Could someone with both the 645 and HRM-tri please confirm if it allows to record HR during Cardio without wearing the watch, only the strap? I usually take the watch of during practice, as it gets in the way. But still want HR recorded through the HRM-tri.
This feature should be added in a future software update, since Garmin has added it to their older and much cheaper running watch Forerunner 235.
I sent Garmin an email asking them to consider adding the feature for this very reason...people might as well email it to them as a suggestion; the more people asking for it the better IMO.
I'm in the same situation here with the 245 Music. I'd like to buy a HRM-Tri and use it for gym/workouts where I can't wear the watch, to track my HR and training effect. *NOT* for swimming.
It looks like this works on the 235, but probably not on the 245. I've asked Garmin support.
