Garmin GMR 604 xHD



Combining high-end performance and high-definition digital imaging technology at a truly affordable price, the GMR 404 xHD radar brings new value and clarity to this segment of Garmins open array lineup.

Everything Looks Better in xHD

This 4 ft (1.22 m) scanner with a 4 kW radar transmitter uses the latest in high-definition digital signal processing to deliver a dramatically sharper and clearer radar picture - with improved range resolution, target separation and clutter removal on the display.

The advanced xHD electronics yield nearly 8 times more signal processing bandwidth than predecessor designs. So, you can count on improved resolution and target separation, plus better detection and presentation of small or distant returns that might go undetected on traditional analog radar systems.

When installed with Garmins GPSMAP 6000 or 7000 series network multifunction displays, the GMR 404 xHD also can display images in full color, using a multi-hued spectrum (in much the same way that your sonar fishfinder does) to indicate radar return strength or target density.

Thus, whether its birds, rocks, buoys, structures or other boat traffic on the water, youll see more of whats out there when you scan with the GMR 404 xHD.

Its maximum range is 72 nm, and the selectable 24/48 RPM rotation speeds let you adapt the scan to various sea, weather or situational conditions. Optional MARPA target tracking also is supported, when installed with a Garmin heading sensor.

Easy Network Integration

The GMR 404 xHD transmits data over the Garmin Marine Network, a high-speed, plug-and-play proprietary network that makes it easy to expand your boats system with the latest capabilities.

Since all radar signal processing is contained in the remote antenna/scanner, any network-compatible Garmin chartplotter can double as your radar screen.

In fact, you can overlay the GMR 404 xHD radar image on the chartplotters map page as an aid to situational awareness.

And Garmins handy Dual Range feature enables your compatible chartplotter/MFD to display 2 range scans at once, so you can view close and distant targets simultaneously.
