HRM for two people AND measures distance?

Sytera

My husband gave me the go ahead on a HRM. However, he'd like me to get one that we can both use and that measures distance. He is 6' 200 lbs and I am 5'5" 116 lbs. Do they make them with seperate profiles? Or are we going to have to both buy one? I was about to get the Polar FT4 when he decided we should share. What other one should I look at for him/me/us? Thanks!
