2. Polar H10 XS - S

The Polar H10 heart rate sensor is a strap that transmits the heart rate to the smartphone or sports watch with particular accuracy in real time. As wearing a sports watch is not permitted in some sports, such as swimming, or data transmission is not guaranteed, the sensor has an integrated memory for individual training sessions. This means you don't have to carry your smartphone or sports watch with you. The data can then be easily transferred. The training data can be viewed via the training app (Polar Beat). The improved electrodes provide an optimum signal for measuring the heart rate. Additional non-slip silicone points and a soft textile strap ensure a high level of wearing comfort. The closing mechanism also ensures close contact with the skin.

7. Suunto Smart Heart Rate Belt

The Suunto Smart heart rate belt provides accurate heart rate data while remaining comfortable to wear. The strap's efficiency is unbeatable, especially for sports where hand movements interfere with wrist-based heart rate measurement, and allows heart rate measurement even when the watch is worn over the sleeve or attached to the bike handlebars, or when the watch is not worn at all during a workout.

The Suunto Smart heart rate belt has an R-R memory that is used when the watch is not in range of the Bluetooth smart radio. This is super for team sports, for example, as it allows recordings to be made without wearing the watch. The memory function is supported by the Suunto 3, 5, 9, Spartan, Ambit3 and Traverse watches.

Avid cyclists, team athletes, martial artists, climbers, swimmers, water sports enthusiasts, triathletes, ski mountaineers, cross-country skiers, inline skaters and gym fans can get the most benefit from using the Suunto Smart heart rate strap.

The Suunto Smart heart rate strap is also a great companion for the free Sports Tracker app with Android, iOS and Watch OS devices.
