Garmin GMR 404 Marine Radar

The GMR 404 open array radar allows you to scan more of what's out there while you're on the water. Whether ships, shores, birds or weather, you'll see it sooner with the powerful 4-foot GMR 404 and its larger counterpart, the GMR 406.

See Everything in Sharper Detail

The GMR 404 is a 4-foot open array scanner with 1.8 degree beamwidth and a range of 72 nautical miles. With this beamwidth and 4 kilowatts of power, the 404 offers outstanding clarity, precision and target definition. You can also use the 404 to avoid traffic on the water with MARPA target tracking.

Easily Connect to the Garmin Marine Network

The GMR 404 transmits data over the Garmin Marine Network , a 100-megabit plug-and-play proprietary network that gives you the ability to expand your boat's system as needed. Once connected to the network, any network-compatible Garmin chartplotter can double as your radar screen. And as an aid to locational awareness, you can overlay the GMR 41 radar image on the chartplotter's map page. You can also split the on-screen display so that you can view the map and the standard radar page simultaneously.
