How to use a compass

Perhaps the most successful invention is a Chinese compass, which has been used for centuries to determine the right path.How to use a compass, they know everything, without exception, sailors, hikers, pilots and even tourists.

This device landmark.It should be noted that emit electronic, magnetic and gyro compasses.Of course, in the modern world today, they have lost some of its relevance, as invented modern means of orientation not only on the ground but also in space.

Unfortunately, GPS-navigators help determine its own finding itself in a big metropolis, but in the forest, these devices are completely useless.Therefore, if you plan to walk in a small garden, then these means it is possible to use.

And if the campaign is scheduled for a few days in the thick impenetrable forest, you should still know how to use a compass.After all, unlike these modern scientific achievements it has millions of visitors compasses provided invaluable service.

on sale today found an abundance of different models of compasses.Mostly, they come to us from China, where craftsmen learned to make such devices, which combine high specifications with an attractive appearance.

But before you make the right choice, it is necessary to know not only how the compass, but also be able to establish the correctness of its operation.So, how it works is that permanent magnets compass interact with the horizontal line of the magnetic field of our planet.

freely rotatable about the axis of the magnetic needle by turning the set, and along the lines of the magnetic field.To check whether your compass, it must be positioned at a fixed horizontal flat surface.After stopping the arrows - to record the readings.

then requires arrow withdraw from the rest.It's enough to bring a compass for a few seconds magnet.After that, you should wait until the arrow again be at rest, and measured results, compare it with the previous one.

arrow at the serviceability of the device takes its original position.The same procedure is required to carry out 4-5 times.This magnet is necessary to bring a compass each time from different angles.

So the main thing - to understand how to use a compass directly on the ground, for example, in the woods.Initially, before entering the thicket, select the landmark, which subsequently have to get back.This facility should be required to "linear".

This means that the benchmark should have sufficient slowness.So, with this role perfectly handle road or river, power line or a clear firebreak, and a number of other similar objects.At either side of the guide must move at a right angle.

went forward a little in the right direction, you should turn to the landmark face so that approximately perpendicular to the path of return to the landmark.Turn the compass by holding it in front of you, you need to until the arrow is aligned precisely with the north-south line.

important to know how to use a compass, to testify it was as clear.To this end, it should be possible to keep the horizontal.Then the arrow will rotate freely, and thus will not touch the base of the unit or his glass.

through the center of the compass you need to draw an imaginary line in the direction of the path of return.Figures (degrees) at the edge of the flask, the zero-clockwise show the direction to the north.That figure, through which the imaginary line will reverse azimuth movement.The figure on the other side - direction in the depths of the forest.

But those who can not use ordinary compasses, today are increasingly interested in how to use compass 3D.It shows the location on the map through the Internet.It is quite functional device that requires minimal configuration, and does not give or get lost in a strange city or in the woods.
