With high power output and superior sensitivity the RD424 radome scanner is the perfect choice for coastal cruisers, offshore fishermen and serious offshore adventurers.

The RD424's sleek 25.7" radome houses our most powerful enclosed radar system with 4kW of transmit power and a 24" high performance antenna array. The RD424 further benefits from Raymarine's exclusive low-noise front end technology and class-leading 8 pulse-width / PRF transmitter provide optimum performance at all ranges, under any weather conditions.

When the fog rolls in or the weather turns nasty, the RD424's high power transmitter and high-gain antenna/receiver make short work of tracking other vessels, identifying navigation aids, and providing other critical information for safe passage making.

The RD424 radome is compatible with all Raymarine C-Series Classic and E-Series Multifunction Displays, and includes a 15 meter display interconnect cable.
