First Use Experience

Our initial testing of the Raymarine Quantum 2 Q24D Doppler 18In Radar took place during several offshore passages, predominantly in conditions ranging from clear, sunny days to overcast skies with moderate sea states. We also deliberately navigated through a light fog bank to evaluate its performance in challenging visibility. Installation was relatively straightforward, integrating with our existing Raymarine MFD.

The system performed admirably under various conditions. Clear days showed excellent target definition for buoys, other vessels, and landmasses out to its maximum range. The Doppler display, with its color-coded targets indicating relative motion, was immediately intuitive and provided a significant boost to situational awareness. Navigating through the fog was where this unit truly shone, clearly differentiating between stationary and moving targets, and most importantly, highlighting inbound vessels with an almost uncanny accuracy.

Ease of use was surprisingly high. While the underlying technology is complex, the interface on the Raymarine MFD made it accessible. I didn’t need extensive time to adapt; the color coding and basic controls were self-explanatory. One minor surprise was the slight delay in target acquisition on very small, fast-moving craft immediately adjacent to our vessel, though this was quickly resolved by adjusting the radar’s gain and range settings.

Extended Use & Reliability

After several months of consistent use, spanning over 500 nautical miles, the Raymarine Quantum 2 Q24D Doppler 18In Radar has proven to be an exceptionally reliable piece of equipment. It’s been exposed to spray, occasional heavy rain, and fluctuating temperatures without any noticeable degradation in performance or visual defects. The unit still looks and operates as if it were new out of the box.

Durability has been excellent; there are no signs of cracks, stiffness in the housing, or any performance drop-offs. The Doppler processing remains crisp, and target separation is consistently good. Maintenance has been minimal, primarily consisting of occasional freshwater rinsing of the radome to remove salt spray. I’ve found no specific parts that require more than routine cleaning.

Compared to previous radar systems I’ve used, this Doppler-enabled unit significantly outperforms basic pulse radars, especially in its ability to track targets and alert to potential collisions. While it’s a more significant investment than a non-Doppler radar, the added safety and peace of mind it provides are, in my experience, well worth the price difference.
