Raymarine’s HD Color radome scanners combine the power and clarity of HD Color signal processing with an ultra-compact scanner suitable for all types of vessels. These radomes offer a 256-color radar display and the clearest, most lifelike presentation available from any radome scanner.

The RD424HD and RD418HD feature the same adaptive digital receiver technology found in Raymarine open array antennas. By adjusting automatically to changing environmental and sea conditions, the HD Color radomes provide crisp, accurate contact echoes at short ranges, as well as outstanding long-range performance up to 48 nautical miles.

      Comments about Raymarine RD418HD Color Radome:

      I use radar all day off the Oregon coast. Navigating a tricky bar in the fog is impossible without radar, and overlaying synched data on top of my chartplotter makes it much easier. Offshore, I can locate other fishing boats, large bird flocks and obstructions while navigating and fishing. With multiple displays, you can overlay radar data and view it separately at the same time. I won't go offshore without it.
