Raymarine RD424HD 4Kw 24" HD Dome With 10M Cable

The Raymarine RD424HD 4Kw 24" HD Dome with 10M Cable is the radar workhorse serious anglers and commercial operators depend on when conditions deteriorate and visibility vanishes. Whether you're running offshore in thick fog, navigating tight coastal channels at night, or reading weather patterns before a storm rolls in, this 24-inch dome radar delivers the situational awareness that keeps your vessel and crew safe. Built to withstand salt spray, constant vibration, and years of demanding saltwater use, the RD424HD transforms your helm into an information center—not just showing you what's out there, but helping you understand what's coming.

At 4 kilowatts of transmit power, the Raymarine RD424HD cuts through rain and clutter with precision that smaller units simply cannot match. The 24-inch dome houses a rotating antenna array that sweeps 360 degrees, building high-resolution HD imagery that updates multiple times per minute—fast enough to track moving weather cells, other vessels, and structural hazards in real time. The 10-meter cable allows flexible mast-top or hardtop mounting while keeping control head installations below deck or at the helm, reducing weight aloft and simplifying integration with existing Raymarine navigation systems. The sealed dome design and stainless fasteners ensure corrosion resistance in the harshest marine environment.

Commercial fishing operations, charter boats, and serious cruisers benefit most from the RD424HD's reliability and range—typically detecting large vessels beyond 48 nautical miles and weather systems even further. Installation requires a clear, elevated mounting point (typically the hardtop or mast) and integration with a compatible Raymarine multifunction display or navigation system; the 10-meter cable length accommodates most helm layouts from tower to transom. This radar pairs seamlessly with Raymarine's gPS/chartplotter ecosystem, feeding target tracking and weather overlay data directly to your screen. Weight of 50 pounds is substantial but manageable for most modern sport-fishing and commercial vessels, and the investment in proven, professional-grade radar pays dividends every time you leave the dock.
