Discover Superior Situational Awareness with Garmin GMR 24 xHD Radar

Navigating busy waterways or open ocean demands radar that delivers crystal-clear images without overwhelming you with adjustments. The Garmin GMR 24 xHD steps up as a 24-inch dome radar powerhouse, blending the precision of larger open-array systems into a compact, user-friendly package. Boaters appreciate its ability to cut through clutter, spot distant targets early, and overlay seamlessly onto compatible chartplotters for a unified view of your surroundings.

Whether you're dodging fog-shrouded hazards near shore or scanning horizons for commercial traffic offshore, this radar's high-definition processing ensures targets stand out sharply. Its intuitive design means you spend less time tweaking settings and more time boating confidently.

Standout Features That Enhance Your On-Water Experience

• High-Definition Clarity: 8-bit true color resolution provides exceptional target separation, reducing screen clutter for easier interpretation—even in rain or choppy seas.
• Dynamic Auto Gain and Sea Filter: Automatically optimizes settings based on conditions, with adjustable aggressiveness levels or manual overrides for personalized control.
• Dual Range Operation: Split your screen to monitor close-in obstacles and far-off vessels simultaneously, perfect for maneuvering in harbors or cruising long distances.
• No Transmit Zone Option: Shields sensitive areas behind the unit from radiation, opening up creative mounting spots without compromising forward coverage.
• MARPA Target Tracking: Automatic radar plotting aid for collision avoidance—pairs with a heading sensor and multifunction display to track up to 20 targets.
• High-Speed Rotation: Select 24 or 48 RPM for rapid refreshes, auto-adjusting to match your selected range scale.
• Radar Overlay: Superimpose real-time radar data on your chartplotter maps for intuitive navigation.

Technical Specs at a Glance

Why Boaters Trust This Radar for Safety and Performance

Picture this: You're approaching a congested inlet at dusk. The GMR 24 xHD's narrow beam width picks out small craft and buoys with pinpoint accuracy, while its guard zones alert you to encroaching threats. In open water, the 48 nm range gives ample warning of squalls or ships, letting you plot safe courses effortlessly.

Unlike basic radars that demand constant fiddling, this unit's plug-and-play simplicity shines. Connect via the Garmin Marine Network to compatible plotters for instant overlay—no fuss. Its rugged build withstands harsh marine environments, backed by Garmin's reputation for reliability. For mid-sized vessels, it strikes the perfect balance of power and compactness, outperforming standard domes without the wind resistance of open arrays.

Effortless Installation and Seamless Integration

Mounting is straightforward with included hardware and a template for precise alignment. The 15m power and network cables reach most console setups, and the grommet ensures clean cable runs. Position it high and forward-facing for optimal coverage; the No Transmit Zone adds flexibility if space is tight near antennas or crew areas.

For peak performance, integrate with a Garmin autopilot or heading sensor. It thrives on Garmin chartplotters but plays well with other NMEA 2000/0183 networks. Most users report setup in under an hour, with auto-calibration handling the rest.
