Raymarine Quantum Q24C 18" Radar with 10m Power Cable

Raymarine Quantum Q24C 18" Radar 

Raymarine Quantum Q24C 18" Radar represents the next generation of marine radar. Moving away from traditional magnetron technology, the Quantum utilises solid-state CHIRP Pulse Compression. This allows the scanner to identify small, weak targets even when they are positioned close to strong returns, giving you a level of detail and clarity previously unseen in a dome of this size.

At Morgan Marine, we recommend the Quantum for its remarkable efficiency. Weighing 50% less than traditional radars and drawing significantly less power (only 17 watts during transmission), it is the ideal choice for sailors looking to extend battery life and for powerboaters looking for a lightweight, high-performance solution.

This package includes a 10-metre power cable, providing plenty of length for a clean and professional installation on most masts, targa arches, or wheelhouse roofs.

Raymarine Quantum Q24C 18" Radar  Key Features

• Instant Awareness: No more waiting for your radar to "warm up." Solid-state technology means the Quantum is ready to transmit in seconds.
• Superior Target Detail: CHIRP technology ensures more energy reaches each target, resulting in exceptional imaging at both long ranges (up to 24nm) and extremely short ranges (down to 18 feet/6 metres).
• Easy Installation: With integrated Wi-Fi, you can connect the Quantum directly to any Raymarine LightHouse II or III powered MFD without running a data cable back to the helm.
• Safe & Efficient: The low-power transmitter emits safe levels of radiated emissions, meaning you can mount it almost anywhere on board without concern.
• CHIRP Pulse Compression: Delivers superior target recognition and sharp detail at all ranges.
• Exceptional Short-Range Performance: Clear imaging as close as 18 feet (6m) for navigating in tight channels or fog.
• Energy Efficient: Ultra-low power consumption (17W transmit / 7W standby) to preserve your vessel’s batteries.
• Lightweight Design: Weighs just 5.6kg—up to 50% lighter than comparable magnetron radars.
• Flexible Connectivity: Connect via the included 10m power cable and Wi-Fi, or use a wired RayNet Ethernet connection (data cable sold separately).
• Quick Start-Up: Ready to use in seconds with no warm-up period required.
• Simplified Mounting: Uses the same bolt pattern as previous generation Raymarine radomes, making it a perfect drop-in upgrade.
• Interference Rejection: Advanced technology eliminates noise and "blooming" from other radars nearby.

Raymarine Quantum Q24C 18" Radar  FAQs

What makes the Quantum Q24C different from traditional radars?

The Quantum Q24C uses solid-state CHIRP pulse compression technology. Unlike traditional magnetron radars that use a high-powered burst of energy, Quantum uses multiple compressed pulses to provide much higher resolution and "target separation." This means you can distinguish between a small buoy and a larger vessel even when they are very close together.

Does this radar require a long warm-up time?

No. One of the greatest benefits of solid-state technology is "Instant On" capability. While traditional radars can take 2–3 minutes to warm up, the Quantum is ready to transmit in seconds, providing immediate situational awareness the moment you need it.

How does the Quantum Q24C perform at short range?

It excels at short-range detection. Because it uses CHIRP technology rather than a high-power magnetron, it has a minimal "main bang" (the blind spot immediately around the boat). You can see targets as close as 18 feet (6 metres), which is invaluable for navigating tight harbours or foggy estuaries.

What is the maximum range of the Q24C?

The Quantum Q24C has a maximum range scale of 24 nautical miles. It is highly effective for tracking weather cells and landmasses at long distances, though performance at these ranges is always subject to the mounting height of the scanner and the height of the target.

Is it difficult to install if I’m upgrading from an older Raymarine radar?

Raymarine has made the upgrade path very simple. The Quantum Q24C uses the same bolt pattern as previous generations of Raymarine scanners. Additionally, if you already have an older radar cable in place, you can often use a Quantum adapter cable (sold separately) to repurpose your existing wiring, saving you the hassle of running new cables through the mast or arch.

Can I connect this radar wirelessly?

Yes. The Quantum Q24C features built-in Wi-Fi. It can connect directly to any Raymarine LightHouse-powered MFD (like the Axiom or Element series) without a data cable. You only need to provide 12V or 24V power to the dome using the included 10m power cable.

Is the Quantum Q24C energy-efficient?

Extremely. It is perfect for sailing vessels or boats where power management is a priority. It consumes only 17 Watts during transmission and 7 Watts on standby. In "Sleep Mode" (when connected via Wi-Fi), consumption drops to just 2 Watts.

Will it work with my existing Raymarine display?

The Q24C is compatible with:

• • Axiom Family: All models running LightHouse 3 or 4.
  • Element Series: Compatible via Wi-Fi only.
  • eS and gS Series: Running LightHouse 2 or 3.
  • a, c, e Series: Running LightHouse 2 (v19.03).

Please note: Older "Classic" C-Series or E-Series displays are not compatible as they only support analogue scanners.

Do I need a heading sensor for this radar?

While not strictly required for basic radar operation, we highly recommend a heading sensor (like the Raymarine EV-1). Adding heading data allows the radar to perform "MARPA" target tracking and enables "Radar Overlay," which places the radar image directly over your navigation chart for much easier interpretation of what you’re seeing on screen.

Is it safe to be near the radar while it’s transmitting?

Yes. Because the Quantum is a low-power solid-state device, its radiated emissions are significantly lower than a traditional magnetron radar. However, for best practice and safety, we always recommend mounting any radar scanner above head height.
