4.2" GPS NAVIGATOR Model GP-39

Highly accurate position fixing GPS navigator with clear color LCD

The FURUNO GPS navigator GP-39 provides accurate and reliable position fixing, thanks to a 12-channel GPS receiver combined with integrated SBAS (WAAS/EGNOS/MSAS) technology.
The GP-39 has various display modes (Plotter, Highway, Steering, NAV data, Satellite monitor and 2 user customizable modes) on the 4.2" color LCD. Up to 3,000 points of ship track, 10,000 waypoints and 100 routes (each with up to 30 waypoints) can be stored. The waypoint and route data can be exported/imported via a USB flash drive or signal converter.
The GP-39 can be networked with a fish finder, sonar, radar or other navigation equipment for feeding highly accurate navigation data.
