Garmin GMR 18 XHD3 Dome Radar

High-Definition Magnetron Radar with Dual Range Mode!

The 18xhd3 is a powerful 18” radar dome loaded with advanced features typically found in open arrays. With superior traffic, obstacle and weather detection, the 18xHD3 give you peace of mind traveling during the dead of the night or even in heavy fog. It offers 4kw power output with a 48 nautical max range allowing you to stay on top of an incoming storm. The radar has a quiet dome drive motor.

The scan averaging technology is a first for a magnetron radar. It filters out sea clutter and interference to enhance the detection and display of constant targets. Pulse expansion and angular target-size processing techniques optimize on-screen object shapes for better interpretation at all range scales. The 60 RPM rotation speed has a faster screen refresh rate making this radar great when traveling at high speeds and also detects boats coming towards you sooner. The 18xhd3 automatically adjust levels to optimum settings for harbors, near shore and offshore in open waters taking the guess work out of your settings for the specific location. The Dual range overlay provides a split screen with side-by-side images on your compatible chartplotter. You can independently control the range settings for both close and long range.

You’re able to overlay the radar image on your compatible chartplotter and you can track up to 30 targets to help avoid collisions with MARPA target tracking (with appropriate sensors, sold separately). Variable range markers and electronic bearing lines allow rapid measurements of distance and bearing to vessels and land. The radar has a guard zone feature allowing you to receive an alarm when an object enters the zone. Locate flocks of birds at the water’s surface with the auto bird gain feature. The 18xhd3 radar is a great addition to your Garmin network.

The GMR 18 xHD3 magnetron radar provides a 48nm range max with dual-range mode and 5.2-degree beam width. Rotation speeds up to 60 rpm provide faster target updates, while true echo trails provide a historic trail of boats on your display. The 18xHD3 is a robust radar option that provides clarity and performance on the water!
