This VHF marine radio is designed to save precious real estate on your helm. In addition to its great space-saving construction, it offers multi-station support and options including full Class D digital selective calling (DSC) with NMEA 2000 and NMEA 0183 capability, 25 watts of transmit power, NOAA weather alerts, two-way hailer, and position tracking. Users can record a 15-second message and send it to another DSC capable radio, and boaters can replay up to 90 seconds of the last incoming voice transmission with one simple button. Mount these radios anywhere on your boat, and easily operate them via the GHS 10 full-function remote microphone. With multiple stations, the system can even be used as an onboard boat intercom. Built-in AIS receiver turns this radio into a primary tool that helps mariners locate and identify other vessels. The international 300i AIS model offers ATIS support and private channel customization.
