Highlights for Garmin AIS 300 Automatic Identification System Receiver

The Garmin AIS 300 enables monitoring of other nearby AIS-equipped vessels that may pose a collision risk. When connected to a Garmin chartplotter and Garmin VHF radio by NMEA 2000, mariners can display AIS target data and initiate a call to a target directly from the chartplotter screen. Dual-channel monitoring allows for independent monitoring of both AIS channels to ensure no loss of information. The Garmin AIS 300 receiver also includes the Class A and Class B reception which allows decoding of AIS traffic from both commercial and leisure vessels. Additionally, the Garmin AIS 300 can aid in collision avoidance by integrating a Closest Point of Approach (CPA) alarm when connected to a compatible chartplotter.The Garmin AIS 300 is NMEA 2000 certified and is easily added to an existing NMEA 2000 network. It is compatible with both 12-volt and 24-volt boat systems. Additionally, the Garmin AIS 300 offers a NMEA 0183 output withs selectable speed. A built-in passive splitter enables one VHF antenna to serve both the Garmin AIS 300 and any VHF radio, making for easy installation. Once installed, users can view all AIS data on their chartplotters, so they'll have all the information they need at their fingertips. Mariners can rest easy knowing they have visibility of all the boat traffic around them.


  • Aids mariners in navigation and collision avoidance NMEA 2000 certified for easy installation
  • Built-in passive splitter will enable one VHF antenna to serve for both the Garmin AIS 300 and any VHF radio with minimal signal loss
  • Integrate AIS target data information directly on the chartplotter display (AIS target overlay, MMSI number saving, vessel status and more)
  • When integrated with a compatible Garmin chartplotter and VHF 200 or 300 series radio via NMEA 2000, mariners can initiate a call to any MMSI target.
  • Receives both Class A and Class B signals simultaneously and allows mariners to independently monitor both channels
