Lifespan of Garmin heart monitor
My Garmin chest strap heart monitor started getting flaky on recent rides, the reported heart rate doesn't match my Forerunner or my expected heart rate. This has been easier to notice when riding Zwift.
I changed the batteries in August, so it shouldn't be low batteries. Then I realized I've had the monitor since Aug 2013 (purchased with Edge 510) - I'd estimate nearly 2,000 hours of use. I don't expect these will last forever, thoughts?
