I am training for the upcoming XC ski season by roller-skiing. During the last few workouts, my VA3 is only registering a heart rate in the high 70's during the first 10 minutes of the workout. If I manually check my pulse, it's actually 140-150.
The VA3 does seem to eventually regain its accuracy. This problem has been happening only since the last update.
Any ideas on what's happening here?
