Sized for smaller athletes, the Polar F4 heart rate monitor helps keep fitness enthusiasts in the correct zone for optimized training benefit.

  • Visually follow the time in your target heart rate zone via the fitness bullets displayed
  • Set your heart rate limits and stay informed as to where you are within these zones with the innovative Zone Pointer and alarm system
  • OwnCal™ feature counts calories and fat burned based on your own effort level
  • Easy-to-read display and simple button access to functions make this monitor easy to use
  • Wireless receiver sends readouts that are ECG accurate
  • Accompanying lightweight Polar Transmitter is comfortable to wear in nearly any environment
  • Memory file stores average heart rate and total exercise time

Please note: The Polar F4 HRM is very small. It will fit the smallest of wrists. If you are not "petite" or you'd rather have a more mid-sized heart rate monitor you may wish to consider the Men's Polar F4 or the F6 as an alternative with a larger display.
