Take a "big sweep" of your surroundings
The Garmin GMR 406 "big sweep" Open Array Radar Antenna allows you to scan more of what's out there with you while you're on the water. Whether ships, shores, birds or weather, you'll see it sooner with the GMR 406.

Compatible with Garmin 3000, 4000, 5000, 400 and 500 series multifunction displays.

Features:

• See Everything in Sharper Detail
  The GMR 406 is a 6-foot scanner with 1.1 ° beamwidth. With this bandwidth and 4 kilowatts of power, this radar offers outstanding clarity, precision and even more detailed 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, the GMR 406 radar image can be overlaid on the Garmin network's moving map cartography display. The on-screen display can also be split, allowing for a simultaneous view of mapping alongside the standard radar picture.
  
• Easily Connect to Garmin Marine Network
  The GMR 406 communicates with the Garmin Marine Network through a waterproof 100-megabit plug-and-play proprietary network — which gives you the ability to expand your boat’s system as needed. You can connect a GPS antenna and one remote network sensor (like the GMR 406) 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.
