Garmin GMR Fantom™ 18 Dome Radar Product Description

Enhance Your Boating Safety with Advanced Doppler Radar Technology

Imagine navigating busy waterways or open seas with confidence, spotting potential hazards before they become problems. The Garmin GMR Fantom 18 dome radar brings this reality to life through its innovative solid-state design and MotionScope technology. This 18-inch unit delivers sharp, real-time imagery that differentiates moving targets—like approaching vessels or shifting weather fronts—using color-coded Doppler shifts. Whether you're dodging collisions in fog-shrouded channels or chasing productive fishing grounds, its pulse compression ensures crisp separation of objects from clutter, even at extended distances.

Boaters appreciate how this radar overlays seamlessly onto chartplotter screens, turning raw data into actionable insights. Its high-resolution 5.2-degree beamwidth slices through rain and mist, painting shorelines, boats, and storms with precision that traditional systems struggle to match.

Unlock the Power of MotionScope for Proactive Navigation

MotionScope leverages the Doppler effect—a shift in radar wave frequency caused by an object's movement—to instantly identify and color-code targets. Red hues signal inbound threats demanding immediate attention, while green denotes objects receding safely. This isn't just a gimmick; it's a game-changer for collision avoidance, revealing vessels crossing your path amid heavy traffic or flocks of diving birds marking baitfish below.

Complementing this, features like adjustable target sizing let you customize visuals for your environment, while echo trails leave fading paths behind movers, corrected for your vessel's heading when paired with compatible sensors. Fishermen rave about Auto Bird Gain, which amplifies faint surface returns to pinpoint avian activity without manual tweaking.

Superior Detection and Versatility Across Ranges

From intimate 20-foot scans of nearby docks to 48-nautical-mile sweeps of the horizon, this 40W powerhouse maintains consistent performance. Dual Range mode splits your display, letting one side monitor short-range obstacles while the other tracks distant squalls—ideal for multi-tasking on long passages.

Advanced tools elevate situational awareness: MARPA tracks up to 10 targets automatically, Guard Zones trigger alerts for intruders, and VRM/EBL tools measure distances and bearings swiftly. Dynamic Auto Gain and Sea Filters adapt on the fly to choppy waters or calm seas, ensuring clutter-free images without constant adjustments. Support for dual radars adds redundancy, perfect for larger vessels with multiple stations.

  • Instant Readiness: Solid-state means no warm-up delays—power on and go at 24 or 48 RPM rotations for balanced power use and updates.
  • Energy Efficient: Low draw keeps batteries happy during extended outings.
  • Overlay Magic: Radar data fuses with charts for a unified view (heading input enhances accuracy).

Fishing and Cruising: Tailored Tools for Real-World Adventures

For anglers, the real magic happens when birds bunch over structure—MotionScope and Auto Bird Gain turn those signals into hot spots, guiding you to feeding frenzies. Cruisers benefit from weather tracking, watching cells build and dissipate to skirt storms proactively.

Pro tip: In variable conditions, toggle between low, medium, and high sea clutter settings to dial in perfection. Pairing with an autopilot stabilizes trails, making threat assessment intuitive even solo. This radar isn't just equipment; it's an extension of your instincts, freeing you to focus on the journey.

Effortless Setup and Intuitive Operation

Designed for real boaters, installation boils down to mounting the dome, connecting power and network cables, and you're operational—no PhD in electronics required. User-friendly defaults handle 95% of scenarios, with simple menus for the rest. Reliable in rain, fog, or sun, it demands minimal maintenance, letting you spend more time on the water.

GMR Fantom™ 

18-inch Dome Radar with MotionScope™ Technology

  • 18-inch, 40 W solid-state, dome radar
  • MotionScope™ technology uses the Doppler effect to detect and highlight targets moving toward you or away in different colors to help avoid collisions, find flocks of birds, and track weather
  • Pulse Compression technology provides high resolution while maximizing energy, to enhance detection and identification of targets
  • Target Size allows you to adjust the size of objects on the radar image
  • 20 foot to 48 nautical mile detection range

The 18-inch, 40 W solid-state Garmin GMR Fantom 18 dome radar features MotionScope technology, which uses the Doppler effect to detect and highlight moving targets to help you avoid potential collisions. Fully integrates with select Garmin chartplotters.

High-power 40 W Radar with 5.2 Degree Beam

You get excellent close- and long-range target detection ranging from as close as 20 feet to 48 nautical miles, even in fog or rain. Its 5.2 degree horizontal beamwidth provides a high resolution image and high antenna gain so it can pick out targets at a distance. The result is this radar paints a clear, concise image of the shoreline, other vessels and impending weather — right on your Garmin chartplotter. You get consistent target positions, excellent target separation and reliable operation. Its 8-bit true color imagery also helps you discriminate large targets from small ones and enhances target separation. Radar data is overlaid onto charts (autopilot or heading sensor recommended). Low power consumption, instant turn on and no delay from warming up as with magnetron radars. Rotation speeds of 24 for reduced power consumption and 48 rpm to provide fast screen updates.

MotionScope Doppler Technology

GMR Fantom radars use the Doppler effect to detect and highlight moving targets to help you avoid potential collisions, find flocks of birds and track weather formations. The Doppler effect is the frequency shift in the radar echo due to the relative motion of the target. This allows for instant detection of any targets moving toward or away from the radar. MotionScope highlights the moving targets in different colors on the radar display so you can navigate around other boats or severe weather, or toward fishing spots where birds are feeding at the surface.

  • Target Size: Allows you to adjust the size of objects on the radar image.
  • Auto Bird Gain: Fishermen know, when you find birds at the water’s surface, you’ll also find fish. To further improve your fishing experience, use Auto Bird Gain, which helps to locate flocks of birds at the water’s surface where baitfish are also likely to be found.
  • Echo Trails: A fading “trail” is left on the screen to help you quickly and easily identify moving targets and potential collision threats. Trails are corrected for your boat’s rotation when an autopilot or heading sensor is connected to your Garmin network.
  • Dual Range: Single radar antenna is capable of providing split screen images on your chartplotter side-by-side, with independent range setting and controls for both close and long range.
  • Dual Radar Support: Provides redundancy and the ability for each display unit on the boat to select data from 1 of 2 different radar sources.
  • Dynamic Auto Gain: Dynamic Auto Gain automatically adjusts to your surroundings for optimal performance in all conditions.
  • Dynamic Sea Filter: Dynamic Sea Filter automatically adjusts gain to changing sea conditions with user options for low, medium or high filtering.
  • Radar Overlay: Overlays the radar image on the chartplotter’s map page. An autopilot or heading sensor is recommended for best results.
  • MARPA Target Tracking: Mini-automatic radar plotting aid (MARPA) tracks up to 10 selected targets, helping you keep track of other vessels and avoid collisions.
  • Guard Zone: Set the safety zone and receive an alarm when an object enters the zone.
  • VRM and EBL: Variable range markers (VRM) and electronic bearing lines (EBL) allow rapid measurements of distance and bearing to vessels and land.
