The Garmin VHF 300i marine receiver combines radio communication and 1 or 25 watts of transmit power with multi-station support to give you the flexibility and convenience you need to safely navigate and communicate on the open waters. The VHF 300i comes standard with a two-way hailer system and is also NMEA 0183 and NMEA 2000 compliant to offer greater onboard functionality.

Communicate with Confidence

The VHF 300i is equipped with a two-way 30-watt hailer system for communication with other boats or deckhands. In addition, the VHF 300i 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.

Take Full Control

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

With a space-saving black box configuration, you’ll be able to mount the VHF 300i wherever you choose. And with multi-station support, you can add the wired GHS 10i 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.

The Garmin VHF 300i provides 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 300i also features Position Tracking, which allows a mariner to locate and keep tabs on up to three other boats in the area.
