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
The Polar FS1 heart rate monitor lets you set a manual target heart rate zone with visual and audible alarm. It give you your average heart rate during your exercise and elapsed exercise time. You can also wear it as a watch - it displays the time and it also has a stopwatch function. The extra large digits are appreciated. Water resistant up to 50 meters.
3. Polar F4 Heart Rate Monitor
The Polar F4 is designed for women and has a large number display. It includes calorie calculation, automatic and manual setting for heart zones, zone alarm when you get out-of-zone, and records your total time in zone. It displays heart rate both in number and percent of maximum. It has watch, alarm, and stopwatch, but no backlight.
