Survival Navigation

The compass is a great though ancient means of Navigation. Can't really improve upon it.

If you have an analog watch it can be a nav aid.

during the day you can point the hour hand at the direction of the sun and draw an imaginary line through the cent and between the 12 o'clock position and the hour hand. This is the North South line. Spending on your location, north or south hemisphere which end is north.

Remember to have your watch set to local real time. Not day light savings time.
