Polar AXN500 Heart Rate Monitor

When the terrain is tough, when the weather turns, when you need accurate bearings to guide you, the new Polar AXN500 Outdoor Computer will get you there and back again. Superior comfort of the WearLink coded transmitter, and a sleek stainless steel design.

	Altimeter - Shows your current altitude reading with graphical trend curve and your vertical progress. The Altimeter allows you to identify your current altitude and to determine altitude-related conditions. It will also aid in pinpointing your position on a map and help you select an appropriate route. Using the Altimeter, you will learn how much you can ascend or descend per day, and how fast you can ascend or descend in current weather conditions.
	Vertical Speed - Shows ascent and descent rate indicating how fast you have gone vertically up or down. You can utilize this information to keep track of your performance or to keep your speed constant (e.g. to save energy on a long hike or other outdoor activity).
	Barometer - Monitor weather changes with barometric pressure and temperature reading. Use the Barometer to measure sea level or absolute barometric pressure. Sea level pressure represents the unit’s estimate of absolute pressure corrected to sea level (as reported from a weather station or airport). Absolute barometric pressure is true atmospheric pressure at current altitude and conditions.
	Compass - For navigating and monitoring the right direction. A digital compass is included in select Polar Outdoor Computer models. The direction value is given as a cardinal point, as well as in degrees. For example, when heading east, the letter E, the value in degrees (90) and three pointers indicating your north will appear on your wrist unit display.
	Polar Fitness Test™ with OwnIndex® - Measures your fitness level in 5 minutes. A fitness test that measures your aerobic/cardiovascular fitness at rest in just five minutes. The result, Polar OwnIndex, predicts your maximal oxygen uptake (VO2max). With the Polar Fitness Test you can measure your aerobic fitness by yourself, automatically and without any exertion. No other equipment other than a heart rate monitor is needed. The Polar Fitness Test is as accurate in predicting the VO2maxas any sub-maximal fitness test.
