DESCRIPTION

 

The B923 is a standard power (2W CSTDMA) 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.

The B923 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 the unique FLEXI-FIT® bracket system, safe and secure installation is simple.
