I always choose to carry a satellite communicator on any big expedition, and it’s just as much for the peace of mind of my family as it is for my safety. Being gone for a month at a time in the backcountry can take a toll on parents or friends back home, wondering if everything is all right. Getting a little nightly message saying you’re fine does wonders to quell those fears. And of course, these devices could save your life if you’re severely hurt or stranded in the wilderness and need a rescue.
