Garmin GMR™ 436 xHD3 6' Open Array Radar & Pedestal - 4kW
Garmin GMR™ 436 xHD3 6' Open Array Radar & Pedestal - 4kW — Product description
Navigating challenging offshore waters demands radar that delivers crystal-clear detection without missing a beat. The Garmin GMR 436 xHD3 stands out with its 6-foot open-array design, blending magnetron power and cutting-edge processing for mariners who push boundaries. Whether you're chasing big game fish far from shore or threading through congested shipping lanes, this 4kW powerhouse uncovers hidden obstacles, tracks vessels with precision, and pierces through rain and fog to keep you safe and informed.
Advanced Detection Technologies for Real-World Boating
Engineered for the demands of serious offshore adventures, this radar goes beyond basic scanning. Its innovative features turn raw signals into actionable insights, helping you make split-second decisions.
Scan Averaging for Cleaner, More Reliable Images
Sea clutter and random noise can obscure critical targets, but Garmin's exclusive Scan Averaging smooths out these distractions over multiple sweeps. The result? Sharper echoes of buoys, debris, and approaching boats, even in choppy conditions—ideal for low-light dawn patrols or stormy evenings.
True Echo Trails to Spot Movement Instantly
Forget guesswork with relative motion displays. True Echo Trails show the actual path of moving objects, stripping away your boat's speed to reveal true courses and closing speeds. Spot potential collisions early, whether it's a freighter crossing your path or a fellow angler drifting too close.
Dual-Range Flexibility with Chart Overlay
Split your screen to monitor short-range harbor details alongside long-range horizon scans—up to 72 nautical miles. Overlay both on your chartplotter for a unified view, letting you zoom in on nearby rocks while keeping an eye on distant thunderheads.
- Dynamic Auto Gain and Sea Filter: Automatically tunes for calm inlets, moderate swells, or heavy seas, maintaining optimal visibility without constant tweaks.
- Auto Bird Gain: Highlights bird flocks signaling bait balls below, a game-changer for offshore trolling.
- MARPA Tracking: Locks onto and follows up to 30 targets, calculating speed, course, and CPA (Closest Point of Approach) for collision avoidance.
Built Tough for Extreme Marine Environments
Rated for 100-knot winds with the right setup, this radar's quiet motor and sturdy pedestal handle brutal conditions silently. High-resolution narrow beamwidth (1.1° horizontal) separates targets like individual birds in a flock or closely packed pots, while 23° vertical coverage ensures nothing slips under the radar—literally.
Fishermen love its baitfish-locating prowess; cruisers rely on Guard Zones that trigger alarms for intruders in your safe bubble. Dual-radar support adds redundancy, feeding data to multiple displays for crew coordination.

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 chartplotter’s 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 water’s 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.
