Garmin's AIS 300 receiver provides an affordable solution for receiving AIS target data, giving mariners improved situational awareness and better collision avoidance. This affordable NMEA 2000®-compatible AIS receiver alerts you to potential collisions with other AIS-equipped vessels in your vicinity. When used with a Garmin chartplotter and VHF, vessel information is quickly accessible, and a VHF DSC call to the threat can be made with minimal key presses.
Know Your Surroundings
This black box AIS receiver integrates with a Garmin chartplotter and VHF radio to enable automatic AIS target calling and display AIS target data directly on the chartplotter screen. To ensure there's no loss of information, dual-channel monitoring enables independent observation of both AIS channels. The AIS 300 receiver also includes Class A and Class B reception, which allows decoding of AIS traffic from commercial and leisure vessels. Additionally, the AIS 300 can further aid in collision avoidance by integrating a Closest Point of Approach (CPA) alarm when connected to a compatible chartplotter. Mariners can rest easy knowing they have visibility of all boat traffic around them.
Installation Made Easy
AIS 300 is NMEA 2000 certified and easily added to your existing NMEA 2000 network. It is compatible with both 12-volt and 24-volt boat systems. Additionally, the AIS 300 offers NMEA 0183 output with selectable speed. A built-in passive splitter enables one VHF antenna to serve both the AIS 300 and any VHF radio, making for easy installation. Once fitted, users can view all AIS data on their chartplotters for all the information they need at their fingertips.
