The FURUNO GP39 GPS Navigator provides accurate and reliable position fixing, thanks to a 12-channel GPS receiver combined with integrated SBAS (WAAS/EGNOS/MSAS) technology. The GP39 has various display modes, including Plotter, Highway, Steering, NAV data, and Satellite monitor, as well as 2 user-customizable display modes, allowing you to select which data you want displayed on its 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 GP39 can be networked with a fish finder, sonar, radar or other navigation equipment for feeding highly accurate navigation data. The GP39 receives the TLL (Target Latitude/Longitude) sentence from networked fish finders or sonars and can display the received information, allowing you to easily mark fish school locations.• Type: Tube Mount• Screen Size: 4.2 Inch LCD• Point Of Interest: 10000 Waypoints• Bluetooth Compatible: No With Antenna Unit With 10 Meter Length Cable, Plastic Bag 12 To 24 Volt DC IP55 Rating Waterproof Receiver/IP56 Rating Waterproof Antenna | Furuno GP39 GPS Receiver in Blue
