GMR™ 436 xHD3 6′ Open-Array Radar & Pedestal – 4 kW (K10-00012-25)
Unlock full offshore visibility with Garmin’s flagship 6-foot open-array radar engineered for performance, precision, and reliability.
- Scan with magnetron-powered high-definition radar imaging, combining raw detection power with Garmin’s advanced platform intelligence
- Delivers detection of weather systems, obstacles, vessels, and marine hazards with clarity for cruising, offshore fishing, and ocean passage
- Up to 72 nautical mile range — far-reaching radar coverage for long-range threat spotting and navigation safety
- Scan Averaging Technology filters sea clutter and suppresses interference, producing cleaner echo returns and stable target tracking
- Improved Target-Size Processing & Angular Target-Size Adjustment — pulse expansion and angular scaling refine how objects appear on-screen at every zoom level
- True Echo Trails — historical motion trails remove relative motion bias, helping you identify vessel trajectories and collision threats quickly
- Split-Screen Dual-Range Display / Overlay Mode — view close-in and long-range echoes side by side or overlaid on the chart, with independent range settings
- Dynamic Auto Gain & Dynamic Sea Filter — adapt gain and clutter suppression automatically for harbor, nearshore, and open-sea conditions
- Auto Bird Gain — detect flocks floating on the water surface, useful for locating baitfish zones
- MARPA Target Tracking (30 targets) — actively track multiple moving targets (requires external heading sensor)
- Guard Zone & Alarm — define safety perimeters; receive audible/visual alerts when objects penetrate the zone
- Range & Bearing Cues — electronic bearing lines and variable range rings provide interactive measurement tools
- Supports dual radar redundancy — separate display units can pull data from independent radars
- Commercial-grade 100-knot wind rating (80 knots standard, upgradable) for rugged offshore performance
- Quiet open-array drive motor with selectable rotational speeds (24 and 48 RPM)
