If you're going out of the "normal" area, consider bringing along a cheap, but functional GPS. Helicopter services have GPS units onboard and if you can give them a lat/long they can fly right to you. This would be not needed for places that have an actual landline. Consider adding clamps to the kit if you're going someplace really remote. They can be used to do what those trauma nurses did and they do not get tired.
