I think the big difference here is my wife is usually out on her own bike, with her own Spot and if we split up, we think it's best to get a text message giving an indication of where the other person is. We don't mind getting multiple text messages. And tracking kills batteries much faster. I can go a season on a set of Lithium AA or AAAs. But to each his own. I think tracking's useless and a waste of money, but that doesn't mean you have to.
