Description of Suunto x9 Ladies and gentlemen, meet the Suunto X9, Suunto's long-awaited cross-sport GPS wristop computer. The Suunto X9 combines GPS functionality with an altimeter, barometer, compass, and thermometer ... all these instruments, packed into a single watch. Yes, the watch is bigger than your average watch, but it's packed with lots of great features. With the Suunto X9, you can plan routes at home with a map, and save them into your watch. When you're out in the field, your watch will advise you on which way to go, as well as tell you how fast you're moving, how far you've traveled, how far you still have to go, and when you'll be arriving at your destination. Mark a "home" position, and you'll be able to hit "find home" from anywhere and get the route and distance back. In addition, you can go adventuring without a route in mind, and use the Suunto X9 to keep track of your position, speed and distance. It will record your route, which you can save for later analysis, or use immediately to find your way back. Whenever you locate a place of interest, such as a great fishing spot, a campsite, or a stunning view, it's easy to save the coordinates into your watch, naming the location whatever you'd like. Overall, the Suunto X9 is the pinnacle of wristop navigational computers; it was made with hikers, mountaineers, trekkers, hunters, fishermen, and other outdoors-lovers in mind, and it shows.
