• Advanced Imaging: Features beam sharpening technology that provides better than 1-degree bearing resolution, ensuring superior target separation and detailed coastal mapping.
• Bird Mode: Includes a specialized mode that identifies flocks of birds up to 10nm away, a critical tool for anglers locating schooling baitfish.
• Situational Awareness:
  • MARPA Target Tracking: Fully automated target acquisition and tracking for enhanced safety.
  • True Trails: Displays a historical "wake" behind moving contacts to easily interpret vessel motion.
  • Real-Time Refresh: When paired with Axiom displays and heading sensors, the radar image updates instantly during course changes without full-screen refreshes. 

Raymarine 4kW Magnum with Open Array and 15m RayNet Radar Cable FAQs

• What is the maximum range of the 4kW Magnum radar?
  The maximum range scale for the Raymarine 4kW Magnum radar is 72 nautical miles (nm). Actual target detection range will vary based on mounting height and target size.
• What are the power requirements?
  The system operates on 12 V DC or 24 V DC systems, with an operating voltage range of 10.8 V DC to 32 V DC, using the supplied VCM100 Voltage Converter Module.
  • Power Consumption (Typical Transmit): Less than 70 W.
  • Power Consumption (Standby): Less than 30 W.
  • Power Consumption (Sleep): Less than 1.2 W.
• What is the antenna beam width and rotation speed?
  The 6-foot open array version has a nominal horizontal beam width of 1.15° (less than 1° effective after beam sharpening), and a vertical beam width of 25°. The rotation speed is either 24 RPM or 48 RPM, with the high-speed mode automatically engaging at ranges of 3 miles or less (MFD dependent).
• What is the IP (Ingress Protection) rating?
  The system has a waterproofing standard of IPX6, meaning it is protected against heavy seas or powerful jets of water.
• Which Raymarine displays are compatible?
• Magnum radars are compatible with Raymarine's Axiom and Axiom Pro multifunction displays (MFDs) running LightHouse 3 OS or later. It is also backward compatible with some legacy MFDs, including LightHouse 2-based a, c, e, eS, and gS-Series, as well as C-Series Widescreen and E-Series Widescreen displays.
• Can I use my existing radar cable?
  Typically, a new radar scanner requires a new interconnect cable. In some instances, an adapter cable might be available for specific older Raymarine Digital or HD Digital radar cables, so it's recommended to consult a Raymarine installer or technical support.
• Can the standard 15m RayNet cable be extended?
  Yes, Raymarine offers optional cable lengths of 5m, 10m, and 25m. It's important to use official Raymarine extension cables and avoid cutting or splicing the cable.
• What should the optimal mounting height be?
  Mounting the scanner as high as possible above the waterline improves long-range performance due to the line-of-sight nature of radar. It should also be mounted above head height for safety.
• Does the radar have a Bird Mode?
• All Raymarine Magnum radar models include a Bird Mode feature designed to help detect sea bird activity, which can indicate the presence of schooling baitfish.
• What is True Trails and how does it work?
  When connected to a heading sensor, the True Trails feature displays a historical trail behind moving contacts, aiding in the interpretation of vessel movement and collision avoidance.
• Can the radar detect weather?
  Yes, Raymarine radars can be used to monitor weather, detecting rain squalls and thunderstorms at a distance.
• Do I need a license to operate the radar?
  Installation and operation requirements may be subject to national administration licensing.
