Exceptional performance, even in the most challenging conditions

Digital and HD color Radome Radars offer the latest in power and technology.


SeaTalkHS connectivity and Raymarine's Auto GST technology provides enhanced small target returns and eliminates clutter caused by rain and sea conditions automatically through your Multifunction Display.

Each Raymarine Radar System consists of a Raymarine multifunction display (excluding A Series displays), and your choice of Raymarine radome or open array antenna.


Raymarine Digital Radome Antennas (RD418D & RD424D)


    • 48 NM range
    • Plug and Play compatibility
    • Improved radiation pattern and bearing resolution using Propagation Enhancing Geometry
    • Same mounting pattern as previous generation radomes
    • Utilizes small SeaTalkHS interconnect cable for ease of installation


Raymarine HD Color Radome Scanners (RD418HD & RD424HD)


  • 48 NM range
  • Adaptive digital receiver automatically adjusts to changing environmental and sea conditions for a dramatically clearer picture
  • 256 color multi-level target display with selectable color palettes
  • Bird Mode automatically optimizes the receiver for detecting sea birds above schools of fish
  • Dual-range mode allow you to monitor both long and short ranges simultaneously with a single scanner and display
