Polar H10 Fix

A Polar H10 heart rate monitor, two o-rings, and an HR monitor strap.

Although I’m currently running without using technology such as HR monitors, I remembered that I meant to write a post about a quick fix for issues I used to have, and have seen others reporting, with Polar H10 heart rate monitors. It relates to random drops in heart rate during a run, as seen towards the end of this long steady run;

When the strap was new it worked perfectly for a while, but then I’d start to see these dropouts in every run after a warm up. In an effort to resolve it I had tried replacing the battery, but would end up having to replace the strap, only for the same problem to return within 3 to 6 months. Others have said that this is what they do, claiming that the strap is a consumable item that needs regularly replacing, but that seems wasteful and doesn’t sit well with me.

Various YouTube channels have praised the previous version of the cream faced watch, and having bought the current version and liked it, when I saw a black-faced version available I knew I had to add that too.
