Navigating challenging waters demands radar that delivers clarity and reliability without compromise. The Garmin GMR Fantom 24x dome radar stands out with its 50-watt solid-state power, providing exceptional target detection from intimate close-range scans to horizons up to 48 nautical miles. Ideal for boaters facing fog, heavy rain, or nighttime conditions, this black dome unit integrates seamlessly with compatible Garmin chartplotters, overlaying precise radar images onto your charts for unmatched situational awareness.

What sets it apart is the blend of advanced tech and practical power management. MotionScope Doppler processing paints moving vessels, birds, or weather in vivid colors—green for approaching threats, red for receding ones—letting you anticipate collisions or spot feeding frenzies effortlessly. Pair that with adjustable rotation speeds up to 60 RPM, and you get fluid, real-time updates even at high vessel speeds.

Core Capabilities That Enhance Every Voyage

• Superior Target Separation: Fine-tune target size settings to cut through clutter, distinguishing small craft from waves or debris in busy harbors or open seas.
• Intelligent Power Control: Switch between full-throttle performance and eco-mode; timed transmit down to seconds slashes consumption, extending your time underway on battery or generator power.
• True Echo Trails: Watch historical paths of moving objects unfold on-screen, making it simple to predict courses and avoid close calls.
• Dual Range Viewing: Split your display for simultaneous short- and long-range feeds, perfect for threading inlets while monitoring distant traffic.
• Redundant Dual Radar Setup: Link multiple units for backup coverage across chartplotters, ensuring no blind spots fleet-wide.
• Auto-Adjusting Filters: Dynamic gain and sea clutter adaptation handle calm bays to stormy swells automatically, keeping your view crystal clear without constant tweaks.

Real-World Edge for Anglers and Cruisers

For offshore anglers, AutoBird complexity reveals bird flocks over bait balls, guiding you straight to hot spots. Cruisers benefit from MARPA tracking—up to 30 targets with optional heading sensor—for hands-free collision avoidance. Overlay radar directly on charts, and add guard zones or variable range markers for pro-level precision measurements.

Seamless Integration Tips

Mount high and forward for optimal sweep. Network via Garmin Marine Network for plug-and-play with GPSMAP or other compatibles—no complex calibration needed. Solid-state design warms up instantly, unlike old magnetron radars, so you're scanning seconds after power-on. For peak Doppler accuracy, pair with a heading sensor.

GMR Fantom 24x Dome Radar - Black

See what's coming on your compatible chartplotter with GMR Fantom 24x 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.

Features:

• 24 50-watt solid-state dome radar features a long-range and improved target detection on your compatible chartplotter 
• Adjust on-screen target resolution for better separation based on your surroundings by using the target size feature
• Up to 60 RPM rotation speed for a refresh rate that can detect movement at any speed 
• The power save feature lets you draw more or less power based on the performance you need
• Timed transmit mode lets you specify active and inactive times down to seconds instead of minutes for reduced power consumption
• MotionScope technology uses the Doppler effect to detect moving targets and highlight targets on your compatible chartplotter in different colors as they move toward or away from you
• True echo trails leave a historical trail on your compatible chartplotter to help you quickly and easily identify moving targets and potential collision threats
• Dual range provides split-screen images on your compatible chartplotter with separate range settings and controls for both close and long range 
• Dual radar support allows each of your compatible chartplotters on your boat to pull data from one of two different radar sources to provide redundancy
• Dynamic Auto Gain automatically adjusts to your surroundings for optimal performance in all conditions
• Dynamic Sea Filter automatically adjusts sea clutter based on sea conditions
• Radar overlay displays radar images over maps on your compatible chartplotter
