For your city, enter the average of the values of 2 nearby cities. 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 also changes with time, but these variations are negligible over a time span of a few years. 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. 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. A compass is a precision instrument. Do not drop it The operation of the compass varies with the temperature. The oil that slows USING THE COMPASS 3 operating modes are available for different orienteering needs : 1 - How do you take a bearing ?You know where you are and you have located your destination on the map (the angular direction in relation to the north)?You know where you are and you have taken the bearing (angular direction) to follow, 3 - How do you determine your position on the map ?You do not know where you are 21 EXPLANATION OF EACH OPERATING MODE 1 Determining an angular direction (Bearing) on a map 1 You are at point A and you want to go to point B. [. . . ] 340). 31 7 Place the map on a level surface and turn it so that the map's north is oriented towards the magnetic north indicated by the compass. 8 Find landmark R1 on the map. Orient the compass, starting at landmark R1 until the direction-of-travel arrow coincides with the bearing you measured before. Use one of the long edges of the compass to draw the measured bearing, passing through landmark R1. 32 9 Locate landmark R2, and then note the value of the bearing you have measured (B). 10 Turn the compass on the map (without moving the latter) until the direction-of-travel arrow of the compass lines up with bearing B.
