Built-in AIS - Stay aware on the water with built-in AIS transmit and receive capabilities. This feature shows range course speed and the crossing situation of other AIS-equipped vessels around you to help you navigate.

Sleek Design - The compact and modern design features edge-to-edge glass and takes up minimal space at the helm.

Clear and Simple Communication - Eliminate unnecessary radio noise with automated squelch. If you miss a radio message you can replay it with VHF audio playback. When you need to maintain watch on multiple channels advanced watch modes make it easy.

Stay Connected - Quickly transmit a distress signal to nearby vessels with the distress button which uses Class D DSC to automatically send crucial information that can help emergency responders. You can also use the intuitive DSC features to quickly initiate contact with other AIS-equipped vessels - simply select the vessel on the AIS plotter view and call them with a tap of a button.

Easy to Update - Configure the radio program the MMSI number and get over-the-air software updates with the ActiveCaptain smartphone app via built-in Wi-Fi connectivity.

Installation is a Breeze - Installation is simple since VHF/DSC/AIS features only require a single VHF antenna and the GPS antenna/receiver is built into the unit. Chartplotter integration is seamless via the NMEA 2000 network and Garmin BlueNet Network.

Advanced Software Features

Adaptive Noise Cancellation - Advanced noise cancellation uses machine learning algorithms to eliminate wind wave and engine noise for our cleanest audio experience.

Automated Squelch - Radio activity is constantly monitored to eliminate unnecessary noise and static. You also have the option for manual fine-tuning.

Advanced Watch Modes - All VHF channels are continuously scanned for activity in the background allowing you to maintain watch over channel 16 and all your favourite preset channels simultaneously.

VHF Audio Playback - Didn’t catch that message? Replay it with VHF audio playback and listen to audio messages for up to 3 minutes on any channel.

External Speaker Support - Connect a compatible external speaker for more playback options beyond the built-in speaker on the fist mic.
