Отзыв о Датчик ЧСС POLAR H10: с поддержкой Bluetooth, 🏋️ черный, M-XXL - продвинутая точность для мониторинга сердечного ритма от Gloria Ruiz ᠌

In general, more is needed when training with ragged pulses. measurement and return to the pulse zone is faster. If the run is uniform, it makes no sense to take it. Different pros: Compatible with Garmin watches, universal size, washable tape, measurement speed is higher than with wrist watches Got cons: It is discharged if not disconnected from the tape even on one riveting. There is no understanding on which of the protocols the connection is better.
