Raymarine Quantum 2 Q24D Radar Doppler w/10M Power & Data Cables Product Description

Enhance Your Boating Safety with Advanced Doppler Technology

Navigating busy harbors, foggy inlets, or nighttime waters demands radar that doesn't just detect— it interprets. The Raymarine Quantum 2 Q24D stands out by blending CHIRP pulse compression with Doppler processing, delivering crystal-clear target separation from as close as 18 feet out to 24 nautical miles. Imagine threading through a fleet of fishing boats or dodging unlit obstacles; this radar paints a dynamic picture, color-coding threats in real time for instinctive decisions.

Boaters often face clutter from waves, rain, or nearby vessels cluttering traditional screens. Quantum 2's superior interference rejection cuts through that noise, while its lightweight 18-inch dome (just over 21 inches in diameter and 8 inches high) mounts effortlessly without straining your vessel's structure. Drawing minimal power—peaking at 17 watts—it's ideal for sailboats or battery-powered day cruisers, extending your time on the water without recharge worries.

How Doppler Processing Transforms Radar Awareness

Doppler isn't gimmickry; it's physics harnessed for safety. Radar pulses bounce back from targets, but moving objects shift the echo's frequency—like the siren pitch change of an approaching ambulance. Quantum 2 detects these micro-shifts instantly:

• Red for inbound: Approaching vessels or hazards closing in, demanding immediate action.
• Green for outbound: Receding traffic you can monitor casually.

This at-a-glance intel shines in high-traffic zones, where scanning echoes manually risks missing a crossing ferry. Pair it with TrueTrails, and you see ghostly wakes trailing contacts, revealing speed and direction history for predictive maneuvering—perfect for overtaking or avoiding head-on paths.

Safety Sector: Your Invisible Guardian Ahead

While Doppler excels at motion, stationary killers like rocks, buoys, or moored boats lurk silently. Enter Safety Sector: a 15-degree forward cone extending roughly 200 meters, auto-highlighting these static threats in red as if they're charging toward you. No manual tweaks needed; it activates seamlessly, bridging the gap between motion and menace.

For coastal cruisers or fishing in shallows, this feature proves invaluable, spotlighting pilings or debris that echosounder alone might miss. Combine with automatic target acquisition—set zones for audible alerts on intruders—and you've got Coast Guard-grade vigilance without the complexity.

Effortless Tracking with MARPA and ARPA

Manual plotting? Ancient history. Quantum 2's Doppler-boosted MARPA (Manual Radar Plotting Aid) and fully automatic ARPA lock onto up to 10 targets, computing course, speed, closest point of approach (CPA), and time to CPA. No guard zones required; it anticipates collisions, flashing warnings and beeps to pull your eyes from the helm.

Real-world edge: In a regatta or commercial waterway, it distinguishes a tack from a straight-line rammer, letting you focus on sail trim or throttle instead of guesswork.

Installation Simplicity Meets Rugged Reliability

Upgrade without headaches—Quantum 2 reuses bolt patterns from legacy Raymarine scanners. Connect via slim data cable, Wi-Fi to multifunction displays, or hardwired for redundancy. IPX6 waterproofing shrugs off tropical downpours, with a -10°C to +55°C operating range suiting diverse climates. Winds to 100 knots? It spins at 24 RPM unfazed.

Beamwidth (4.9° horizontal, 20° vertical) ensures sharp, clutter-free returns. Horizontal polarization slices sea state, while low emissions let you mount near crew areas safely. Power from 12-24V sources, it idles at 7W, sleeps at 2W via Wi-Fi—sailors' dream for off-grid adventures.

Ideal for Every Hull: From Ribs to Cruisers

Sailors love the pulse compression for punching through canvas shadows; powerboaters appreciate zero-warmup instant-on for quick exits. Short-range wizards detect pots or swimmers in zero-vis fog, long-range scouts spot squalls early. Weighing half traditional magnetrons, it's a game-changer for trailerables or flybridges.

Tip: Layer with AIS for labeled traffic, or sonar for submerged views—Quantum 2 elevates the stack without dominating it.

How Doppler Radar Works:

• Microwave energy waves are bounced off of a distant target, just like conventional radar.
• Moving targets send back echoes whose frequencies shift upward or downward from what was originally transmitted.
• For inbound targets, the frequency increases as the leading edge of the returning echoes are received more frequently as the target’s range decreases.
• For outbound targets, the frequency drops as the returning echoes spread out as its range increases.
• Doppler radars are engineered to detect these small shifts in wave frequency, and use them to classify moving radar targets.

Doppler Target Processing

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.

• Inbound targets are colored red
• Outbound targets are colored green

Color coded targets make it simple to pick out moving traffic from other stationary targets like land, navigation aids or stopped/anchored vessels.

Quantum 2 Safety Sector

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:

• Buoys
• Exposed Hazard (rocks, pilings, etc...)
• Slow moving, low visibility vessels
• Quantum 2's Safety Sector spreads 15° from the bow to a distance of approximately 200m

NOTE: The safety sector is not visible on the display. Quantum 2 automatically processes and highlights targets within this region in red.

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 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.

The Quantum 2 with Doppler truly sets the standard for on the water safety and collision avoidance.

The Raymarine Quantum 2 Q24D Doppler radar with target tracking function provides a safer navigation experience through a simplified installation method, and its weight is only half of the competitors' radar domes. The 24NM range of Quantum 2 is very suitable for picking up and tracking long-distance targets. Low power consumption and excellent short-range target separation capabilities make this radar an ideal choice for small motorboats and sailboats. By adding Raymarine Raynet to the Raynet coupler and increasing the connection between Raynet and Raynet cable, the connected 10m data cable can be expanded. The Doppler technology used in the Quantum 2 Q24D has been specially adjusted to detect the frequency shift of radar echoes from moving and stationary targets. Quantum 2 actually color-codes the moving targets to determine which objects are moving toward or away from the container. You can even set boundary areas, and if one of the targets enters these areas, you will receive an alert to notify you. This is a great feature if you plan to travel overnight. Quantum 2 has Raymarine's "True Trails" target history display, which allows you to view the historical "wake up" behind each moving object. This makes it very simple to determine the direction of travel for these targets, allowing you to make informed decisions to maneuver your boat. The Raymarine Quantum 2 Q24D Doppler 18-inch radar will add a lot of colors to the compatible Raymarine MFD.
