I love my Garmin 235, except for the optical HR.
My HR often locks onto my cadence (at around 180 SPM) and it is very, very annoying. It is essentially the only reason I upgraded from the 620 to have optical HR. It seems to happen most frequently when I start to run downhill after a long uphill climb. I'd say 4 out of 5 runs have a significant spike where it locks onto cadence. Sometimes for over 80% of the run.
Are there any threads on here which have tips in how to stop my watch from locking onto my cadence? I have tried wearing my watch tighter, but it doesn't seem to work.
I don't have hairy arms, which I see has been a problem for some.
I have the 4.10 software.
Here are some examples:

Thanks all
