Raymarine Quantum 2 CHIRP Radar with Doppler Collision Avoidance Technology

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 colour 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.

Like every Raymarine Quantum system, you’ll also benefit from a rugged and lightweight design that is super-easy to install.

Quantum 2 has very low power consumption making it especially friendly to vessels running exclusively on battery power.

Quantum 2 with Doppler can be installed in a traditional wired configuration, or use its built-in Wi-Fi technology to connect it to your Raymarine MFD.

The Quantum 2 with Doppler truly sets the standard for on the water safety and collision avoidance.


  • Doppler moving target display allows for superior situational awareness at-a-glance.
  • Fully automatic ARPA 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.
  • Simplified installation with Wi-Fi or thin wire network connectivity.
