The Suunto Spartan Collection is the newest line-up of multisport watches, building on the success of Suunto’s Ambit series. After training for several years first with a Suunto Ambit 2, then an Ambit 3 Sport, and finally an Ambit 3 Vertical, I was pretty excited to get my hands on their top-of-the-line Suunto Spartan Ultra recently so I could put some of the new navigation features to the test.
