True Heading has received type approval for its Graphene Class B AIS transponders, which are now available for shipping throughout North America.

Four versions are available: CTRX Graphene, WiFi-AIS CTRX Graphene, CTRX Graphene+ and WiFi-AIS CTRX Graphene+. Each sends a yacht’s information—including heading, speed, vessel name and more—to AIS receivers aboard other vessels in the area. The data can be graphically displayed on electronic charts for collision avoidance and helps search-and-rescue teams respond faster in an emergency.

Each system plays nicely with NMEA 0183 and NMEA 2000 connectors, and comes with a voltage-protected USB for output to computers and chart plotters. The units with Wi-Fi work with mobile devices, and the Graphene+ models have a built-in VHF splitter. (No other Class B AIS on the market, according to True Heading, offers both Wi-Fi and a VHF splitter.)

“Our Graphene Class B AIS transponders have been extremely well received in Europe, and we are proud to make them available for recreational and commercial vessels in North America,” True Heading CEO Jens Johansson stated in a press release.
