Experience precision at sea with the Garmin GMR Fantom 18x, a 50-watt solid-state dome radar engineered for clarity, speed, and intelligent power management. Available in a white or black housing to match your boat, this 18-inch dome comes with 15-meter cables for flexible installation and reliable performance from 20 feet to 48 nautical miles, with a 60 RPM rotation for rapid target updates.
MotionScope technology uses the Doppler effect to color-code moving targets, helping you distinguish boats, weather, and wildlife at a glance. High-resolution imagery and 8-bit true color enhance target separation, while motion trails let you quickly identify potential threats or opportunities on the water.
