While I do like my Garmin 510, I hate hate HATE the chest strap. It's uncomfy, sticky, and either feels too tight or like it's slipping. I find myself wearing it less and less, especially on hot, humid days.

Has anyone here tried using a wrist band sensor with there Garmin? Is there even such a thing? If so, did you notice any accuracy problems?

Just looking for an alternative to that chest strap.
