How to use a compass
The red needle will always point towards the north pole the blue needle will point to the opposit. So if you line it up with the N then you can identify which way you are facing. The compass will also be marked with an E for east an S for south and a W for west. In between will be a NW a NE a SW and a SE these will tell you all directions for you to get around. Using a compass is very uncommon but if you go sailing it might help you get to land in the north.
