The 2003 line of Sports Instruments heart rate monitors represents a new approach to how we look at heart rate information. While everyone following a heart rate training regimen worked towards specific zones and percentages of maximum or threshold heart rate, most heart rate monitors only display raw heart rate data. Leaving the user to still figure out how an otherwise meaningless number actually related to their personal training goals.

All new Sports Instruments Fit and Pro heart rate watches feature automatically programmed training zones and allow the user to view their percentage of heart rate at any time. This single, simple change in design philosophy dramatically simplifies and enhances the usability of a heart rate monitor for everyone from the beginner to the professional athlete.

Of course, all ECG monitors receive their signals from Sports Instruments ultra thin IndePadª transmitter with a user-replaceable battery.
