Despite the emergence of modern navigation aids, the relevance of compasses has not come to naught. Sometimes we really need this assistant, because he has a number of advantages. For example, he does not sit down at the most inopportune moment, so he will not let us down in the field.
How to learn to use a compass?
In fact, learning how to use this device is not difficult at all. To do this, you will need a map of the terrain and, in fact, a compass. And before learning how to use a compass, we need to understand how it is arranged by its principle of action.
The appearance of the compasses can vary significantly, but they are all designed in the same way. The compass has a magnetic needle that points to the poles of the Earth.
The arrow moves along the scale of divisions, which is divided into 360º. Also on the compass panel, for convenient orientation, there are aligned lines parallel to the arrow.
To start using the compass, lay it on your palm and lift it to your chest. It is so right to keep the compass during the journey. When you need to check the card, put it on a flat and firm surface, lay the compass on top. After that, take a look at the magnetic needle.
If you need to go north, turn the compass until the direction of the arrow coincides with the corresponding mark on the scale. Similarly, you can find all the other directions of motion.
Remember that the difference between the northern geographic pole (the top point of the map) and the northern magnetic pole can differ by several degrees because of the non-uniform magnetic field of the Earth.
You need to take into account even the slightest deviation, because you can go absolutely not where you planned to go. To do this, you need to know in advance the magnetic declination in the area where you will travel. Correct the course, subtracting or adding to it the required number of degrees.
Before you go on a trip, practice well at home so that you can know how to use the compass in your apartment without hesitation.
How to use the compass in the forest?
When moving through the forest, you need to determine from time to time the direction by rotating the compass. Rotate it until the direction arrow coincides with the direction itself, taking into account the magnetic variations of the terrain.
Continue in the specified direction, holding the compass correctly. While checking with it, be careful not to move the panel of divisions. To follow in the right direction, look afar and designate yourself a landmark - a tree, a pillar. After reaching the landmark, determine the next and continue to move.
If the forest is very dense and visibility is limited, divide up with a fellow traveler. Ask him to go in the direction indicated by the compass, if necessary, correct it. When he leaves the field of view, shout and stop him.
How to use the digital compass in the phone?
Modern phones are equipped with many useful features. Including, GPS-navigation . This allows you to determine the location of the object with an accuracy of several meters,
The principle of the compass in the phone is quite simple. It determines the angle of rotation of the mobile phone , giving the data to the screen. It works on the basis of the GPS-navigator, from which the signal goes to the sensor in the phone. The digital compass reads the information and provides it to the user.
The data from the digital compass is visible on the GPS-navigator's map. To determine the sides of the world, you can additionally install special applications on your phone. With such a compass, you can easily navigate in an unfamiliar city, finding the right objects.
