Ideal for the gym, the Kinetik heart rate monitor measures the heart rate in three ways, current, max and average, as well as functions such as a basic watch, built-in alarm, stopwatch, backlight and calorie counter. The heart rate data is transmitted by the included chest strap. All the heart rate information (current, maximum and average rate) is all displayed on the large backlit LCD screen for ease of use while walking, running or during other exercises. A maximum heart rate set by the user will sound an alarm if the heart rate exceeds it, allowing you to keep track of your exercise and avoid over-working the heart. Includes bike clip for easy attachment. For any questions or help with this product, please contact Kinetik Wellbeing. Wrist monitor. Batteries required 1 x button cell (included).
