FURUNO 66P3600 DS-50 Log Main Display Panel

The FURUNO 66P3600 DS-50 Log Main Display Panel is the primary user interface component for the Furuno DS-50 Doppler Speed Log system. This panel serves as the central point for mariners to view crucial speed and distance data, including speed over ground (SOG) and speed through water (STW), as well as total and trip distance logs. Designed for integration into a vessel’s bridge or console, it features a clear digital display and user-friendly controls for setting parameters, switching display modes, and accessing system information. As a key part of the DS-50 system, the 66P3600 panel ensures accurate and reliable monitoring of a vessel’s movement, essential for navigation, fuel efficiency, and safe operations.
