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