Garmin Vivoactive 3 HR accuracy

Hodders · 24 Feb 2021 at 18:06

Does anybody else's Garmin under-read HR at the start of activity? Mine does. I stopped to take my HR manually at 4min in and it was about 160 to 165. My vivoactive 3 was reading 120. After about 8 minutes it was fine. Wierd... Blue line is what I reckon it should have been saying.

Any tips?

I'll try the 'sweat' idea. Cheers. Although it reads fine during the day.....

Cycling, so cadence shouldn't be an issue.

Really helpful replies, cheers all.

Tried a slightly tighter strap and a bit of spit on the back of my wrist before I started - worked a lot better... Cheers....
