I would appreciate your help - i would like to buy a watch for my husband's birthday and i am deciding between core and vector. As far as the design i prefer the CORE, cause i thing he won't be wearing it only in outdoors. But the thing is that it doesn't have the vertical speed function, apparently so i am wodering whether CORE has something to compensate it, e.g. if the logbook shows you the speed in real time as you are going up/down the mountain? I think this function is very useful
BTW are there any other reason why should i choose vector over core or vice versa?
Thank you very much
