Navigate with confidence even when fog rolls in or night falls with the Garmin GMR Fantom 18x dome radar. This 18-inch solid-state powerhouse delivers 50 watts of targeted power, scanning up to 48 nautical miles to spot distant vessels, buoys, and hazards long before they become problems. Boaters who demand precision in challenging conditions swear by its rapid refresh rates and intelligent target tracking, turning your chartplotter into a vigilant co-pilot.
Unlike traditional radars that guzzle power and take ages to warm up, the Fantom 18x starts instantly and offers flexible power management. Whether you're cruising coastal waters, chasing offshore fish, or anchoring in unfamiliar bays, its advanced features like MotionScope Doppler processing help you differentiate friend from foe on screen—moving targets glow in sweeping colors, making collision avoidance intuitive and stress-free.
Safety isn't just a feature; it's engineered into every rotation. With up to 60 RPM speeds, this radar refreshes images fast enough to track high-speed intruders, giving you seconds that count. Power-conscious skippers love the timed transmit mode, dialing in active scans to the second for extended battery life on long passages.
Fishermen, take note: AutoBird mode highlights surface-feeding flocks, guiding you to hot bites without guesswork. Pair it with dual radar setups for backup reliability across multiple stations.
Solid-state tech means no magnetron hazards—just reliable pulse compression for sharp, short pulses that mimic higher power without the bulk. The narrow 5.2° horizontal beam slices through rain clutter, while the 25° vertical spread ensures even low-profile targets like runabouts don't slip by. Overlay radar ghosts onto your Garmin charts for a fused reality view, enhancing situational awareness during autopilot runs or man-overboard drills.
Installation is a breeze for savvy owners: Masthead or arch mount with included hardware, 15-meter cables for flexible routing, and plug-and-play networking via Garmin Marine Network. IPX7 waterproofing shrugs off spray, and its compact 20" x 9.8" footprint fits tight spaces without sacrificing performance.
Running 10-32V DC, it sips just 4W on standby, spiking to 33W max transmit in normal mode. Switch to power save for 24W bursts, or schedule ultra-precise duty cycles to stretch generator runtime. Stay powered through the night watch without firing up auxiliaries.

It's a solid-state radar with instant-on capability, no warm-up time, and safer operation without magnetrons. Pulse compression delivers high-resolution images equivalent to more powerful units.
Using Doppler effect, it detects moving targets and colors them based on direction—approaching in one hue, receding in another—for quick threat assessment.
Absolutely. AutoBird mode identifies bird flocks over bait schools, and high-resolution imaging spots surface activity from afar.
Yes, with power save modes and timed transmit down to seconds, helping conserve battery on extended trips.
It integrates seamlessly with Garmin chartplotters via the Marine Network, supporting overlay, dual range, and advanced features.
IPX7 rated, it withstands submersion and harsh weather, built for years of reliable saltwater service.
Yes, with MARPA (requires heading sensor), it auto-acquires and tracks up to 30 targets, including guard zones.
GMR Fantom 18x Dome Radar - Black
See what's coming on your compatible chartplotter with GMR Fantom 18x dome radar. When visibility is low and situational awareness is crucial, you need a radar you can depend on. Get 50 watts of output power for long-range and better target detection. Confidently travel at higher speeds and detect boats approaching at high speeds with up to 60 RPM rotation speed. The power save feature lets you choose when you need more power or less, so you have power when you need it and can conserve it when you don't. With timed transmit mode, you can even specify active and inactive times down to the second to help reduce power consumption so you can stay on the water longer than ever. MotionScope technology helps detect moving targets and highlights them in different colors so you can navigate around other boats or severe weather.
