Compare watch and hearth rate monitor data

Hi all. I have a Forerunner 645 and I started using a hrm pro a couple of weeks ago. Data from chest monitor sounds a bit out of my usual performance. How can I compare data from watch and from the band? Thanks

Search the Connect IQ store. There are several apps there that allow you record heart rate from the onboard optical sensor and an external sensor and save it to the FIT file for later comparison.

if you’ve been using WHR for your activities then you can expect to see a difference. The strap will be giving you more accurate information that you should now use.
