Communicate with Confidence

The VHF 300 AIS is equipped with a two-way 30-watt hailer system for communication with other boats or deckhands. In addition, the VHF 300 AIS has a patent-pending voicemail feature that lets you pre-record a 15-second message and deliver the message to any Digital Selective Calling radio. You’ll also have the ability to replay the last 90 seconds of any incoming voice transmission at the touch of a button.

Identify Your Surroundings

With the VHF 300 AIS, you’ll get detailed data on your surroundings regardless of visibility. You’ll have ship identification information, position, course, and speed for vessels equipped with AIS within range. The VHF 300 AIS also receives both Class A and Class B signals at the same time to ensure no critical information is lost.

Take Full Control

The VHF 300 AIS is operated via the GHS 10 handset microphone that allows full radio control from a remote location. The GHS 10 features a crisp 2-inch LCD display, dedicated rotary key for frequent tasks, and three soft buttons for dynamic controls. The VHF 300 AIS uses the supplied four-inch active speaker with volume knob, the built-in speaker on the GHS 10 or an optional third-party passive speaker.

Save Space

With a space-saving black box configuration, you’ll be able to mount the VHF 300 AIS wherever you choose. And with multi-station support, you can add the wired GHS 10 handset microphones throughout your vessel without having to add existing receivers. The system can also be used as an on-boat intercom if you have multiple stations aboard your vessel.

Stay Safe on the Seas

The Garmin VHF 300 AIS provides full NOAA weather alerts and Class D Digital Selective Calling (DSC) capability via NMEA 0183 or NMEA 2000 connectivity. Should trouble arise, DSC provides distress calls with the push of a button. And if your boat is already interfaced with a compatible GPS chartplotter, you’ll get mayday signaling and a digital broadcast of your boat’s position. The VHF 300 AIS also features Position Tracking, which allows a mariner to locate and keep tabs on up to three other boats in the area.
