Smallest, Lightest GPS Unit in the World! If you love technology and just have to own the latest and greatest, here's the watch -- or rather, wrist-top computer -- for you. This unit combines GPS functionality with an altimeter, barometer, compass, and thermometer, and yes, it also tells time! Its usability in any environment makes this a perfect instrument for outdoor professionals and serious enthusiasts. With the X9 you can preplan and save your route, direct your way en route, display speed, distance, remaining distance and ETA. It will record your tracks so you can always find your way back. Store locations of interest ahead of time, or as you come upon them along the way. Use the included software and your computer to analyze data, plot routes and waypoints, import scanned paper maps, follow weather trends and more. After the trek, play an animated version on the computer screen for analysis, attach video clips, or share your adventure with other enthusiasts. So much more -- an amazing feat of technology!
