EM-TRAK Class B High Power AIS with Transceiver & Bluetooth

The em-trak B952 is a high-power Class B AIS transceiver (5W SOTDMA). It's small, lightweight and uses very little power.

Built-in Wi-Fi and Bluetooth stream AIS data to any phone, tablet, PC or wearable, so everyone on board can see it. Up to nine devices can connect at the same time.

Em-Trak's CONNECT-AIS app makes setup, configuration and monitoring easy. The B952 processes data in real time, with increased range and transmission priority. It comes in a compact, rugged package that's easy to install and built to run without maintenance in the harshest marine conditions.
