The em-trak B921 class B AIS transponder has standard 2W transmission power (CSTDMA) and is an improved replacement for the B100, the most widely used AIS transponder in the world.
The B921 is small and light, yet delivers the very best in class AIS receive and transmit performance, so you can see more AIS information and target at maximum range - all achieved with the lowest power consumption.

With built-in intelligent connection, integrated 2nd generation GPS receiver and antenna and unique FLEXI-FIT™ mounting system, installation is safe and simple.
