DESCRIPTION
 
The B952 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.

The B952 combines WiFi & Bluetooth for seamless wireless connectivity and AIS data streaming to any mobile device or PC. Your transceiver comes with CONNECT-AIS - your programming, configuration and transceiver health monitoring app which can be easily downloaded from either the iOS Apple Store or Google Play. With built in intelligent connectivity, integrated next generation GPS receiver & antenna and a unique FLEXI-FIT™ bracket system, safe and secure installation is simple.
