Perfect for hikers, campers and skiers, the Garmin Foretrex 401 consists of a slim GPS navigator mounted on the wrist. You can keep track of your altitude, route and bearing with its high-sensitivity GPS receiver, electronic compass and barometric altimeter. Retracing your steps is equally easy. Garmin Connect enables you to track and analyze your data in one place. However, this smartwatch requires two AAA batteries, meaning that you just might need to carry along a spare in case they run out.
