See more than before with this open array scanner The GMR 404 open array radar antenna 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 GMR 404 and its counterpart, the GMR 406. See Everything in Sharper Detail The GMR 404 is a 4-foot scanner with 1.8º beamwidth and a 72 nautical mile range. With this bandwidth and 4 kilowatts of power, this radar offers outstanding clarity, precision and target definition. Integrate with any network-compatible Garmin chartplotter Any network-compatible Garmin chartplotter can double as your radar screen. And as an aid to locational awareness, you can overlay the GMR 404 radar image on the Garmin network's moving map cartography display. You can also split the on-screen display so that you can view the map and the standard radar page simultaneously. Easily Connect to Garmin Marine Network The GMR 404 communicates with the Garmin Marine Network through a waterproof 100-megabit plug-and-play proprietary network which gives you the ability to expand your boats system as needed. You can connect a GPS antenna and one remote network sensor (like the GMR 404) directly to a multifunctional display. Or, with the addition of the GMS 10 Network Port Expander, you can connect multiple displays and network sensors to the same network.
