Sorry to revive an old thread of mine…but I’ve solved all my HR strap issues and thought might be useful for others. I’ve always had issues with a couple of HR straps/monitors cutting out after 15 mins or so and giving very poor inconsistent readings - hence why In was going to buy a new strap.
I bought some electrode gel (few quid on amazon) to put on the strap after seeing it recommended a few places but that didn’t help.
HOWEVER I had the brain wave to put a small dot of electrode gel on the press studs that connect the strap to the monitor to improve the connection and FIXED! Totally consistent strong good HR readings every time regardless if running, riding indoors or riding outdoors - works perfect. Whenever I wear the HR monitor, just small dot of electrode gel on the press studs and away I go!
Hope it helps others with any HR monitor issues!
