A GPS is a great tool for staying found. Even a cheap GPS like my old Garmin Geko will point the way back to where you parked the car. A mapping GPS like my Garmin 60CSx will present a map of what's around you and put your location in perspective. Really useful tools, calling in the cavalry is not required if you stay found.
If you leave a GPS on continuously, you do run the risk of running down the batteries which is why:
1) You don't leave it running continuously, you turn it on, determine the course to your destination and then turn it off. Use a mag compass to follow that course; and,
2) Carry spare batteries, just in case.
As for the couple who got lost in this incident and the authorities who seemingly failed to respond, I have little to say that isn't fairly self evident to the readers of this board.
