The Garmin GMR404 open array radar antenna

The GMR404 is a 4-foot scanner with 1.8° beamwidth and a 72 nautical mile range. With this bandwidth and 4 kilowatts of power, this radar offers outstanding clarity, precision and target definition.

The GMR 406 is a 6-foot scanner with 1.1º beamwidth. With this bandwidth and 4 kilowatts of power, this radar offers outstanding clarity, precision and even more detailed target definition.

The GMR 18 allows you to experience the power of X-band digital marine radar scanning like never before. Get Powerful performance in a small container. At 18 inches, the 4 kW GMR 18 is twice as powerful as most other radars in its size and price range. Combine that with the antenna’s 5.2° beamwidth, and you’re looking at the best weather penetration and target definition in its class. Connect to Garmin Marine Network. GMR 18 has self-contained signal processing that provides the ideal “plug-and-play” addition to your Garmin Marine Network™.  Any compatible Garmin network chartplotter can double as your radar screen. And to aid in hazard avoidance, MARPA target tracking is supported (with optional heading sensor).

Sharpen your radar picture with high definition. The GMR 18 / 24 HD radar scanners offers a whole new level of radar performance, safety and situational awareness. Both scanners features high-powered Digital Signal Processing, providing sharper radar imagery and improved target separation to recreational boaters, professional mariners and yachtsmen. With automatic pulse optimization technology, the radar matches pulse widths and repetition rates with the nautical mile range that is selected. This gives you powerful 4-kilowatt radar penetration and unbelievably clear echo definition at all ranges.
