Raymarine RD418HD HD Digital Radome Scanner - 18 Inch, 4KW - exc cable

HD Color Radar for Superior Target Detection and Interpretation.

Powerful processing helps distinguish between target types, detect weak and distant contacts automatically, while virtually eliminating clutter and noise. The truly adaptive transmitter and receiver automatically adjusts to changing environmental and sea conditions. With full 256 colour resolution, HD Color radar delivers a dramatically clearer radar picture with crisp, well-defined contact echoes, superior target separation, and a life-like target presentation.

Why radar? Where are you relative to your surroundings? Is there anything nearby that could be a danger to you, or vice versa? Radar is a great aid to navigation that allows you to:

  • 'See' other vessels, buoyage and coastline in zero visibility.
  • Track targets - not everything transmits AIS...
  • Double check your relative position and speed
  • Avoid hazards and obstacles
  • Track weather
  • Locate fish using bird mode!
Each Raymarine marine radar system consists of a Raymarine multifunction display and your choice of Raymarine radome or open array antenna.

Radomes - Digital or HD Color Radomes are ideal when power is at a premium and mounting space is limited or restricted by rigging. Perfect for sailboats, RIBs and smaller powerboats, radomes provide exceptional performance even in the most challenging conditions HD Color Radomes provide additional features and improved resolution.

Open Arrays - Choose an HD Color or Super HD Color open array scanner for enhanced performance and range. These larger scanners, equipped with a more efficient antenna (increased gain) and narrow beam widths, deliver substantial improvements in range and bearing resolution giving great performance and clear target separation.
