Tips for using geological hanging plates

The poster is talking about the geological compass or the 65-type compass.

The key advantages of this small instrument are compact structure, small size, light weight, easy to carry, simple operation, reliable accuracy and stable performance. There are many types, but the structure is basically the same. It consists of a magnetic needle, a dial, an inclinometer, an aiming plate, a level, etc.

Now I will introduce in detail the role of the geological compass in Feng Shui practice. The usage of The angle from the meridian to the survey line clockwise). Therefore, the fixed position is also called the intersection fixed point, which is the direction and position of the target.

Use the geological compass to open the compass. Release the magnetic needle and align the azimuth indicator "△" with "〇"; turn the compass. After the north end of the magnetic needle is aligned with "0", the direction pointed at this time is north, and the current east, south, west and north directions can be directly read on the azimuth glass. Hold the instrument with your right hand, with the reflector facing away from the observer's arm (when the target is below the line of sight, the reflector faces the arm) and close to the body to reduce shaking, then use your left hand to adjust the reflector and rotate the body so that the target is reflected in the reflector and Bisected by the mirror line, make the aiming tip coincide with the mirror line, and keep the round bubble in the center. At this time, the degree indicated by the north pole of the magnetic needle is the direction of the target.

2. Determination of building direction

Building direction is the direction of the intersection between the building and the horizontal plane, which is the extension direction of the horizontal line at any height. Our Feng Shui is called sitting direction. In the past, when using a compass, you had to extend the guyed wall and then measure the extension cord. The ones currently on the market are generally square discs, with the inner disc rotating and the direction determined by the red cross lines. When in use, close one side of the square disk to the wall, rotate the disk to make the Tianchi meridian coincide with the pointer, and the direction of the mountain pressed by the red line is the measured line position. The geological compass is used in the same way. When measuring, place the long side of the compass close to the wall of a certain direction of the building, then rotate the compass so that the bubble of the chassis level is centered. Read the scale pointed by the pointer as the direction of the building.
