I have a Cardiosport Go 30 HRM. I find that no matter how tight I have the strap, once I get sweaty, the belt starts slipping and contact is lost. This is highly frustrating as (a) I have to keep trying to hitch it up under my bra as I run, which makes me look a berk, and (b) it ruins any attempts at trying to keep sensible records.
Does anyone have any hints on how to solve this problem? Is there a previous thread you could point me to? I've tried searching the forums, but not managed to find anything.
