Furuno RD33 4.3 Color LCD Navigational Data Organizer

Description

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.

Key Features

• 4.3-inch color TFT LCD – Provides a compact screen for navigation and vessel data.
• 480 x 272 WQVGA resolution – Displays several data fields in a small instrument area.
• 700 cd/m² brightness – Helps with daytime viewing.
• NMEA 2000 and NMEA 0183 converter function – Allows data from different marine networks to be displayed.
• 0.2A maximum draw – Keeps the instrument’s electrical demand low.

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.

Compatibility

Confirmed connections include one NMEA 2000 Micro-C, one six-pin NMEA 0183 connection, and depth data through NMEA 2000 or NMEA 0183. The supplied information does not identify specific transducers, radar, autopilot, or third-party chartplotter systems. No named incompatible system was provided; verify required NMEA sentences and network power before installation.

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.
