Hi everyone, I've bought my Instinct for a few days. It is my first sport watch also first Garmin device. I see that when I moving my hand, the heart rate in my Instinct increase a lot, e.g when I stand it is around 75 and then I shake my hands continously or wash my face with my hands, it goes up to 100, even 110; of course I check my hr manually it doesn't change much. After that if I keep the hand that wears Instinct to un-moving, the hr in it drop quickly to around 75.
Do I need to worry about my Instinct? Is it broken or defective one?
