I have Foreunner 965 recently bought. whe i do floor climbing, the heart rate capture lags behind and doesn’t bit capture the actual elevated heart rate. i run up the stairs and my heart rate will be well above 140 but the watch will be showing only 108-110. i have tried to check and cross check this many times.
but sadly watch heart rate monitor is behaving erratically and recording g false values
pl look into it
