Kevin R.wrote a review of Suunto Ambit Altimeter Watch on April 30, 2012
I have used many a Suunto products in diving and work and many Garmins with work. when it came time to find a new general GPS watch and one which I could use running I spent weeks reading reviews, gear testing friend's products and pursuing information. And It all led to the Ambit. There is not a finer GPS watch and Fitness watch out there. All the old issues with Suunto watches as far as poor reception and battery life are a thing of the past. I pick up the signal in the thickest wooded areas and never loose it on a trail run, and I even pick ip up indoors in all but the most interior rooms. Something some of my handheld units can't even claim. It handles any and all formats from MGRS to Lat/Long and UTM. It tracks perfectly with speed and distance and the ability to customize screen and info layout on Movescount.com is fantastic. The battery lasts longer then any other watch I have tested and providing the rare combination of full featured GPS and fitness device is amazing. Don't be misled, the Ambit will always be able to do heart rate, the only difference is the $550 model has the heart rate strap and the $500 allows you to buy it separately later. I highly recommend this to anyone, I use it biking, running, swimming, and the unique requirements of my job. This winter you can bet it will be on every backcountry trip and every climb all year with me.
