Discover Unmatched Performance with the Raymarine Magnum 4' Open Array Radar

Engineered for those who demand the best from their marine radar, the Raymarine Magnum 4' array stands out as a compact yet powerhouse option in open array technology. Ideal for serious boaters, fishing charters, and offshore adventurers, this 4-foot antenna pairs seamlessly with high-output pedestals to deliver exceptional target detection across vast distances. Whether navigating crowded harbors or scanning distant horizons, its precise beam width of 1.85 degrees horizontal and 25 degrees vertical ensures sharp, reliable imaging even in challenging conditions.

Why Boaters Trust This Radar for Superior Situational Awareness

At the heart of its appeal lies a 12-kilowatt power output that pushes detection ranges up to impressive nautical miles, spotting everything from massive vessels to small buoys with clarity. Operating at speeds between 24 and 48 RPM, it provides smooth, real-time sweeps without lag, crucial during high-speed pursuits or evasive maneuvers. Built tough with an IPX6 waterproof rating, it shrugs off heavy rain, spray, and salt exposure, making it a staple for professional crews who can't afford downtime.

Unlike bulkier systems, the 4' array strikes a perfect balance between performance and space efficiency. Mount it on sportfishers, yachts, or workboats where every inch counts, and enjoy enhanced resolution that rivals larger arrays. Marine pros often highlight its magnetron-driven pulse compression, which sharpens echoes for map-like coastal details, turning foggy seas into a clear tactical display.

Advanced Features That Elevate Your On-Water Experience

• Exceptional Bird Detection: Pinpoint flocks up to several nautical miles out, guiding you straight to baitfish schools and saving precious fuel on long hunts.
• Beam Sharpening Tech: Achieve sub-1-degree resolution for separating closely packed targets, vital in busy shipping lanes or during night operations.
• Automatic Target Tracking (MARPA): Lock onto and monitor multiple contacts effortlessly, with 9-axis heading data for pinpoint accuracy.
• True Motion Trails: Visualize vessel wakes in real time, predicting courses and avoiding collisions with confidence.
• Dynamic Heading Updates: Seamless display rotation during turns, keeping your radar picture stable and intuitive.

Seamless Integration Across Raymarine Ecosystems

This array shines brightest when connected to modern multifunction displays running intuitive operating systems. It overlays radar data flawlessly with charts, sonar, and AIS, creating a unified command center. Even older compatible units benefit from core functions, ensuring longevity for upgraded setups. Power it reliably with 12-volt systems common on most vessels, and you're ready for extended voyages without constant battery worries.

Real-World Applications and Pro Tips

For offshore anglers, the superior bird mode transforms scouting trips, spotting surface disturbances that signal hot spots below. Commercial operators value its long-range prowess for collision avoidance in fog or at dusk, while recreational cruisers appreciate the compact design that doesn't overwhelm sleek deck layouts. To maximize performance, position the array high and forward, minimizing obstructions for the cleanest sweeps. Regularly clean the radome to maintain peak sensitivity, and calibrate heading sensors for flawless tracking.

Compared to 6-foot options, this 4' model offers quicker installation and less wind resistance at speed, without sacrificing core range or detail—perfect if you're balancing power with practicality.

Built for Endurance in Harsh Marine Environments

White-finished for visibility and corrosion resistance, the array endures years of pounding waves and UV exposure. Its open design promotes airflow, cooling critical components during intense use, while the pedestal mount (sold separately) handles the rotation with precision engineering trusted by coast guards worldwide.
