Garmin GMR 18 HD+. Extremely suitable for boats with limited space for a radar. For optimal use, we recommend using an autopilot or course sensor with this. You can also stay at a distance from other boat traffic. GMR 18 HD+ uses MARPA targets when combined with a multifunction display and course sensor (sold separately).
Dynamic Auto Gain automatically adjusts radar detection to ambient conditions for optimal results under all conditions. Dynamic Sea Filter automatically adjusts sea noise depending on sea conditions. GMR 18 HD+ has an 8-bit True Color color display, allowing data to be displayed clearly on the chartplotter's screen. Has a maximum range of 36 nautical miles and a minimum range of 20 meters and a rotation speed of 24 RPM. There are no complicated user settings: the unit is easy to install and quickly ready for use.
The new Dynamic Auto Gain and Dynamic Sea Filter continuously adjusts to your environment for optimal performance in changing conditions. Choose from several levels or use manual gain adjustments. Dual range allows you to split the screen and view radar images from near and far independently in 8-bit color (on certain chart plotters); range of 48 nautical miles. A “radar-free zone” prevents areas behind the radar from being scanned, but still provides full radar functionality. This makes installation more flexible because you can choose from multiple suitable installation options.
