-
Important for the compass to work, there are a few things to consider when using it. Always keep the compass level so the north arrow and scale can rotate freely.
-
Do not use the compass near metal (e.g. metal bridge railings) or magnetic objects (e.g. mobile phones).
-
These things interfere with the correct reading because the north arrow is magnetic.
-
Accordingly, the compass can only work reliably outdoors and not indoors.
