A heart rate monitor is an excellent fitness tool, allowing you to work out within your chosen heart rate zone. Extras beyond the heart rate reading include stopwatch, exercise timer, clock, settable heart zones with alarm, and backlight. Check whether you can change the battery yourself or must send it to the factory. Decide what you want and shop for the best value.

1. Timex Road Trainer Heart Rate Monitor

The Timex Road Trainer uses a chest strap sensor for maximum accuracy. The wrist monitor is a full-featured Timex Ironman sports watch. You can view your heart rate with the time of day and while using the chronograph and timer. It has a minimum and maximum heart rate alert, five pre-set heart rate zones and a customizable zone. I like the large number display and a night light. Perhaps because I've used Ironman watches in the past, I find the Timex more intuitive and I find it easier to navigate the displays and menus than I do with Polar heart rate monitor products. The watch is large, but you could easily wear it and use it as a sports watch, independent of its heart rate monitor function.

2. Polar FS1 Heart Rate Monitor
