COMPACT, HIGH-DEFINITION RADAR DOME

This 18-inch high-definition radar dome pairs ease of use with advanced features typically found on open arrays for enhanced situational awareness.

If your boat has limited space for radar placement, this compact dome is for you.

It packs the power and echo definition you need, at all ranges.

When weather and sea conditions shift, the gain and sea filter do too — automatically.

See what’s close and far away with dual-range operation.

Know what’s out there.

COMPACT AND POWERFUL

This 18-inch dome radar delivers 4-kW transmit power and clear echo definition at all ranges. It has a maximum range of 48 nautical miles (88 km) and 48- or 24-RPM rotation speeds for fast screen refreshes.

HIGH-RESOLUTION RADAR

GMR™ 18 xHD features 8-bit true colour high resolution for outstanding target separation with less screen clutter on your chartplotter.

INTUITIVE OPERATION

This radar doesn’t have any complex user settings to deal with, so it’s easy to install and start using.

Performance in all conditions.

DYNAMIC AUTO GAIN

Gain levels automatically adjust to optimum settings for harbours, near shore and offshore in open waters.

DYNAMIC SEA FILTER

Gain automatically adjusts sea clutter for calm, medium and rough sea conditions.

DUAL-RANGE OPERATION

This feature enables the fully independent split-screen display of far and close radar views.

NO TRANSMIT ZONE

You have the option to protect areas behind the radar from being radiated while providing full forward-looking radar capability. This also makes installation more flexible.

RADAR OVERLAY

Overlay radar images onto your chartplotter’s map page. You can add an optional autopilot or heading sensor (sold separately) for best results.

MARPA TARGET TRACKING

GMR™ 18 xHD provides MARPA target tracking when combined with a multifunction display and heading sensor (sold separately).
