GPS Watches: Monitor Your Performance

There are currently at least six manufacturers of GPS watches: Nike, Tech4o, Timex, Garmin, Polar, and Suunto. Casio used to have one, but it’s been discontinued. Garmin has a line of eight GPS watches. They are marketed as speed and distance systems for athletes – they do not provide location information.

The speed and distance systems are composed of two parts: a GPS receiver and a watch that are wirelessly connected by a radio signal. The GPS receiver can be worn on the arm or clipped to a belt. However, the following GPS watches do provide location information. One of these GPS watches is reviewed here.

The Casio also can be connected to a PC for data exchange with the included software. With all it does, it is a good value – its price new was about $200.00.
