The FS2 is easy to use and easy to understand. You can manually set your target heart rate zone and then get feedback as to when you are in that target zone with the Polar FS2 visual and audible alarms. While exercising, you will constantly see your heart rate and can use the FS2 as a stopwatch. The Polar FS2 has time of day and the date and weekday indicator for after your workout. After your workout, you can also check your exercise duration, maximum heart rate of total exercise and the average heart rate of your workout.
