PRE OWNED JRC JLR-7700 JRC JLR-7700 MARINE GPS

The JRC JLR-7700 (Display unit NWZ-4570) features a high-contrast 5.7-inch monochrome LCD that provides essential navigational data with professional-grade accuracy. It is specifically engineered to meet the stringent performance standards set by the IMO for GPS equipment. The system is prized for its ability to maintain a consistent position fix even in areas with poor satellite geometry or environmental interference.

The unit is designed for 24/7 bridge operation, serving as a primary data source for the ship's AIS, Radar, and ECDIS. Its interface is straightforward and tactical, allowing officers to quickly save waypoints, plan routes, or access the dedicated Man Overboard (MOB) function. The JLR-7700 is a cornerstone for vessels that prioritize long-term equipment lifespan and ease of integration within a JRC-equipped bridge.
