This article will explore the features, benefits, specifications, and common FAQs about the Raymarine Quantum 2 Q24D, making it your go-to resource whether you’re an experienced mariner or a boat owner looking to upgrade your navigation equipment.

What is the Raymarine QUANTUM 2 Q24D Doppler Radar?

The Raymarine Quantum 2 Q24D is a compact, lightweight, and power-efficient 18-inch radome radar featuring Doppler target tracking. Built for recreational and light commercial vessels, the radar is equipped with advanced target discrimination and enhanced situational awareness technology.

The radar’s CHIRP pulse compression and Doppler processing work in harmony to offer crisp, high-resolution images and intuitive color-coded targets for safer and smarter navigation.

Key Features of the Raymarine Quantum 2 Q24D

1. Doppler Radar Technology

Doppler radar technology enhances situational awareness by distinguishing moving targets. It color-codes moving targets — red for approaching, green for receding — helping boaters immediately recognize potential collision risks.

2. CHIRP Pulse Compression

The Quantum 2 Q24D uses CHIRP (Compressed High-Intensity Radiated Pulse), which sends longer pulses for increased energy on targets and compresses the signal return to sharpen radar resolution. This means better detection of small objects even in cluttered environments.

3. Range and Precision

• Detection range: 18 feet to 24 nautical miles

• High resolution ensures you can spot small boats, buoys, and even birds

• Precise target separation in both short- and long-range applications

4. True Trails™ and Target Tracking

The radar features True Trails, which show a historical “wake” of moving objects, making it easier to determine direction and speed. Combine that with MARPA (Mini Automatic Radar Plotting Aid) and Doppler target tracking, and you get real-time situational assessment.

5. Solid-State Design

No magnetron means:

• Instant startup

• Lower power consumption (just 17 watts transmit)

• Safer operation in confined spaces

6. Lightweight and Easy Installation

Weighing just 12.5 lbs (5.6 kg), the Quantum 2 Q24D is 60% lighter than traditional radomes. It supports both wired and Wi-Fi connections, making it an easy retrofit for most vessels.

Technical Specifications

Benefits of Using the Quantum 2 Q24D Doppler Radar

1. Improved Collision Avoidance

Doppler target color-coding gives immediate visual cues on nearby vessels’ direction of travel, helping you quickly spot and avoid threats.

2. Enhanced Navigation in Poor Visibility

Whether it’s night, fog, or rain, the Q24D delivers sharp radar images, making it indispensable for safe navigation under any weather condition.

3. Energy Efficiency

Its solid-state build drastically reduces power consumption. Ideal for smaller boats with limited electrical capacity.

4. Fast Wake-Up and Ready Time

No magnetron warm-up means instant-on radar, reducing wait time and allowing you to act quickly in urgent situations.

5. Compact Footprint

Easily mountable on sailboats, center consoles, and cabin cruisers — its small size doesn’t sacrifice performance.

6. Seamless Raymarine Integration

The Q24D integrates effortlessly with Raymarine Axiom and Element displays, giving you access to advanced overlays, route planning, and more.

Comparing Quantum 2 Q24D vs. Traditional Magnetron Radars

Use Cases and Applications

1. Recreational Boating

Perfect for weekend cruisers and anglers, the Quantum 2 Q24D helps navigate busy waterways and anchorages.

2. Sailing Yachts

Its lightweight and low power draw make it ideal for sailboats where performance must be balanced with energy conservation.

3. Commercial and Charter Boats

Fishing charters, tour operators, and workboats benefit from the radar’s long-range visibility and quick response.

4. Nighttime and Offshore Cruising

Boaters navigating at night or across open waters will appreciate the Q24D’s True Trails and MARPA functionality, especially in remote areas.
