Heart Rate issue?

Hi Everyone,

I am facing unsolved issues with the HR reading on my FR265 since i bought it 2 years ago, still not solved by Garmin despite countless updates.

(It uses HR monitor gen 4, and I understood that FR 570 is using more recent HR monitor gen 5.)

As i am considering moving to the Fr 570, does anyone has/had any issue with HR readings on this model?

Thanks in advance.
