The Garmin AIS 800 is a compact blackbox Class B/SO transceiver that simultaneously broadcasts your vessel's position to nearby AIS-equipped boats and receives their target data — giving you a clearer, more complete picture of traffic around you. With 5 watts of transmit power, an internal VHF antenna splitter, and built-in GPS, it integrates cleanly into existing onboard systems without demanding extra antenna runs or display hardware.

Note: FCC regulations require all units sold in the US to be programmed by a qualified technician. A copy of your MMSI Registration or FCC Ship Station License, along with the vessel master or owner's signature on the completed programming form, is required at time of purchase.
