em-trak B951 Class B SOTDMA 5W AIS Transceiver - 430-0009
em-trak B951 Class B AIS Transceiver - 430-0009
The B951 is a high transmit power (5W SOTDMA) AIS Class B transceiver that is small, light-weight, yet delivers the very best AIS receive and transmit performance so you see more AIS information and targets at maximum range – all achieved with the least power consumption.
With built-in intelligent connectivity, integrated next-generation GPS and the unique FLEXI-FIT® bracket system, safe and secure installation could not be easier.

The B950 series AIS transceivers feature a built-in GPS antenna. In most cases this will work fine as long as the unit is mounted upright and not directly below metalwork or cables. If your installation is either compromised by metalwork or cables, or your hull is built from metal, then the GPS100 remote antenna is recommended.
