Garmin GMR Fantom 24x Dome Radar - White

Enhance Your Boating Safety with Advanced Radar Detection

Navigating busy waterways or challenging weather demands reliable visibility beyond what your eyes can provide. The Garmin GMR Fantom 24x dome radar delivers crystal-clear detection up to 48 nautical miles, empowering you to spot distant vessels, obstacles, and even bird flocks indicating prime fishing spots. Its solid-state design ensures instant readiness without the warm-up delays of traditional magnetron radars, keeping you proactive on the water.

Whether you're cruising at speed or anchoring in fog, this 24-inch white dome radar integrates seamlessly with Garmin chartplotters, overlaying real-time radar data on your charts for unmatched situational awareness. Boaters praise its ability to cut through rain clutter while highlighting fast-approaching boats, reducing collision risks during peak traffic hours.

Standout Features for Real-World Boating

• MotionScope Doppler Technology: Watch moving targets light up in sweeping colors—red for closing in, green for receding—making it effortless to track speedboats or monitor storm cells from afar.
• Ultra-Fast 60 RPM Rotation: A fluid refresh rate captures high-speed action, ideal for competitive racing or towing water sports where split-second decisions matter.
• Smart Power Management: Dial in exactly the power you need with customizable save modes and second-by-second transmit scheduling, extending battery life on long offshore trips.
• True Echo Trails: Fading history lines on your display reveal target paths over time, helping you predict courses and avoid close calls intuitively.
• Dual Range Viewing: Split your screen to monitor short-range hazards alongside long-range traffic, with independent controls for precision in crowded marinas or open seas.
• Dynamic Adjustments: Auto Gain and Sea Filter adapt to waves, rain, or calm conditions, delivering clutter-free images without constant tweaking.
• Flexible Target Sizing: Fine-tune resolution to separate tightly packed targets, like a fleet of small craft during regattas.

Maximize Time on the Water with Efficient Power Use

Power isn't unlimited on board, so the Fantom 24x shines with its versatile consumption modes. Normal transmitting peaks at efficient levels for full performance, while Power Save drops draw for standby cruising. Set precise transmit intervals—active for 10 seconds, idle for 30—to sip power during overnight passages or fishing waits. This radar's 50-watt output punches above its weight, offering pro-level range without draining your house bank like heavier hitters.

Seamless Setup and Chartplotter Integration

Pair it with dual radars for backup on larger vessels, or overlay feeds directly on your Garmin maps for a fused navigation experience. Add a heading sensor for MARPA target tracking—up to 30 automated acquisitions—to mimic professional bridge setups. Installation is straightforward with included long-reach cables and hardware; most users mount it high on arches or masts for optimal horizon scans. Pro tip: Calibrate during daylight trials to baseline performance before night ops.

Frequently Asked Questions

What makes the Garmin GMR Fantom 24x different from traditional radars?

Unlike magnetron-based systems, this solid-state radar powers on instantly with no warm-up, offers Doppler MotionScope for color-coded moving targets, and includes granular power controls for efficiency.

How does MotionScope technology work on this radar?

It leverages the Doppler effect to detect motion, displaying approaching targets in red and receding ones in green or yellow on your chartplotter, enhancing collision avoidance.

Can I use this radar in heavy rain or fog?

Yes, its 48 nm range performs reliably in adverse weather, with Dynamic Sea Filter and Auto Gain minimizing clutter from rain or waves for clear target separation.

Does it support multiple chartplotters on my boat?

Absolutely—Dual Radar support lets multiple Garmin displays pull independent feeds, providing redundancy and customized views across your helm stations.

What's the best way to mount the Fantom 24x dome?

Mount it as high as possible on a sturdy arch, pole, or mast for maximum horizon clearance. Use the included template and hardware, ensuring clear 360-degree rotation.

How much power does it really use during extended trips?

Standby at 4W, transmitting up to 33W max. Power Save and timed transmit modes let you schedule low-duty cycles, preserving batteries for multi-day outings.

Is a heading sensor required for full functionality?

It's optional but recommended for MARPA auto-tracking and precise overlays. Basic features like MotionScope work without it.
