you need
• - compass;
• - a small steel object;
• - straight line or splinter.
Guide
1
First check whether a compass works.To do this, take a steel object (this may be keys, scissors, etc.).Place the compass on a level surface and remove the mounting direction, if any.The arrow should indicate the blue end of the north.Take the prepared steel object and setting the opposite end of the arrow pointing to the north, keep it along the housing.The arrow should point to the steel object.Going quarter turn (in the conventional clock face it will be 15 minutes), remove the object.The arrow should go to the original position, that is to point to the north.
2
Before calculating azimuth and be sure to check that there are no obje
cts around the compass of iron, current-carrying conductors or permanent magnets, which may adversely affect the measurements.Then decide the scale interval of the compass, which measures the degree to which the arrow is rotated.Take two neighbors of digital values ​​and divide them by the number of divisions of the difference between them.
3
Set the compass horizontally and remove the stopper from the arrows.After some hesitation, the blue end of the arrow should point to the north.Set the scale of the compass so that its pointer coincides with the direction of the north arrow.This point corresponds to the zero azimuth have.
4
You can then navigate the terrain.Put in the direction of the object to which the application orientation of thin and elongated object.This can be a twig, line, splinter, match and others. The only limitation - the subject should not be made of iron or an alloy of the metal, otherwise the needle just starts to show on this subject, making it difficult to calculate the azimuth well.
5
Calculate the angle between the object and the direction of the north.To do this, count the number of divisions between them and multiply that number by the scale value.
