Garmin GMR 18 HD+
PART NUMBER: 010-01719-00
The compact 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. GMR 18 HD+ features 8-bit true color 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 start using.
