MAKE SURE THE COMPASS IS FLAT WHEN USING IT:
Your compass must be flat to detect magnetic north correctly. For example, place your compass in the palm of your hand. When using a map, place the compass on the map on a flat surface.
WHAT IF YOUR COMPASS LOSES ITS BEARINGS?
Use your compass away from magnetic sources or it could lose its bearings: high-voltage power lines, mobile phones, keys, metal objects, etc. Even another compass might affect the direction!
SIMPLE BUT RELIABLE.
It isn’t a toy! It is as reliable as a high-end compass. It helps you orient yourself from a macro standpoint. The difference lies in the additional features: the size of the dial, readability and speed.
