FLIR - RAYMARINE E70498 M Quantum 2 Q24D Doppler

The Raymarine Quantum 2 Q24D is the benchmark for immediate situational awareness on coastal vessels. Its primary advantage is Doppler target tracking, which instantly color-codes moving threats—red for incoming, green for retreating—significantly reducing the cognitive load during night navigation or heavy fog. Leveraging solid-state technology, it eliminates the warm-up time of traditional magnetrons and provides excellent target separation at close range. The option for wireless Wi-Fi data connection simplifies installation by removing the need to snake RayNet cables through difficult spars or masts.

The trade-off is a 24 nautical mile maximum range, which is modest compared to high-output open arrays, and users are essentially locked into the Raymarine Lighthouse 3 ecosystem to utilize the Doppler features. While it isn’t designed for long-range offshore bird-finding, the low power consumption and critical safety insights it provides at standard cruising ranges make it an exceptional value. Given its price point, the Quantum 2 remains a definitive "buy" for any navigator prioritizing collision avoidance and rapid deployment over extreme long-distance detection.
