Furuno RD33 4.3 Color LCD Navigational Data Organizer

The Furuno RD-33 is a compact navigational data display for boats that need depth, speed, environmental, and engine information in a small instrument panel. Its 4.3-inch color screen can combine data from NMEA 2000 and NMEA 0183 sources, making it useful on mixed-age boats where not every sensor speaks the same protocol. It is not a chartplotter or sonar processor.

The 480 x 272 display runs at 700 cd/m², giving it useful daylight visibility in a cockpit or pilothouse. The unit draws up to 0.2A and fits a 90 x 90mm cutout, so it is easy to add without consuming much panel space. Depth arrives through NMEA 2000 or NMEA 0183, depending on the connected equipment. The built-in converter function helps bring those data sources together on one screen.

Who Is This For?

This Furuno data display suits fishing boats, cruisers, and workboats that need depth and vessel information in a dedicated gauge. It is not ideal for buyers seeking charting, radar, or fishfinding images; it displays incoming data rather than creating charts or sonar returns.

Warranty & Support

Furuno provides a 2-year standard warranty. The supplied specifications do not state warranty exclusions or service procedures.

The RD-33 is the flexible choice when a boat has both NMEA 2000 and older NMEA 0183 equipment to monitor. Its trade-off is the absence of charts and imaging sonar. Choose it as a compact data repeater for depth, speed, and vessel information, not as the primary navigation display.
