The compass zeroing operation is a fairly important precursor to the use of the forest compass, and its steps are.

1. Place the compass horizontally. 2. Overlap the north zero scale outside the ring with the position of the hand indicating the north inside the ring, so that the completion step is to complete the north arrow to zero.

CompassIt can be divided into a lens compass, a case-type compass, and a transparent baseplate-type compass.

1. Basic compass. This beginner-friendly type has the basic features of a north quiver, and is inexpensive, but lacks some of the convenience and assistive devices such as adjustable declination lines and scopes.

2. Professional compass. If you are an outdoor activity player who already has the technology to use the compass, it is better to spend more money to buy this kind of compass with multiple assistive devices, which can make it more convenient for you to use the compass to determine the direction.

3. Decorate with a compass. These compass are often used as key rings or in conjunction with watches, and often do not have a baseplate to place on a map. Their function is to be able to quickly point out the general direction of the north, but not very precisely to point out the rest of the directions.

The compass is a tool used to indicate directions, and is widely used in various directions, such as navigation, field exploration, and urban roads.

Map reading and other fields. It is also an indispensable tool for mountaineering expeditions, and its basic function is to harness the Earth's magnetic field.

function, indicating the northern direction of the void, it must cooperate with the map to seek a relative position in order to know where it is. It is with a compass.

The north pole of the magnetic needle points to the north pole of the geography, and the direction of the indication can be discerned by using this performance. But in some parts of the world, the compass is also called the compass.

The compass is a tool used to indicate directions, and is widely used in various directions, such as navigation, field exploration, urban road map reading, and other fields. It is also an indispensable tool for mountaineering expeditions, its basic function is to use the earth's magnetic field to indicate the direction of the north, and it must cooperate with the map to find a relative position to know where it is. It acts the same as the compass, the north pole of the magnetic needle points to the north pole of geography, and the indicated direction can be discerned by using this performance.

But in some parts of the world, the compass is also called the compass.

The basic function of the compass is to use the earth's magnetic field to indicate the north direction, is a tool used to indicate the direction, the north arrow is also called the compass, widely used in various directions to identify and position, such as:

1. It is an indispensable tool for navigation, field exploration, and mountaineering exploration, and it cooperates with the map to seek relative positions in order to understand where you are.

2. The north pole of the magnetic needle points to the north pole of geography, and this performance is used to indicate the direction. It is used for the orientation positioning of urban roads, urban and rural buildings, and structures.

<> compass is divided into a lens compass, a case-type compass, and a transparent baseplate-type compass. The transparent base compass is widely used by outdoor activities, expeditions or explorers, and can also be used for mountaineering and river tracing activities. The compass is a tool used to indicate the direction and is widely used in various directions, such as sailing and staring at the sea, wild exploration, urban roads and other fields.
