The Garmin AIS800 is a Class B blackbox transceiver built for boaters who want to both see and be seen on the water. It receives target data from other vessels in your area and transmits your own position, course, and identity back out, giving you two-way traffic awareness instead of receive-only coverage. The small black box enclosure tucks behind a helm or in a console, then feeds data to a compatible chartplotter or multifunction display. For cruisers, commercial operators, and anyone running congested or low-visibility waters, it adds a real layer of collision avoidance.

Garmin rates this unit at 5 watts of transmit power using the Class B Self-Organizing Time Division Multiple Access protocol, with the ability to drop to 1 watt when remotely switched by authorities per international regulations. A built-in receiver handles position fixing, and a connector supports an optional external antenna for difficult installs. The internal splitter lets the marine radio and the transceiver share a single antenna, which cuts down on hardware and through-deck penetrations. Connectivity runs over both the 2000 and 0183 marine data standards, so it ties into most modern helm electronics. Power input accepts 12 to 24 Vdc at 2 A max, the enclosure carries an IPX7 water rating, and the antenna connection uses a 50 ohm SO-239 fitting. Compass-safe distance is 40 cm.
Run this transceiver on a coastal cruiser, a sportfisher working busy inlets, or a sailboat crossing shipping lanes where knowing the heading of a nearby freighter matters. Because it shares a single antenna through the internal splitter, it pairs cleanly with an existing radio rather than forcing a second mast antenna. The blackbox form factor means it disappears into the install while your existing screen does the display work. Pair it with a compatible plotter from our chartplotter selection, and check our network sensors and cabling to wire it into your helm.
It does both. The AIS800 receives target data from other vessels in your area and transmits your own position, course, and vessel identity using the Class B SOTDMA protocol at 5 watts. That two-way capability is what separates it from receive-only units that show traffic but never broadcast your own position.
No. The AIS800 includes an internal splitter that lets the marine radio and the transceiver share a single antenna. That reduces hardware and limits the number of through-deck penetrations on the install.
It connects over both the 2000 and 0183 marine data standards, so it integrates with most current Garmin chartplotters and multifunction displays, along with many compatible third-party helm units. The blackbox unit has no screen of its own and relies on a connected display for output.
Yes. The unit includes an internal receiver for position fixing and provides a connector for an optional external antenna when the mounting location makes internal reception difficult. The 50 ohm SO-239 connector handles the antenna connection.
It accepts 12 to 24 Vdc with a 2 A maximum draw. At 12 Vdc it pulls less than 400 mA, and at 24 Vdc less than 250 mA. Garmin specifies a 5 A, 125 V fast-acting fuse for the install.
