Garmin’s next-generation, 4 kW high-definition GMR 18 xHD dome radar pairs ease of use with advanced open-array features. Its intuitive operation makes modes and settings simple to understand so you can enjoy great performance without a lot of technical know-how.

  • 4 kW high-definition 18" dome radar
  • Step up to xHD performance in a radome
  • Dynamic new shape for improved look and antenna performance
  • No complex user settings, easy to install and start using
  • New Dynamic Auto Gain and Dynamic Sea Filter continually adjust to your surroundings to provide optimal performance in varying conditions

The GMR 18 xHD delivers higher resolution than Garmin’s previous generation 18" dome radars. New Dynamic Auto Gain and Dynamic Sea Filter continually adjust to your surroundings, providing optimal performance in varying conditions. Choose from multiple levels of aggressiveness or use manual gain adjustment. Dual range operation allows fully independent split-screen display of far and close radar views in full 8-bit color (select chartplotters); range of 48 nm. "No Transmit Zone" protects areas behind the radar from being radiated while providing full forward-looking radar capability. This makes installation more flexible by providing more suitable installation options on your boat.

    Upgrade from the base model; immediate advantages are more distance and clearer near-in radar images. The most beneficial aspect of this transaction was the salesperson and his experience and expertise...highly recommend Ron in San Diego.
