I have a Garmin (ANT+) HR device that I’ve used for a few years on my bike with a Garmin 1000 unit. It works fine in this environment. I’ve paired it on Zwift - I’m running Zwift on a Mac Book Air with an ANT+ dongle) and although I get a HR signal on Zwift, the actual HR itself is miles off (it’s too low). As an example Zwift might show my HR as 66bpm but if I measure it using the old fashioned method (fingers against neck) it’s closer to 145-150bpm.
Has anyone else come across this or found a way to solve it?
Garmin HR straps have a history of power spikes and or not reading HR for a period of time. Throw it out and buy something like a Tickr. I used to run Garmin straps and had problems. Things are much more reliable now that I’m using a Wahoo Tickr.
Thanks to both of you. The Garmin has a brand new battery so I don’t think it’s that. I’ll try doing a session with a Wahoo Tickr. Meanwhile I’ve sent Zwift the log files from my sessions to help them try to determine what the problem has is.
