If the declination is West (W), subtract the indicated value from the value you
have just read. If the declination is East (E), add the variation to the value you
have just read. The position of magnetic north (NM) also changes with time, but
these variations are negligible over a time span of a few years.

A compass is a precision instrument.
Do not drop it.
•
The operation of the compass varies with the temperature. The oil that slows
the needle may congeal or liquefy depending on the ambient temperature. In
order to preserve its performance capabilities, protect the compass from
extreme temperatures (e.g. by keeping it under a garment).
•
The compass requires a few seconds to stabilize. Do not take the reading into
account until the needle has stabilized completely.
•
To use this compass, you need to have a map. Opt for a map with a scale
available on the compass. For optimal use, also bring along a wooden pencil
and an eraser.
