New Scan Averaging Technology

A first for Garmin magnetron radar, scan averaging helps filter out sea clutter and interference to enhance the detection and display of consistent targets.

Angular Target-Size Adjustment

Pulse expansion and angular target-size processing techniques optimize on-screen object shapes for better interpretation at all range scales.

True Echo Trails

A historical trail of boats on the water is displayed on the screen, removing relative motion influence to help you quickly identify moving targets and potential collision threats.

Dual Range with Overlay

A single radar antenna is capable of providing split-screen, side-by-side images on your compatible chartplotter, with independent range setting and controls for both close and long range. Overlay either or both ranges on a chart.

Dynamic Auto Gain

Gain automatically adjusts levels to optimum settings for harbors, near shore and offshore in open waters.

Radar Overlay

See overlaid images on your chartplotters map screen (with appropriate sensors, sold separately).

High-Resolution Radar

Pick out targets at a distance, thanks to narrow horizontal beamwidth and high antenna gain.

Dual-Radar Support

This provides redundancy and allows each display unit to pull data from different sources.

Dynamic Sea Filter

Radar gain automatically adjusts sea clutter for calm, medium and rough sea conditions.

Auto Bird Gain

Locate flocks of birds at the waters surface where baitfish are also likely to be found.

MARPA Target Tracking

Track up to 30 targets to help avoid collisions (with appropriate sensors, sold separately).

Guard Zone

Set the safety zone, and receive an alarm when an object enters the zone.

Range and Bearing Cues

Variable range markers and electronic bearing lines allow rapid measurements of distance and bearing to vessels and land.

The Garmin GMR 434 xHD3 4' Open Array Radar with Pedestal offers advanced marine radar capabilities suitable for offshore cruising and fishing. Equipped with a powerful 4 kW magnetron and high-definition imaging, this radar provides reliable detection of weather, obstacles, and vessel traffic at ranges up to 72 nautical miles. Its compact design and robust construction make it ideal for demanding marine environments. The system features Scan Averaging Technology that effectively filters sea clutter and interference, resulting in clearer target detection and improved situational awareness. Angular Target-Size Adjustment optimizes the shape of on-screen objects for easier interpretation across all ranges, enhancing safety during navigation and fishing activities. The radar displays true echo trails that show boat movement over time, helping mariners quickly identify moving targets and potential collision threats without the influence of relative motion. Dual Range with Overlay allows a single antenna to deliver split-screen images on compatible chartplotters, with independent controls for close and long-range views, and the option to overlay ranges directly on charts for comprehensive situational awareness. Dynamic Auto Gain automatically adjusts signal levels based on environmental conditions, ensuring optimal performance whether near shore, in harbors, or offshore. The radar supports high-resolution imaging thanks to a narrow horizontal beamwidth and high antenna gain, making distant targets more discernible. With support for dual-radar configurations, redundancy is enhanced, and each display can pull data from different sources. Additional features include the Dynamic Sea Filter that adjusts sea clutter reduction based on sea state, and Auto Bird Gain to assist in locating surface bird flocks where baitfish are likely present. MARPA Target Tracking enables tracking of up to 30 targets for collision avoidance, with optional sensors sold separately. Guard Zone alarms notify operators when objects enter predefined safety zones, and Range and Bearing Cues facilitate quick measurements of distance and direction to vessels or land. The system includes a 48-inch antenna, mounting hardware, and comprehensive installation components. Its rugged IPX6 waterproof rating and wind load capacity of up to 80 knots (with optional upgrades) ensure durability in harsh marine conditions. Designed with user convenience in mind, the Garmin GMR 434 xHD3 combines advanced radar technology with versatile features, making it an essential tool for serious mariners seeking enhanced safety and navigation performance.
