Designed for performance cyclists, the Edge 500 GPS-enabled bike computer is small and lightweight. It tracks speed, distance, GPS position and elevation, so you can get the most from your training and racing. Edge 500 is compatible with ANT+ heart rate monitors, speed/cadence sensors and third-party ANT+ power meters. It also features advanced calorie computation based on heart rate information for more accuracy. Edge 500 uses a high-sensitivity GPS receiver with HotFix satellite prediction to calculate your position faster. It also has temperature readings and a start notice that warns you if the timer is not going when you begin moving. Edge 500 features a low-profile, quarter-turn mount that fits on your bike's stem or handlebar. Once your ride is complete, upload the workout to Garmin Connect for detailed analysis and mapping.
