This portable satellite tracker can give you a vital line of communication when you want it, and can connect with emergency assistance if you need it.
Using satellite technology, the tracker works where cell phones don't.
Two subscription services are available. For $99 per year, you get a 24/7 link to emergency service, and can also send pre-programmed personal messages to up to 10 contacts via e-mail or phone text messaging.
For an additional $49 a year, friends and family can track your trip progress via Google Maps.
