Suggested Use & Compatibility

Recommended for running, cycling, triathlon and outdoor training when you want navigation and more detailed performance data than an entry-level running watch provides. Set up Polar Flow, download maps and transfer routes before heading somewhere without reliable mobile coverage. Use compatible Bluetooth accessories where needed. Polar's wrist ECG, oxygen estimates and skin-temperature measurements provide wellbeing/training context only, and cannot diagnose or exclude medical conditions. Select battery modes according to GPS accuracy and anticipated session length.
