Enhance Your Boating Safety with Advanced Doppler Technology

Navigating busy waterways or foggy conditions demands radar that doesn't just detect— it interprets. The Raymarine Quantum 2 Q24D stands out by blending CHIRP pulse compression with Doppler processing, instantly spotlighting vessels closing in on your path while fading out those heading away. Picture threading through a crowded marina at dusk: red alerts flash for inbound traffic, green for outbound, giving you split-second decisions without sifting through clutter.

This solid-state radar excels where traditional systems falter, offering crystal-clear short-range views down to 18 feet. Boaters praise its ability to cut through rain and sea clutter, revealing hazards like unlit buoys or slow-drifting debris that could spell trouble.

Master Collision Avoidance Like a Pro

Doppler isn't gimmicky—it's physics at work. Radar pulses bounce back from targets, but moving ones shift frequency: higher for approaching (Doppler effect in action), lower for receding. Quantum 2 tunes into these micro-shifts, color-coding targets for intuitive awareness. Inbound threats glow red, outbound green, while stationary objects stay neutral until they matter.

The game-changer? Safety Sector. This invisible 15-degree forward cone out to 200 meters treats static dangers—like rocks, pilings, or sluggish boats—as inbound reds. No more overlooking a moored yacht in your track. Pair it with automatic MARPA tracking: up to 10 targets locked, with course, speed, and closest approach calculated automatically. No guard zones needed; just set custom alarm zones for audible pings on new intruders.

TrueTrails: See the Past to Predict the Future

Ever wonder where that ferry was headed last minute? TrueTrails wakes trail every moving contact, adjustable in length and fade. It's like a motion replay, helping you gauge turns, speeds, and intentions. In a regatta or shipping lane, this visual history turns guesswork into strategy, letting you anticipate crossings safely.

Built for Real-World Boating Demands

Weighing far less than older magnetron radars, this 18-inch dome slips onto existing mounts with minimal hassle. Fire it up in seconds—no lengthy warm-ups. Low draw (under 20W peak) suits battery-powered sails or tenders, and IPX6 sealing shrugs off pounding waves. Rotate at 24 RPM with a tight 4.9-degree horizontal beam for sharp target separation up to 24 nautical miles.

Interference rejection is top-tier, muting nearby radars so you focus on what counts. Connect via slim wires or Wi-Fi to multifunction displays, keeping your helm clean. Ideal for sailboats, RIBs, and compact powerboats chasing adventure without bulk.

Zero-visibility heroics with 18-foot minimum detection

Installation Simplicity Meets Rugged Reliability

Skip the yard overhaul: bolts match legacy Raymarine patterns, and 15-meter cables reach most setups. Power from 12-24V sources, and you're scanning in under 30 minutes. Vent it properly for longevity, and it'll handle -10°C chills to +55°C swelters. Boaters report years of flawless performance with basic care, underscoring why it's a staple for coastal cruisers and bluewater explorers alike.

Pro tip: Pair with AIS for layered intel—Doppler handles motion, AIS identities—creating an unbeatable safety net.

Why Boaters Choose Quantum 2 Q24D

Beyond specs, it's about confidence. In high-traffic zones like the Solent or Chesapeake, Doppler slashes reaction times. Short-range punch reveals pots and markers in fog; long-range eyes track squalls. Lightweight design eases trailering, low power extends offshore legs. It's not just radar—it's your vigilant watchmate, turning perilous passages into routine sails.

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 adding Raynet to the Raynet cable, the connected 15m data cable can be extended. The Doppler technology used in Quantum 2 Q24D (T70417) 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.
