For sporting or high-intensity activities a heart rate monitor needs to be paired with CALERA to ensure accuracy.

The heart rate signal delivers crucial metrics that help CORE recognise fast changes in intensity (for example a cyclist who reaches the summit, then descends).

CALERA can be paired to most existing (current generation) heart rate monitors.

This is the CardioSport TP5 Heart Rate Monitor which has proven to be a reliable and robust solution that is compatible with CALERA.

The CardioSport Heart Rate monitor supports both ANT+ and BLE and is compatible with most sports hardware and software.

The CardioSport TP5 comes with the strap that can be adjusted to fit. It also comes with a battery included which is replaceable and rated for 900+ hours of use.

Please note, the CALERA device can be purchased separately and is not included. The photos are for demonstration.
