The X10 is the very latest from the Suunto laboratories, and its the lightest GPS-enabled wrist computer they have ever offered. With the X10, you can track your outdoor adventures in four dimensions, or use Suuntos Trek Manager software to pre-plan your route ahead of time. While youre out in the wilderness, use the barometer and compass to keep you headed in the right direction while you keep an eye on the weather. Record your speed, distance, and altitude along 500 GPS waypoints, then upload them to Google Earth at home to show your friends just how deep into uncharted territory you ventured. Improved GPS reception allows quicker fixes in deeper cover than ever before.
