The Q24D is designed to provide radar awareness from close range, with the supplied product specifications identifying an 18-foot (6-metre) minimum range. This is useful when radar coverage needs to include nearby targets as well as targets farther from the vessel. As with any marine radar, actual detection depends on installation, target characteristics, vessel conditions, weather, and the surrounding environment.
The 5.6 kg scanner has a listed diameter of 541.0 mm and height of 209.5 mm. The product information states that the Quantum 2 can utilize existing Raymarine scanner fixing points, which can simplify compatible upgrades. The scanner can be supplied without power or data cabling, or with 10-metre and 15-metre cabling options, depending on the configuration selected.
Before installation, confirm the required cable configuration, mounting pattern, display compatibility, power supply, and available installation space. The stated operating voltage range is 10.8–31.2 V DC, with either 12 V DC or 24 V DC listed as the nominal supply.
Power consumption is one of the notable specifications of the QUANTUM 2 Q24D. The supplied data lists a maximum transmit consumption of 17 W and standby consumption of 7 W. Sleep mode consumption is listed at 2 W for radars connected via Wi-Fi. These figures can be relevant when planning the electrical system of smaller boats or vessels where battery capacity and power management are important.
The Q24D is specified with IPX6 waterproofing and an operating temperature range of -10°C to 55°C. Storage temperature is listed as -25°C to 70°C, with the scanner to be stored upright and its underside vents kept unobstructed. Humidity is specified up to 95% at 35°C, while maximum wind speed is listed as 100 knots.
The Raymarine QUANTUM 2 Q24D is intended for a range of smaller-vessel applications, including sailboats, RIBs, and smaller powerboats. Its compact physical design, low power consumption, short-range detection capability, and flexible installation options make it suitable for vessels where space and electrical requirements need to be considered carefully.
When evaluating this Doppler marine radar, consider your vessel type, mounting location, existing Raymarine equipment, power system, cable requirements, and the type of radar coverage you need. Confirm all equipment and installation compatibility before purchase, particularly when replacing an existing scanner or using existing mounting points and cabling.
