[Gear] GPS Tracking Device [Guide's Pick] Spot GPS [Description] 
Spot GPS devices have been the standard, but the DeLorme inReach has been increasingly popular, as you can send and receive text messages with it. We carry a tracking device on every trip, but you might consider bringing one as well. Again- consider how you will keep it powered over the course of your expedition.
