GARMIN GMR 1226xHD2 Open Array Radar

Garmin GMR 1226 xHD2 Open Array Radar Overview
Key Features
• 12 kW output power and a 6-foot open antenna enhance long-range detection and echo clarity.
• The radar achieves a maximum detection range of 72 nautical miles, and with 24/48 RPM rotation speeds, it's suitable for both nearshore and offshore operations.
• A horizontal beamwidth of only 1.1° provides fine target resolution; 8-bit full-color echoes clearly distinguish between different targets.
Operational Convenience
• Simple operation and installation, no complex setup required.
• Smooth and quiet operation, no noise disturbance.
Advanced Features
• Pulse Expansion: Increases target echo energy and visible size.
• Auto Bird Gain: Detects surface bird flocks, indirectly indicating the location of schools of fish. • Echo Trails: Displays historical trajectory data for quick identification of moving objects and potential collision threats.
• Dual Range and Dual-Radar Support: Displays both near- and long-range images, supporting multiple radar sources simultaneously.
• Dynamic Auto Gain / Dynamic Sea Filter: Automatically adjusts gain and sea clutter filtering to suit varying navigation conditions.
• Radar Overlay and MARPA (30-target tracking): Overlays radar echoes onto the chart, enhancing navigation safety with tools such as warning zones, variable range indicators (VRMs), and electronic bearing lines (EBLs).
