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.Features:Designed GPS core delivers enhanced position fixing accuracyBright 4.2" high-resolution color LCD (700cd)Storage for 3,000 track points, 10,000 waypoints and 100 routesSBAS capable for better positioning calculationsShare and display position information on networked equipment such as a Fish Finder, Sonar, Radar, etc.NMEA0180 input port receives data from Fish Finder, Radar, etc.7 display modes available, including 2 user-customizable modesDisplays position data in Loran TD'sUSB port for importing/exporting waypoints and routes; Upload/download data in GPX format for easy transfer to TZtouch/TZtouch2"Click-In" hanger for easy mounting/dismounting and uses no knobs - also perfect for overhead mountsMulti-language ready : English, French, Spanish, Chinese, Vietnamese, Malay, Indonesian and ThaiThe GP39 includes antenna (GPA017), powe

Does the job. Particularly nice to see that it offers all three legacy versions of the NEMA standard for output via user option. I needed this to interface to an older (fussy) stabilizer circuit. Worked like a charm. Only gripe is that the "destination" function is limited to next waypoint when following a route. Don't understand this as I'm always interested in ETA for the final waypoint when on a cruise. Otherwise excellent quality.

Sure dozens of cheaper ones that have better specs. But for the rock solid reliability especially as a stand alone this unit has my trust. 100% easy install, big buttons and never a glitch. Long after those garmins and raymarines are failed the furuno will be shouting out latlon. If it had built in WiFi and n2k, well that would be tops

I had a GP31 from Furuno which worked perfectly for 20+ years. Alas, in April 2019 it stopped giving accurate data due to the GPS rollover (week data from the satellites is transmitted in a 10 bit word, which only handles 20 years of weeks). I bought a GP39 which operates fine, once you get it installed.The mount, though, is sub-par. It will work great if bolted to a table, but you can't mount the GPS display on a vertical bulkhead; if you do the display is angled 45 degrees down and is unreadable. I Dremel-ed away some plastic which helps, but it still won't angle parallel to the bulkhead. It's about 20 degrees down. The mount is also cheap. And, with the Dremel-ed mount angled 20 degrees down the cables get crunched.It also draws much more power than the GP31. The spec says 0.7 amps. I'm measuring about half that, which is still twice the GP31's current consumption.There's no manual provided, just 4 pages of inscrutable info. I did finally find a manual on-line. It's pretty good, but is lacking important info, for example, about the I/O Setup page.Finally, it doesn't send the NMEA sentences about which satellites it's watching, so my AIS can't display that info. That was also true of the GP31. And good luck trying to program the thing to transmit the right NMEA data! It's an undocumented trial and error process.

14x9x7 are the shipping *box* dimensions.The item itself: base is 7"Lx3.25"W. 7" tall.(Just received; have not yet installed/tested operation.)

My husband needed this so he could see his TD's and the speed is very accurate this machine work wonderfully on our shrimp boat.

Just don’t make them any better. My third one in 20 yearsMay be cheaper but none better.
