Garmin AIS™ 800 Blackbox Transceiver

Garmin AIS™ 800 Blackbox Transceiver Product Description

Enhance Your Boating Safety with Advanced AIS Technology

Navigating busy waterways or foggy conditions demands tools that keep you one step ahead. The Garmin AIS 800 blackbox transceiver steps up as a vital ally, broadcasting your boat's position, speed, and course to nearby vessels while pulling in their data for a complete picture of your surroundings. This Class B device punches above its weight with 5 watts of transmit power, ensuring your signal reaches farther—especially when you're cruising above 14 knots, where it ramps up reporting for quicker updates.

Unlike basic receivers, this transponder actively participates in the AIS network, making you visible to commercial ships and recreational boats alike. Pair it with your existing VHF setup via the internal antenna splitter, and you've got a streamlined system without extra hardware clutter. Its compact blackbox design slips easily into tight spaces, perfect for sailboats, fishing vessels, or weekend cruisers aiming to boost confidence on the water.

Key Features That Set It Apart

• Powerful 5W Transmission: Class B/SO protocol delivers rapid position reports, outperforming standard 2W units in range and speed—ideal for dynamic marine environments.
• Integrated GPS Receiver: Built-in positioning with an option for external antenna upgrade, ensuring precise data even in challenging signal areas.
• Seamless VHF Sharing: Internal splitter lets AIS and VHF radio use one antenna, simplifying installs and reducing cabling hassles.
• Plug-and-Play Connectivity: NMEA 2000 and 0183 support integrates effortlessly with Garmin chartplotters, multifunction displays, and other marine electronics.
• Rugged Build: IPX7 waterproof rating shrugs off splashes and submersion, thriving from chilly 5°F mornings to sweltering 131°F afternoons.

Real-World Benefits for Boaters

Imagine threading through shipping lanes at dusk: AIS icons pop up on your plotter, showing exact positions and headings of freighters long before you spot their lights. For coastal anglers or liveaboard adventurers, it means fewer close calls and more peace of mind. The 250-400mA draw fits low-power systems, and its 2 LEN NMEA 2000 footprint won't overload your backbone.

Boat owners praise its reliability in rough seas, where traditional radar might falter. By sharing your MMSI-registered details, you enable mutual awareness—crucial since larger vessels rely on AIS for traffic separation. Note for U.S. users: Federal rules require professional programming with your MMSI and vessel docs for compliance.

Frequently Asked Questions

What makes the Garmin AIS 800 different from a standard AIS receiver?

Unlike receivers that only listen, the AIS 800 is a full transceiver. It transmits your vessel's data to others while receiving theirs, enhancing two-way collision avoidance.

Does it require a separate GPS antenna?

No, it has a built-in GPS receiver. For better reception in obstructed areas, connect an optional external antenna.

Can it share an antenna with my VHF radio?

Yes, the internal VHF antenna splitter allows seamless sharing of a single antenna between AIS and VHF, saving space and cost.

Is this suitable for small recreational boats?

Absolutely. Its Class B certification, compact size, and low power draw make it perfect for yachts, fishing boats, and sailboats under 300 gross tons.

How does the 5W power improve performance?

It provides greater range and faster dynamic reporting (SO mode) at speeds over 14 knots, outperforming typical 2W Class B units in crowded or open waters.

What connectivity options does it support?

NMEA 2000 for plug-and-play with Garmin plotters and MFDs, plus NMEA 0183 compatibility for broader integration.

Is professional installation required?

DIY is feasible for handy boaters, but U.S. FCC rules mandate technician programming with your MMSI for legal transmission.

Equip your vessel with the Garmin AIS 800 and sail smarter, not harder. Its blend of power, simplicity, and integration turns potential hazards into manageable blips on your screen.
