The B953 is a high transmit power (5W SOTDMA) AIS Class B transceiver that is small, and lightweight, 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.

The B953 has an integrated VHF antenna splitter which enables the transceiver to share your existing VHF antenna without any loss of performance. With built-in intelligent connectivity, integrated next-generation GPS receiver & antenna, and a unique FLEXI-FIT bracket system, safe and secure installation is simple.
