Currently I run with a FR225, a foot pod and a regular HRM strap. I am looking to purchase the 645M once it arrives, however I want to make sure I can fully utilize all the features associated with the watch.
I know the HRM, and foot pod will work with the 645, however instead of getting the DP I was hoping to decrease some of the accessories I have attached to my body.
If I drop the foot pod and HRM, would the HRM3 and HRM-Run cover what both what the two pieces already cover, or would I be better off just paying the $70 for the DP and having 3 items attached to my body?
Which is newer, the HRM3-Run, or the HRM-Run?
