Compact, Streamlined 4 kW Dome

The compact Garmin GMR 18 HD+ Dome Radar is a good
choice for boats with limited room for radar placement. It delivers
4 kW of transmit power and clear echo definition at all ranges to
enhance situational awareness. Overlay radar images onto your
chartplotter map page; however, for best overlay results, an
optional autopilot or heading sensor is recommended. It also helps
you avoid traffic on the water. GMR 18 HD+ provides MARPA target
tracking when combined with a multifunction display and heading
sensor (sold separately).

Dynamic Auto Gain automatically adjusts to your surroundings for
optimal performance in all conditions. Dynamic Sea Filter
automatically adjusts sea clutter, depending on sea conditions. The
GMR 18 HD+ features 8-bit true colour resolution for a clear
presentation on your chartplotter screen. It has a maximum range of
36 nautical miles with a minimum range of 20 meters and a rotation
speed of 24 RPM. There are no complex user settings, and it’s easy
to install and use.
