The Raymarine Magnum open array radar is designed for serious offshore vessels that require powerful long-range radar performance and reliable target tracking.
Magnum radar uses a traditional high-power magnetron transmitter and is available in both 4kW and 12kW power options, combined with either a 4-foot or 6-foot open array antenna. The longer antenna improves radar beam width and target separation, allowing skippers to distinguish vessels, land and weather systems more clearly when operating offshore.
The 4kW Magnum radar provides detection ranges of up to approximately 72 nautical miles, making it ideal for coastal navigation, collision avoidance and weather monitoring. The 12kW Magnum radar increases transmitter power and sensitivity, extending detection ranges up to around 96 nautical miles, which is particularly useful for offshore vessels and game fishing boats.
Raymarine Magnum radars integrate directly with Raymarine Axiom chartplotters and other compatible Raymarine multifunction displays, providing radar overlay, MARPA target tracking and advanced navigation features directly on the chartplotter screen.
Raymarine Magnum Radar Features
- Long range radar performance with detection ranges up to approximately 96 nautical miles on 12kW models.
- High resolution radar imaging with beam sharpening technology for improved target separation.
- Bird mode detection to help offshore anglers locate bait schools by identifying bird activity.
- Automatic MARPA target tracking to monitor nearby vessels and improve situational awareness.
- True Trails target history showing the direction and movement of radar contacts.
- Real-time heading updates for smooth radar overlay when changing course.
Compatible Raymarine Displays
Magnum radar integrates with Raymarine multifunction displays running the LightHouse operating system including the Raymarine Axiom and Axiom Pro series. It is also compatible with several earlier Raymarine display platforms.
When paired with a Raymarine chartplotter, Magnum radar allows skippers to overlay radar targets directly on navigation charts, improving awareness of nearby vessels, land and weather when running offshore or navigating in reduced visibility.
Raymarine Magnum Radar Options
The Raymarine Magnum radar is available in four main configurations depending on the power level and antenna size required for your vessel.
- 4kW Magnum with 4ft Open Array – Compact open array radar suitable for mid-size vessels and coastal navigation.
- 4kW Magnum with 6ft Open Array – Improved target separation and longer range radar performance.
- 12kW Magnum with 4ft Open Array – Higher transmitter power designed for offshore navigation.
- 12kW Magnum with 6ft Open Array – Maximum performance for large offshore vessels and serious game fishing boats.
Each Magnum radar package includes the radar pedestal, open array antenna and RayNet radar cable required to connect to compatible Raymarine multifunction displays.
If you're running offshore or chasing fish wide, a good radar setup makes a huge difference. The Raymarine Magnum open array radar is built for serious range and target tracking, especially when paired with the latest Raymarine Axiom chartplotters. On smaller boats a lot of skippers go for the Raymarine Quantum radar, which is a compact solid-state radar that still gives great performance for coastal runs and trailer boats. If you're comparing radar systems, you can also browse the full Raymarine radar range to see which setup suits your boat and the way you fish.
Raymarine Magnum Radar FAQ
What is the range of Raymarine Magnum radar?
Raymarine Magnum open array radar systems offer long-range detection of up to 96 nautical miles depending on the model. The 4kW Magnum radar provides up to 72 nautical miles, while the 12kW Magnum radar provides extended offshore detection capability.
What is the difference between 4ft and 6ft Magnum radar antennas?
The 6-foot open array antenna provides improved radar beam width and target separation compared to the 4-foot antenna. This allows the radar to better distinguish between closely spaced targets such as vessels, navigation markers and land features.
Does Raymarine Magnum radar work with Axiom chartplotters?
Yes. Raymarine Magnum radar integrates directly with Raymarine Axiom chartplotters and other Raymarine multifunction displays, enabling radar overlay, MARPA target tracking and full radar control.
What is Bird Mode on Raymarine Magnum radar?
Bird Mode is designed to help anglers locate flocks of birds that often indicate baitfish and feeding pelagic species. Magnum radar can detect bird activity at distances of up to around 10 nautical miles in suitable conditions.
Is Magnum radar suitable for offshore boats?
Yes. Magnum open array radar systems are designed for serious offshore vessels, sport fishing boats and commercial vessels that require long-range radar performance and strong target detection in all weather conditions.
