The EM-Trak AIS Class B Tranceiver - GNSS Receiver, NMEA 2000, NMEA 0183, Wi-Fi, Bluetooth, Integrated VHF Splitter is a standard transmit 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 B924 combines Wi-Fi & Bluetooth for seamless wireless connectivity and AIS data streaming to any mobile device or PC, as well as 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 and antenna and a unique FLEXI-FIT bracket system, safe and secure installation is simple.
Core technology continuously developed and proven over many years guarantees you the very best AIS receive and transmit and GPS performance, coupled with the lowest power consumption of any comparable AIS transceiver. Quality engineered and manufactured with the best components to provide years of continuous, maintenance free operation in even the most extreme environments impervious and protected against the long-term effects of water, damp, shock, vibration and extreme cold and heat.
Guaranteed connectivity to any chart-plotter and PC/Phone/Tablet/Watch and navigation app. This ensures you are not limited to any display device or navigation application now or in the future and can maximize AIS related functionality such as weather, MOB, anti-collision, anchor safety, vessel tracking and more.
em-trak transceivers are rigorously tested and certified for global regulatory compliance. This includes FCC, USCG, Canada and EU test and certification. em-trak transceivers are designed and engineered for a lifetime of reliable operation in even the most extreme environments. This is supported by our best in class global warranty program with 24/7 customer support.
