More Information

The H803 reads your pulse at the forearm using a photodiode and a dual-beam array, which picks up heart rate changes in real time. There is no chest strap to put on, so it is easy to wear for rides, runs and indoor sessions.

When your heart rate reaches the warning value you set, the armband vibrates. This is easier to notice mid-ride than an LED alert and helps you control training intensity. The case uses IML construction, so it is wear-resistant, scratch-resistant and resists fading, and a separate side button switches it on and off (press for 2 seconds).

It connects over standard ANT+ and Bluetooth, so it works with Magene and other mainstream bike computers, sports watches, smart trainers and training apps.
