Polar FS1 heart rate monitor is currently the most basic of all Polar heart rate monitors. It is the entry level monitor in Polar's fitness monitor series (F- and FS- series). It is intended for general use and fitness training.
Here are the main features about the Polar FS1 heart rate monitor. It has:
Continuous Heart Rate Monitoring
Manual Setting of Heart Rate Training Zone with Audio and Visual Alarm
Duration of Exercise Session (using its Stop Watch)
Average Heart Rate of Exercise Session
Basic Time Keeping - can set the time only, but not day of the week or date
Wireless heart rate monitor composed of an analogue chest strap transmitter and a wrist watch receiver
This heart rate monitor is pretty basic. But it does the job if:
you are new to heart rate monitoring, or
your requirements are modest and you just want to use something simple, or
you have a limited budget.
Bear in mind that you can't exactly use it as a ordinary digital watch since you can't set the day of the week (Tues, Wed etc) or the date. The lack of a backlight may also be an issue for you if you happen to do a lot of exercise in the dark. Its suggested retail price is $69.95.
