Introducing Raymarine Quantum 2 Radar with Doppler collision avoidance technology. The Quantum 2 next generation CHIRP pulse compression radar by Raymarine provides superior target awareness at both long and extremely short ranges.

Using advanced Doppler processing, the system instantly highlights moving radar contacts and color codes them to indicate whether they are inbound or outbound. Quantum with Doppler makes it easy to discern potentially dangerous targets when navigating in high-traffic areas.


  • Doppler moving target display allows for superior situational awareness at-a-glance
  • Fully automatic MARPA target tracking, along with manual MARPA mode
  • Adjustable TrueTrails target history shows the motion history of moving contacts
  • CHIRP Pulse Compression detects contacts as close as 18-feet for zero-visibility navigation
  • 24-mile range for early detection of traffic, navigation aids, landfall and weather
  • Immediate awareness – Quantum starts up and is ready to go in seconds
  • Superior interference rejection eliminates noise from other radars
