Unfortunately, Suunto simply does not manage to integrate a stable and reliable heart rate measurement. Applying all the user tips does not help. The measurements fluctuate between imaginary maximum values and total failure.
If you value acceptable HR measurement without a chest strap, the watch is the wrong choice. Otherwise, it wouldn't be that bad. It's a shame that Suunto can't manage that. On the contrary: since the latest update, it got even worse.
