Product details

Raymarine - QUANTUM 2

Raymarine's QUANTUM 2 CHIRP pulse compression radar with doppler target identification technology provides you with extra safety on both long and short distances.
Due to the special processing of Doppler radar data, it is possible to display moving targets in color on the display.

Easily Identify Dangerous Targets

Raymarine Quantum 2 Doppler target processing readily identifies and color codes moving radar contacts for instant recognition and reduced risk of collision.

Superior Collision Avoidance

Quantum 2 MARPA mode provides an effective means of dangerous target tracking. Raymarine MARPA target tracking is the same technology trusted by the United States Coast Guard.

Key Features:

Doppler moving target display allows for superior situational awareness at-a-glance
Fully automatic ARPA target tracking, along with manual MARPA mode
Adjustable TrueTrails target history shows the motion history of moving contacts
CHIRP Pulse Compression detects contacts as close as 18-feet for zero-visibility navigation
24-mile range for early detection of traffic, navigation aids, landfall and weather
Immediate awareness – Quantum starts up and is ready to go in seconds
Superior interference rejection eliminates noise from other radars
Simplified installation with Wi-Fi or thin wire network connectivity
Easy upgrade – Quantum 2 fits the same bolt pattern as other Raymarine scanners
Lightweight and easy to install – Quantum weighs up to 50% less than comparable magnetron radars
Safe emissions – mount Quantum anywhere onboard
Low power consumption for extended battery life under sail

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 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.

Fully Automatic Target Acquisition and Tracking

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 new 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.

High delivery costs, without explanation

Correspondence on the high delivery costs

Why are shipping costs of €19.95 charged for a package that is 60x60x30cm and lighter than 5kg?
The package came via UPS, not a freight forwarder. I have also received larger and heavier packages from SVB for the standard shipping cost of €6.95.
Can you please check the cost?
Sincerely B

Dear Mr B
Thank you very much for your email.
The costs of 19.95€ are the costs for the delivery of bulky goods, which are delivered by UPS. Bulky goods are not only measured on the basis of size or weight, but also if certain items (in your case the radar antenna) have a specific marking that require bulky goods to be shipped.
The identification of certain delivery conditions of some articles can also be seen next to the product in the online shop.
For questions we are at your disposal.
Best regards
SVB

Hello,
why is the radar antenna to be marked as bulky goods?
I didn't find that in your answer.
Sincerely B

Dear Mr B
Thank you very much for your email.
If you want precise reasons for this, please contact UPS.
For questions we are at your disposal.
Sincerely / Best regards

Technical question

William L. | Jan 22, 2021

If you want to use the Doppler and MARPA features of this radar do you need an EV1 or EV2 add-on?

Answer from manufacturer

Bernd G. | Jan 25, 2021

An electronic compass is necessary for full functionality at all times. An EV-1 can be used for this purpose. However, it does not necessarily have to be this compass.

General question

Craig B. | Jun 20, 2019

Does this radar need a Raymarine MFD or can it talk directly to an iPad / Laptop ?

Answer

Martin H. | Jun 20, 2019

The radar cannot talk directly to an iPad, you need to interface it either with WiFi or network cable to the compatible MFD. You can then interface the entire system with an iPad via various Raymarine Apps
