The Edge 500 can track GPS position, speed, distance, time, elevation, climb and descent. It also has a barometric altimeter to pinpoint changes in elevation. Its high-sensitivity GPS receiver with HotFix also allows it to display temperature readings and changes in time zones.
GPS isn't its only game. When paired with a Garmin heart rate monitor it can track micro changes in a user's heart rate and can calculate the number of calories burned. The Edge 500 retails for $US250 and $US350 with the bundled heart rate monitor. [Garmin]
