What customers say
The Raymarine Quantum 2 Doppler Radar earns high praise primarily for its superior situational awareness. Users value the TargetShift feature, which color codes targets as safe or dangerous, significantly aiding collision avoidance in poor visibility. The solid state design is appreciated for its instant power up and very low energy use, which is excellent for battery dependent vessels. While the initial cost is premium, the safety improvements provided by the Doppler overlay are consistently seen as justifying the expense. Installation is generally simple due to the lightweight dome and easy connectivity. Overall, the radar delivers exceptional short range clarity and game changing utility for serious boaters.
Know before you buy
The Doppler technology automatically identifies moving targets and color-codes them based on whether they are approaching or moving away from your vessel. This allows you to instantly distinguish between potential collision threats and stationary objects like buoys or landmasses.
No, the Quantum 2 is a standalone radome antenna. It is designed to integrate with your existing compatible Raymarine multifunction display via Wi-Fi or a wired Ethernet connection.
Yes, the Quantum 2 supports Wi-Fi connectivity, which simplifies installation by eliminating the need to run a data cable to your display. However, you will still need to provide a 12V or 24V power connection to the unit.
The Quantum 2 has a maximum range of 24 nautical miles. Its CHIRP pulse compression technology ensures that you maintain high-resolution target detection for both close-range navigation and longer-range situational awareness.
Yes, its lightweight 18-inch radome design is ideal for smaller vessels where space and weight are concerns. Despite its compact size, it offers professional-grade features like automatic ARPA tracking and a rugged IPX6-rated housing.
The Quantum 2 features a quick-startup design, meaning it is ready to transmit almost immediately after being powered on. This ensures you have instant situational awareness as soon as you head out on the water.
