In the event that multiple same-information sensors are being employed (e.g. two speed sensors), the ELEMNT Bolt uses a quality of data hierarchy to determine which sensors will be used to gather data during your workout. In this scenario, if one sensor should fail, the ELEMNT Bolt will automatically switch to the next data source and continue data gathering. Manual selection of a duplicated data source is not available. For more information on pairing sensors, see the support article HERE.
