Black Q24D Quantum 2 Doppler Radar with 10M Power & Data Cables

Keep inexperienced boaters and hidden dangers at bay, even in the most congested waterways.

Quantum 2 with Doppler collision avoidance technology makes it easy to discern potentially dangerous targets when navigating in high-traffic areas. Using advanced Doppler processing, Quantum 2 instantly highlights moving radar contacts and color codes to indicate whether they are inbound or outbound.  


  • Black radome enclosure 
  • WiFi and Ethernet 
  • 10M power and data cables are included
  • Quantum 2 Doppler Radar, perfect for sailboats, RIBs, and smaller powerboats
  • Available as a standalone scanner with power and data cable 
  • Provides excellent short-range detection and enhanced target detail with an 18' (6m) minimum range
  • Simplified, fast installation, and the ability to utilize existing Raymarine scanner fixing points
  • Once installed, Quantum 2 starts right up and immediately provides awareness

Quantum 2 Black: Stay Aware With Style

Offering confident radar navigation and style, Quantum 2 Black adds a level of sophistication to any vessel. 

Quantum 2 Black offers the same performance and safety-enhancing Doppler target tracking as the original white Quantum 2 in premium black housing.    

Superior Collision Avoidance

Raymarine Quantum 2 Doppler target processing identifies and color codes moving radar contacts for instant recognition and reduced risk of collision. 

Quantum 2 MARPA mode provides an effective means of dangerous target tracking and is the same technology trusted by the United States Coast Guard.
