Well of course I have my mom's phone number memorized, but how does that help if I've locked my phone in the car in the middle of nowhere? I am NOT saying that's an appropriate use of the SOS function- I actually think this function has the potential to cause a lot of ridiculous false alarms... Look at all the problems national parks are having with people setting off their SPOT alarms because they are thirsty.

When I initially read about the SOS function before I ordered the Bia I thought "great- I won't have to carry my phone anymore." But now having thought about it, I should still carry my phone, and there's really no added benefit of the SOS signal. It's a nice idea, but seems a little gimicky.
I guess I didn't clearly explain that I do a lot of my running alone in moderately remote areas where there are variable weather conditions, wild animals, and occasionally unruly humans. I always tell at least two people where I'm going and when I'll be back, then I let them know when I'm back safely.
