Very accurate HR tracking.
5 Stars
Very accurate HR tracking.
I had used charge 2 which was ok in terms of hr accuracy. It was usable when running or stair climbing, but nowhere near useful in strength training or HIIT.Then got versa for a couple of weeks which was better than charge 2 but again was lacking when it came to HR tracking in HIIT.So looked around, chest straps were not for me. So got this to give it a try and so far has been very very good. The attached pic is interval training on rowing. Such a great reflection of what I was doing. It did very well with weights and core work too.It is very slightly uncomfortable on my forearm but not too bad.
Thank you for your feedback
