Garmin GMR 434 xHD3 4' Open Array Radar and Pedestal (4kW) (White)

Garmin GMR 434 xHD3 4' Open Array Radar and Pedestal - 4kW (K10-00012-24)

Dominate offshore navigation and fish-finding with the Garmin GMR™ 434 xHD3 4' Open Array Radar & Pedestal (4 kW)—a powerhouse marine radar system built for precision, safety, and situational awareness. Designed for serious mariners who demand top-tier performance, this rugged open-array radar delivers sharp target definition and unmatched capability in challenging marine environments.

• Scan with the full magnetron power of Garmin’s open-array radar platform, combining high-definition imaging and advanced radar tech for superior detection of weather cells, obstacles, and vessel traffic.
• Offers a maximum range of up to 72 nautical miles, making it ideal for both offshore cruising and serious fishing expeditions.
• Scan Averaging Technology filters sea clutter and interference to enhance consistent target returns—first-of-its-kind in a Garmin magnetron radar.
• Angular Target-Size Adjustment and pulse-expansion processing refine the shape and clarity of targets across all ranges for easier interpretation.
• True Echo Trails display a historical track of moving contacts, eliminating relative motion effects to help you spot collision threats faster.
• Supports Dual-Range / Split-Screen Display: view separate short and long-range sectors side by side on compatible chartplotters, and overlay one or both on your map view.
• Dynamic Auto Gain continuously optimizes gain settings for harbor, near-shore, and open water, with built-in Dynamic Sea Filter adapting to calm or rough seas.
• Radar Overlay capability lets you show radar returns directly on your chart plotter’s map screen (with compatible sensors and chartplotter).
• High-Resolution Radar benefits from a narrow 1.8° horizontal beamwidth and high antenna gain, enabling detection of small targets at greater distances.
• Dual-Radar Support allows redundancy and multiple display units to pull data from distinct radars for extra safety.
• Auto Bird Gain helps you locate flocks of birds (and associated baitfish) on the sea surface—critical for targeting fishing zones.
• MARPA Target Tracking supports tracking of up to 30 targets (with requisite heading/heading sensor setup), aiding collision avoidance and tactical maneuvers.
• Guard Zone & Range/Bearing Cues let you define safety zones, get alarms on zone intrusion, and rapidly measure range or bearings to vessels or land features.
