Heart Rate Strap vs Wrist Heart Rate

[Greg Frampton]

I’ve tried finding this answer online and have t found a definitive answer. If I’m wearing a Suunto Heart Rate Chest Strap, do I need to disconnect the wrist HR monitor on a Suunto Race? Which will be the default, the chest strap or the wrist? And activities where I used to burn 600 kcals with just a cheat strap and the app or my old Ambit 2R, are now measuring maybe 400 kcals. Why such a big difference?

@Greg-Frampton the watch will always default to an external monitor, if paired. If not paired, or not in reach, it defaults to optical heart rate.
