[Specification] diameter 75mm, height 12mm

[Weight] about 82g

[Carries] hand-held

[Display] compass type

[Function] basic positioning

[Use]]

meaning of scale numbers on stainless steel compass:

south is 180

north is 0 (or 360)

east is 90

"West" is 270

the letters of the alphabet meaning:

east E

west W

south S

north N

NE northeast, SE southeast, SW southwest, NW Northwest

the red arrow points to the South
turn the compass, when the pointer is stable, the red end points North forever, and then gently turn the compass to make the letter "N" coincide with the Red Arrow (pointing to the same), then the direction corresponding to other letters on the compass is the actual orientation, so that you can distinguish between east, west, north and south, and then you can also determine the angle between any direction and the North or other directions, it can be read on the dial.

[Use]]

step 1: place the compass horizontally. After the compass is still, the red section pointing to the geographical direction is "south"

step 2: turn the compass slowly until the red end coincides with the "south" of the scale

step 3: The direction marked by the dial is the actual geographical direction.

Note: Magnet and iron objects will affect the accuracy of Compass. Please do not use the compass near magnet (such as Speaker) or iron (cutter, etc.).

[Maintenance and maintenance]]

1. Do not approach ferromagnetic objects, high-voltage wires, and electromagnetic devices when using and placing the north-pointing needle

parts, etc., in order to avoid errors and reduce the sensitivity of the compass.

2. When not in use, put it in a ventilated and dry place to avoid mildew.

3. When each surface is sticky, use white flannel to gently wipe the surface to keep the surface bright and clean.

[About Compass]]

compass is a simple instrument used to distinguish orientation. The predecessor of compass is Sinan, one of the the four ancient Chinese inventions. The main component is a magnetic needle which can rotate freely on the shaft. Under the action of geomagnetic field, the magnetic needle can keep on the tangent direction of magnetic meridian. The north pole of the magnetic needle points to the north pole of the geography, which can be used to identify the direction. It is often used in navigation, Geodetic Survey, travel, military and other aspects.

The Earth is a large magnet with south magnetic pole near the geographic North Pole and North Magnetic Pole near South geographical pole.
The compass is affected by the magnetic field force in the Earth's magnetic field, so it will guide one end and point to the north. Compass-people pay attention to the activities of the sun in history, which is called
the Northern Compass -- the northern hemisphere region is relatively close to the magnetic North Pole, and professional mapping needs to consider the declination (magnetic declination) between the geographic North Pole and the magnetic North Pole, so now most of them are called the Northern Compass. Both are one thing.

The compass must be held horizontally. In order to avoid magnetic needle disorder, it should keep a certain distance from barbed wire, high-voltage wire, cars and airplanes and objects containing magnetism.

[Compass knowledge extract]]

compass refers to South geographical pole, that is, North Magnetic Pole compass is a simple instrument used to distinguish orientation.

The predecessor of compass is Sinan, one of the the four ancient Chinese inventions.

The main component is a magnetic needle which can rotate freely on the shaft.

Under the action of geomagnetic field, the magnetic needle can keep on the tangent direction of magnetic meridian.

The north pole of the magnetic needle points to the south pole of geography, and the direction can be distinguished by using this property.

It is often used in navigation, Geodetic Survey, travel, military and other aspects.

The invention of Compass is the working people in our country. In the long-term practice, the magnetic property of objects understanding of the results. Because of the productive labor, people came into contact with the magnetic ore and began understanding of magnetic properties. People first discovered the nature of magnet-induced iron. Later, the directivity of magnet was found. After many experiments and researches,

finally invented a practical compass.

Principle of compass indicating direction

the Earth is a large magnet with south magnetic pole of it near the geographic North Pole, north magnetic pole is near South geographical pole. Compass is subject to magnetic field force in the Earth's magnetic field

therefore, one end of the guide points to the north.

[Operation]]

1. The measured azimuth

unfold the compass and rotate the azimuth frame to make the scale on the azimuth glass phase with the direction indicator. Right, put the flat sight mirror obliquely (45 degrees), single eye through the sight to the target, from flat the sight glass can see the azimuth division on the anti-Word Watch board against the North Pole of the magnetic needle, which can not only read the target, azimuth angle, and then turn the azimuth frame with the right hand to make the scale line and magnetism on the azimuth glass the needle is aligned with the North Pole, and the angle between the direction indicator and the azimuth glass scale line is the target direction angle (calculated clockwise).

Open the compass, mark the map (do not calibrate the map when ranging), and base on the map insert a needle at the spot, turn the north-pointing needle to make the measuring ruler edge cut to the target point, and then judge read the azimuth angle from the reference point to the target point.

2. The calibration map

unfold the compass and rotate the azimuth frame to make the scale line word and direction finger on the azimuth frame align (pay attention to the correction of magnetic declination), place the North pointer flat on the map one end of the star faces the north pole of the map, making the length of the coordinate ladder tangent to the magnetic meridian of the map, rotate the map to align the magnetic needle North Pole with the scale line on the azimuth glass. At this time, the map is calibrated.

[Compass introduction]]

compass is a senior professional compass for feng shui, and is a fan of feng shui of any school. First of all, the compass will show all the content needed by feng shui and make it exquisite, excellent material selection, a certain amount of weight, excellent hand feeling, is the heart of Feng Shui lovers A good tool for handling. It is easy to carry, elegant and stylish, and is a building, a test, etc. Essential tools for professionals.

"Compass", also known as "compass", is a master Feng Shui master of the Book of Changes in Chinese dynasties. An important tool for skyrocketing.
