HD Color radomes pack big radar features into a small enclosure. They support bird mode, dual-range scanning, high speed scanning and much more.


Marine Radar Key Features - Doppler Target Tracking | Raymarine - A Brand by FLIR

Doppler Target Tracking

Available exclusively on Quantum 2 radomes, doppler allows the radar to instantly detect targets in motion and display them in a unique color palette. Inbound targets are red while outbound targets are green for improved awareness in high traffic situations.

Marine Radar Key Features - Target True Trails | Raymarine - A Brand by FLIR

Target True Trails Display

Shows the historical path taken by moving targets on the radar scope. The live target will display in its primary color, while its path or wake will remain visible behind it for a selectable period. This allows you to more easily see targets in motion and determine their direction of travel across the radar scope.

Marine Radar Key Features - AIS Integration | Raymarine - A Brand by FLIR

AIS Integration

Lets you see the icons of other vessels detected with your Automatic Identification System receiver on your radar scope. To use this feature, you will need to have a suitable AIS receiver or transceiver connected to your multifunction display.

NEW Magnum Radar - Real Time Heading Updates | Raymarine - A Brand by FLIR

Stabilized PPI Display

Allows the radar Plan Position Indicator (PPI) or scope to update in real-time even as the heading of the boat is changing. This gives you a smooth, accurate plot of all radar contacts when changing course or maneuvering, without having to wait for the radar scanner to sweep through a full rotation. Stabilized PPI requires the presence of a heading sensor like the Raymarine EV1or an Evolution Autopilot System.

Marine Radar Key Features - MARPA Target Tracking | Raymarine - A Brand by FLIR

MARPA Target Tracking

MARPA is a collision avoidance feature which allows your radar to acquire and track targets of interest. Targets can be acquired manually or automatically (on some systems.) After acquiring the target, the radar will calculate the target’s course, speed, closest point of approach (CPA) and time to CPA. On-screen symbology shows you the target’s direction and speed. Visible and audible cues warn you of developing dangerous situations.

Marine Radar Key Features - AutoGST Technology | Raymarine - A Brand by FLIR

AutoGST™ Technology

Refers to Raymarine’s adaptive transmitter and receiver. It automatically adjusts the Gain, Sea Clutter and Tuning for true hands-off operation. Auto GST continuously monitors the environment and adjusts these setting automatically for the best picture under all conditions.

Marine Radar Key Features - Radar Overlay on Chart | Raymarine - A Brand by FLIR

Radar Overlay on Chart

Lets you see the live radar image as a semi-transparent layer on your navigation chart. This allows you to confirm the positions of navigation aids, other vessels, obstacles and landmass by comparing them to charted objects. Radar overlay is also very useful to boaters new to radar and looking to get comfortable interpreting the radar returns.

Marine Radar Key Features - Timed Transmit Mode | Raymarine - A Brand by FLIR

Timed Transmit Mode

Is a valuable power-saving feature for sailboats and electric boats. When enabled your radar scanner will automatically transmit at a selectable interval, and then go back into a low power standby mode. The reduces the overall duty-cycle of the radar while allowing you to maintain a long-range watch. The result is a significant savings of crucial battery power while underway.

Open-Array vs. Enclosed Radome Systems

Radome or Open Array - What's the difference?

Marine radar systems fall into two primary categories: Open-Array or Enclosed Radome Systems.

Open Array Marine Radar Systems | Raymarine - A Brand by FLIR

Open Array

Open-Array radar scanners are made of 2 parts. The radar pedestal houses the scanner’s electronics and drive mechanism. Atop the pedestal is mounted a radar antenna or array. Raymarine’s Magnum Open Array radar scanners consist of pedestals with 4kW or 12kW power output, and your choice of a 4-foot or 6-foot antenna array.

Open-array radars offer longer range capabilities than radome scanners. Open arrays offer enhanced details of shoreline and targets packed tightly together thanks to their larger antenna size. Open array scanners are also more sensitive to weak targets and targets at long range because of the increased gain from their large antennas.

Radome Marine Radar Systems | Raymarine - A Brand by FLIR

Enclosed Radome Scanners (Radomes)

Enclosed Radome Scanners contain many of the same components as their open-array cousins, but all the moving pieces are housed inside an enclosure called a radome. This arrangement is especially popular on sailing vessels and small boats where there is a chance of sails, rigging, lines, or fishing tackle getting wrapped in a spinning antenna. Radome scanners are compact and light weight, making them suitable for even the smallest boats.

Raymarine offers 2 series of radome radar scanners: Quantum radar systems use solid state CHIRP pulse compression technology to detect targets up to 24 miles away. Quantum also has excellent short-range detection for slow-speed fog navigation with its ability to see objects as close as 18-feet to the scanner.

HD Color scanners offer many of the same features as the Magnum open-array, in a smaller package. HD Color systems can see out to 48 miles and offer features like bird mode, dual-range scan, high speed scan and more.

Radar Scanner Systems

Raymarine offers 3 different types of marine radar systems: Quantum radomes, HD Color radomes, and Magnum Open-Arrays. Use the following table for quick comparisons between model lines. Please refer to each product’s individual specifications for exact values.
