The best GPS EVER!!!
The Suunto Ambit Rocks! You can customize up to 8 screens for each activity by using Movescount. The GPS speed and distance is right on the money. I have mtn biked, run, skied, hiked all sorts of activities. In each case the Altimeter, GPS-Distance, Speed, HR, and other info has been 100% accurate. This watch will do everything for you except make your lunch!
