Polar's FT4 monitors your workouts to help you get the most out of your valuable training time. It records a whole suite of heart rate information that's displayed on Polar's easy-to-use, intuitive interface to ensure that you're maximizing your efforts. Plus, the FT4 even records calories burned, so you'll know just how hard that last training session was. And, its comfortable chest strap is uniquely coded to prevent interference from other devices and to give you the most accurate training info possible.
