GMR Fantom™ 18x Radome, Black

The Garmin GMR Fantom™ 18x is a high-performance solid-state dome radar designed for boaters who require reliable long-range target detection, fast scanning, and exceptional clarity in all weather and light conditions. With an impressive 50 watts of output power, it delivers extended range performance and enhanced target definition, helping you track boats, land, markers, and weather up to 48 nautical miles away.

The faster rotation speed of up to 60 RPM provides rapid refresh rates for tracking moving targets and supports safe navigation when traveling at higher speeds. MotionScope™ technology uses Doppler processing to detect moving objects and highlight them in color, giving you a clear visual indicator of approaching vessels or severe weather cells to improve awareness and collision avoidance.

Energy management features help extend your time on the water. The power save mode lets you control power draw depending on your needs, while the timed transmit mode allows you to schedule active and sleep intervals down to the second—ideal for conserving battery power during trolling, anchoring, or overnight trips.

With its compact 18-inch dome design and advanced target resolution settings, the GMR Fantom 18x helps you adjust the on-screen presentation for optimal clarity based on your surroundings, separating closely grouped objects more effectively. It integrates seamlessly with compatible Garmin chartplotters, including GPSMAP™ series and ECHOMAP™ Ultra units, making it a powerful addition for offshore cruisers, salmon charter boats, and coastal navigators around Vancouver Island and Pacific Northwest waters.
