WatchMate XB-6000 is a Class B High Performance AIS transponder from Vesper, with NMEA 2000 Gateway and an external GPS antenna.


The high-performance Class B AIS with built-in NMEA 2000 gateway and internal GPS, XB-6000 integrates AIS, GPS and NMEA information so that you can see your safety and navigation on any AIS-capable chart plotter or MFD. Or use your PC and Mac for easy computer navigation. Easily integrate AIS to your existing marine electronics and convert NMEA 2000 & 0183 instrument data to USB, facilitating 3rd party navigation software.


  • NMEA 2000 / 0183 and waterproof USB
  • Compatible with all NMEA 2000 certified chart plotters and MFD’s
  • The only AIS transponder that can be used as a GPS source for NMEA 2000
  • Fast 5Hz GPS update rate provides greater detail and higher resolution plotting
  • Can be put in Silent Mode (receive-only)
  • Includes 50 channel GPS with WAAS/EGNOS and powerful external GPS antenna
  • Built-in internal GPS antenna allows for easy installation when the XB-6000 has a view of the sky. Perfect for small vessels
  • Galvanic isolated USB and NMEA ports protects the transponder and your other equipment against damage and installation problems


The XB-6000 translates NMEA 2000 instrument data such as heading, wind, depth, speed, log, and temperature. This allows you to view this data, along with GPS and AIS information, simultaneously on all AIS-capable chart plotters, multi-function displays and computer software. Works seamlessly with Garmin, Raymarine, Simrad, B&G, Lowrance and others. The built-in internal GPS antenna means there is no need for multiple external GPS antennas in many installations. You can even use the XB-6000 as your primary GPS source for all chart plotters and multi-function displays.
