Never leave home without it - Suunto Ambit2 Sapphire GPS Watch

I've had my Suunto Ambit2 for over 2 years now. I purchased it to use while training for my first marathon. Anytime I do anything outdoors, the Ambit2 is always with me...running, mountain biking, backpacking, fishing, mountain climbing. This thing has literally taken a lickin' and kept on tickin.' I was initially worried about battery life, but I've never had it die on me on multi-day backpacking trips. If I had to name one negative, it is a little bulky, but so is every other gps watch out there (at least when I purchased it two years ago).
