Suggested Use & Compatibility

Recommended for structured endurance sessions and races where you want a detailed multisport watch plus a separate electrical heart-rate sensor. In Polar Flow, configure Vantage M3 sport profiles, mapping and route downloads before training. Moisten and wear the H10 Pro Strap beneath your chest muscles, then pair it with the watch. H10 has a replaceable battery while Vantage M3 charges by cable. Wrist ECG/SpO2/temperature are wellbeing insights, not diagnostic tests. Confirm watch colour and H10 strap size with North Sports before purchase.
