I carried a small pocket compass when I was on business trips in Japan.

Helped me to take the correct train when one might get onto a train on the opposite side of the platform which would go the exact wrong direction. Highly useful when you mostly can't read the signs.

Also used the compass to figure out what direction the correct exit from the massive train station would take me where I wanted to go (i.e. back to the hotel).


I use a compass to pre-calculate how to position my tent for maximum morning shade at a motorcycle rally.

Compasses, and maps, are wonderful!
