The em-trak B951 includes a high power 5W transmitter which provides increased range and reporting frequency, ideal for offshore sailors or those sailing in busy 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 em-trak B951 AIS transceiver includes both NMEA0183 and NMEA2000 interfaces so it is ready and able to be connected to all chart plotters.  The em-trak B951 includes stealth (silent) mode functionality also, allowing it to continually receive AIS messages, but not transmit.
