The Polar AXN 500 sports watch is ideal when the terrain is tough, when the weather gets rough, and when you need accurate bearings to guide you. This altimeter/heart rate monitor shows your current altitude reading with graphical trend curve and your vertical progress. Check your pace down the mountain or up the rock with the Vertical speed feature. The barometer allows you to track the changing weather, while the compass keeps you on course. The AXN 500 comes with the Polar WearLink 31 coded transmitter. The OwnIndex feature tests your fitness level, so you can set a baseline and track your improvements. The OwnCal feature monitors your energy expenditure (calories) so you know when to refuel.
