The B951 AIS Class B Transceiver is the perfect AIS for your sailing boat. Its enhanced transmit power and priority (5W SOTDMA) ensures maximum range in all conditions.
The easy-fit bracket enables quick installation without the use of screws. Inside the B951 is a high performance internal GPS antenna which means that it will GPS lock through fibreglass or a thin deck so an external GPS antenna is not always needed.
With dual NMEA 2000 and NMEA 0183 data outputs the B951 will seamlessly connect to any chart plotter and MFD.
This is all achieved within a single transceiver that is ruggedized and impervious to the effects of damp, temperature, water, shock and vibration providing many years of reliable operation.
