Raymarine Q24D Quantum 2 Black Radar Dome without Cables
Model: E70498-BIntroducing 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.
Raymarine Quantum 2 Doppler target processing readily identifies and color codes moving radar contacts for instant recognition and reduced risk of collision.
Quantum 2’s exclusive Safety Sector feature provides the maximum level of visibility to dangerous targets in the path of your vessel (both mobile and stationary).
Doppler-enabled MARPA provides an effortless means of dangerous target tracking by eliminating the need to setup guard zones. Raymarine MARPA target tracking is the same technology trusted by the United States Coast Guard.
Doppler radar is tuned specifically to detect the radar echo frequency shift returned by moving vs. stationary targets.
Quantum 2 then uniquely color codes moving targets to indicate whether they are getting closer, or moving away.
Doppler does an excellent job of bringing attention to moving targets, but it does downplay stationary targets, that can be equally as dangerous.
Safety Sector provides equal attention to these imminent threats by coloring them as inbound targets. Potential targets include:
The Quantum 2 also features fully automatic target acquisition and tracking. Configure custom safety or alarm zones and be alerted to new radar contacts entering the zone. Quantum 2 can begin tracking those contacts automatically, calculating their course, speed, closest point of approach and more. You’ll be alerted to dangerous contacts with audible alerts and easy to understand on-screen graphics.
Quantum 2 also features Raymarine’s new True Trails target history display. The True Trails features enables you to see a historical "wake" behind every moving contact. This additional information makes it even easier to interpret the motion of other vessels, and make smart maneuvering decisions to pass safely.
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.
