Garmin GMR™ 1234 xHD3 4' Open Array Radar & Pedestal - 12kW

Imagine slicing through fog-shrouded waters or navigating stormy seas with crystal-clear visibility of distant threats, birds signaling prime fishing grounds, or approaching vessels. The Garmin GMR 1234 xHD3 delivers that edge with its powerhouse 12kW magnetron-driven performance, tailored for offshore adventurers who demand reliability without compromise. This 4-foot open-array system pairs razor-sharp resolution with intuitive controls, transforming your chartplotter into a command center for safer, smarter voyages.

Unlock Next-Level Detection Capabilities

At the heart of this radar lies cutting-edge scan averaging, a breakthrough in magnetron tech that smooths out choppy sea clutter and pesky interference. The result? Targets like buoys, debris, or fellow boaters pop into view with stunning consistency, even in rough conditions. Pair it with angular target-size adjustment, which refines pulse expansion to shape objects accurately across any zoom level—making split-second decisions easier when seconds count.

True echo trails add another layer of situational awareness, painting a motion-independent history of nearby contacts. Spot a crossing freighter's path at a glance and gauge collision risks before they escalate. For dual-range fans, overlay short- and long-range feeds side-by-side on your display, customizing each independently while superimposing them on charts for unmatched context.

Engineered for Real-World Marine Challenges

Dynamic auto gain and sea filters adapt on the fly, dialing in perfect settings from tight harbors to vast open oceans or swelling waves. Auto bird gain is a game-changer for anglers, highlighting surface flocks that betray bait balls below. High-resolution imaging, fueled by a narrow 1.8-degree horizontal beamwidth, lets you resolve fine details up to 96 nautical miles out—ideal for early weather cell spotting or distant landfalls.

Built tough with IPX6 waterproofing and a whisper-quiet drive motor, it shrugs off 80-knot winds (upgradable to 100 knots). Dual-radar support means redundancy across multiple stations, while MARPA tracks up to 30 targets with precision. Set guard zones for instant alerts, or drop variable range markers and bearing lines for quick bearings—tools that pros swear by for collision avoidance and precise maneuvering.

Compact Yet Mighty Footprint

The 4-foot array measures a sleek 52.2 x 4.8 x 6.7 inches, topping out at 27.7 kg with the pedestal (20.5 x 12.9 x 12.4 inches). It spins at 24 or 48 RPM on 10-32V DC power, sipping just 18W in standby and 70W transmitting—efficient enough for extended trips without draining batteries.

Why Offshore Mariners Choose This Radar

Fishermen revel in its bird-finding prowess and clutter-free long-range scans for spotting structure. Cruisers lean on radar overlay for seamless chart integration, blending echoes with GPS plots to dodge uncharted hazards. Tournament pros and commercial operators value the commercial-grade wind tolerance and pedestal stability, ensuring uptime when conditions turn brutal. Unlike dome radars, this open array's high gain and beam focus deliver the horizon-spanning punch needed beyond coastal hops.

Integration is straightforward with Garmin's ecosystem—network it to compatible plotters for overlay magic, guard zones, and more. Whether chasing tuna at dawn or threading night passages, it elevates confidence, cutting through uncertainty with data you can trust.
