Professional-Grade Marine Radar System for Serious Navigation
The Raymarine 4kW Magnum T70408 delivers Coast Guard-trusted radar technology in a complete package designed for vessels requiring reliable long-range detection and precision target tracking. This high-performance open array radar system combines a 4-foot antenna array with advanced beam sharpening technology to provide unmatched small target imaging and superior situational awareness up to 72 nautical miles.
Advanced bird identification system targets avian life with exceptional clarity up to 10 nautical miles, helping sport fishing vessels locate schooling baitfish more efficiently while reducing fuel consumption. This specialized mode builds upon Raymarine's proven bird detection algorithms for enhanced fishing success.
Proprietary Raymarine beam sharpening technology delivers better than 1-degree bearing resolution, providing:
Fully automatic MARPA (Mini Automatic Radar Plotting Aid) target acquisition and tracking system utilizes Evolution 9-axis heading sensor technology for:
Revolutionary True Trails feature displays historical "wake" patterns behind moving contacts, enabling mariners to:
When connected to Axiom displays with LightHouse 3, experience uninterrupted radar imagery during course changes. The display rotates seamlessly without refresh delays, maintaining constant target visibility during critical navigation maneuvers.

The Raymarine 4kW Magnum T70408 excels in various marine applications:
This radar system employs the same proven technologies trusted by the United States Coast Guard, ensuring:
The 4kW Magnum provides maximum range capability up to 72 nautical miles, ideal for coastal and offshore navigation applications.
While not mandatory, professional installation by ABYC-certified marine electronics technicians ensures optimal performance, proper grounding, and warranty compliance.
The Magnum system is specifically designed for Raymarine multifunction displays. Third-party compatibility is not supported or recommended.
Regular inspection of rotation mechanism, antenna connections, and protective radome cleaning. Annual professional service recommended for optimal longevity.
Bird Mode detects diving seabirds up to 10nm away, indicating baitfish schools below. This significantly reduces fuel costs and increases fishing success rates.
The included VCM100 converter handles both 12V and 24V DC systems. A dedicated 15-amp circuit breaker is recommended for optimal power delivery.
The Raymarine 4kW Magnum T70408 represents the pinnacle of open array radar technology for serious mariners. With Coast Guard-proven performance, advanced target tracking, and comprehensive display compatibility, this system delivers the reliability and precision demanded by professional and recreational operators navigating today's busy waterways.
4kW Magnum with 4' Array & 15M RayNet Radar Cable
High Performance, Long Range Open Array Radar
Magnum high performance open array radars bring long range performance and unmatched small target radar imaging to Raymarine multifunction navigation displays. Employing many of the same radar technologies trusted by the United States Coast Guard, Magnum offers enhanced target tracking and reliable performance, all packaged in a sleek open-array pedestal built to withstand the elements.
Key Features:
Magnum is available in 4kW or 12kW power output options, and with either a four-foot or six-foot antenna array option. It offers a maximum range up to 96nm for 12kW models – ideal for blue water vessels – and up to 72nm for 4kW models. The perfect companion to Raymarine’s award-winning Axiom® and Axiom Pro multifunction navigation displays (MFD) running LightHouse 3, Magnum is also backwards compatible with legacy models including:
*Note: Not all Magnum features are available on all legacy MFDs.
Superior Bird Mode
Building upon Raymarine’s already exceptional bird identification technology, we have further advanced Magnum’s Bird Mode feature to target birds with greater clarity up to 10nm. Locating flocks of birds with Magnum helps anglers find schooling baitfish faster and with less fuel consumption.
Enhanced Radar Imaging
Magnum radar also features Raymarine beam sharpening technology, delivering better than 1-degree bearing resolution for more detailed target separation, map-like coastal detail, and superior long-range performance.
Best in Class Target Tracking
Magnum delivers better situational awareness with fully automatic MARPA target acquisition and tracking. Magnum also makes use of Raymarine’s Evolution 9-axis heading sensor technology to deliver real-time, accurate target plots.
True Trails
Magnum features True Trails target history. The True Trails features enables you to see a historical “wake” behind every moving contact. This additional information makes it even easier to interpret the motion of other vessels and make smart maneuvering decisions to pass safely.
Real Time Heading Updates
Connect Magnum with Axiom and LightHouse 3 and experience uninterrupted radar target imagery when making course changes. Real Time Heading updates allow the radar position display to rotate freely as-needed, without the need to refresh the entire display.
