Take this it's dangerous out there! A wrist mounted GPS module from Garmin, that will help you navigate through the woods, just be sure to run if you hear the banjos.

Foretrex 601 is build to military standards for thermal shock and water resilience (MIL-STD-810G). It works with 3 main satellite systems (GPS, GLONASS, Galileo) for better coverage than just GPS. Battery life is longer than 48 hours and lasts 1 week in UltraTrac mode. The unit also shows your altitude, atmospheric pressure and heading (altimeter, barometer, compass).
