Garmin GMR™ 2536 xHD3 6' Open Array Radar & Pedestal - 25kW — Product description

Enhance Your Offshore Adventures with Advanced Radar Detection

Imagine navigating through foggy mornings or scanning distant horizons for hidden obstacles while cruising offshore. This powerful marine radar system delivers crystal-clear imaging that turns uncertainty into confidence. Built for serious mariners who demand precision, it combines proven magnetron technology with cutting-edge processing to spot everything from approaching vessels to bird flocks signaling prime fishing spots.

Whether you're chasing big game fish miles from shore or ensuring safe passage in crowded waterways, its robust design handles real-world conditions effortlessly. Mariners rave about how it cuts through sea clutter like never before, revealing targets that lesser systems miss.

Key Technologies That Set It Apart

Revolutionary Scan Averaging: Sea clutter and random noise often plague traditional radars, but this innovation smooths out those distractions across multiple scans. The result? Sharper, more reliable echoes of boats, buoys, and land—perfect for low-visibility days when every detail counts.

Smart Target Shaping: Objects on your screen appear more naturally proportioned, thanks to pulse expansion and angular adjustments. Close-in markers look compact and defined, while distant ones stretch realistically, making it easier to gauge threats at any scale.

True Motion Trails: Watch vessels leave accurate "ghost trails" unaffected by your boat's movement. Spot speeders or collision risks instantly—no guesswork involved.

Split-screen radar display showing dual range with overlay on chartplotter
Split-screen dual range lets you monitor near and far simultaneously.

Versatile Dual-Range Mode: Split your display to watch short-range hazards alongside long-range scans, with independent controls. Overlay both on charts for a seamless navigation view that keeps your eyes where they belong—on the water.

Performance Built for the Toughest Conditions

  • Extreme Weather Resilience: Rated for high winds, it spins reliably even in gales, keeping you informed when others go dark.
  • Whisper-Quiet Operation: A refined drive motor minimizes vibration and noise, so you can enjoy the sounds of the sea without distraction.
  • Adaptive Filters: Dynamic auto gain and sea clutter suppression tweak settings on the fly for harbors, coastal runs, or open ocean swells.
  • Bird Detection Magic: Auto bird gain highlights surface flocks, guiding you straight to bait balls teeming with trophy fish.

Pair it with chartplotters for radar overlays that fuse real-time data with your maps, or add MARPA tracking for up to dozens of automated targets. Guard zones alert you to intruders, while range markers let you measure distances at a glance.

Real-World Applications for Boaters and Anglers

For offshore anglers, it uncovers fish-holding structure and vessels long before they appear on the horizon. Cruisers benefit from its collision avoidance tools during night passages or in shipping lanes. Even commercial operators appreciate the redundancy of dual-radar setups, ensuring no single point of failure.

Compact yet mighty, the 6-foot array integrates smoothly on larger vessels, with straightforward cabling that simplifies setup. Power it from standard marine batteries and watch it deliver peak performance without draining resources.

"This radar transformed our overnight trips—spotting traffic from 80+ miles out gives peace of mind nothing else can." – Experienced offshore captain

Frequently Asked Questions

What is the maximum detection range of this open-array radar?

It reaches up to 96 nautical miles, ideal for spotting distant targets like ships or weather cells during extended offshore voyages.

How does dual-range functionality work on this radar?

One antenna feeds split-screen views with separate range settings—one for close-in details, another for far-off scans—overlayable on charts for comprehensive awareness.

What wind speeds can this radar handle?

Standard rating supports up to 80 knots, with options for 100 knots, making it suitable for harsh marine environments.

Does it help with fishing by detecting birds?

Yes, auto bird gain automatically enhances flocks on the surface, often indicating baitfish concentrations below for targeted fishing.

What makes scan averaging better than standard radar processing?

By averaging multiple scans, it filters sea clutter and interference, sharpening consistent targets for clearer, more trustworthy displays.

Is this radar quiet during operation?

Absolutely—a specialized open-array motor runs smoothly and silently, reducing onboard noise for a more comfortable experience.

Can it track multiple moving targets?

With MARPA, it tracks up to 30 targets simultaneously, providing speed, course, and CPA data to prevent collisions.

Why Choose This Radar for Your Vessel

In a world of unpredictable waters, superior situational awareness isn't optional—it's essential. This system empowers you with pro-level tools in an accessible package, elevating safety and success on every outing. Ready to see farther and navigate smarter?

SCAN WITH THE MAGNETRON POWER OF GARMIN OPEN-ARRAY RADAR

Combining high-definition imaging with the latest Garmin platform technology, this robust 4’ open-array radar offer superior weather, obstacle and traffic detection for mariners cruising or fishing offshore.

  • Up to 96-nautical mile range
  • Scan Averaging Technology
  • Improved Target-Size Processing 
  • Split-Screen Dual-Range Display
  • 100-Knot Commercial Grade Wind Rating1 
  • Quiet Open-Array Drive Motor

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.
