If we talk about heart rate monitors, then it is a lightweight and slim training computer with an integrated GPS. The watch is compatible with the Polar Bluetooth Smart heart rate sensors and offers a 24/7 activity measurement as well as a daily activity goal. WORKOUTSGEAR has identified and compared the best heart rate monitors.
Pulse watches without chest strap from the current test may have different measuring functions. The basic operating principle is based on the measurement of heart rate, which is usually done directly on the wrist. You wear the heart rate monitor as well as a normal wristwatch on the wrist, where it sits safely without disturbing.
