dc45-6a flap compass with scale

【Usage Method】

1. Ensure that the actual terrain aligns with the map direction.
2. Find two targets that can be seen on the map.
3. Align the compass's direction line (or the long side) toward one of the target objects.
4. Find the circle that matches the arrow and the pointer (North).
5. Do not change the direction of the circle and place it in the northern position on the map.
The tip of the long edge of the compass aligns with the target on the map.
7. Draw a straight line from the arrowhead of the circle to the extension of the magnetic north line.
8. Continue the same method for another target. The intersection of the two lines is the current location.
Use a compass to find the direction to go:
1. Align the straight line connecting the current position and the destination with the compass bearing (long edge).
2. The arrow pointing to the circle is parallel to the magnetic north line (the arrow is located at the top part of the map).
3. Remove the compass from the map and hold it in front of your body.
4. Twist your body until the arrow and the pointer overlap.
5. Overlap the line direction to equal the target direction of the map.

【注意事项】
The compass must be placed horizontally, and to avoid the compass from being misaligned, it should be kept at a certain distance from magnetic objects. The reference data is as follows:
1. More than 10 meters away from the barbed wire.
2. More than 55 meters away from high-voltage lines;
3、离汽车或飞机>20米；
4. Stay away from objects with strong magnets, such as various magnets, external loudspeakers > 10 meters;
5. Objects with weaker magnetic properties, such as magnetic snaps, are greater than 0.5 meters away.
