I recently saw this on another forum as quoted from a SAS survival manual. I am looking for confirmation on the accuracy and utility of this

Quote:

Take a gunsight or a stick- point at star. Wait 15 min or so.

If:

Star goes up-- it is in the east
Star goes down- it is in the west

Star goes left-- it is in the north
Star goes right- it is in the south

Reverse for Southern Hemisphere.
