How does a spirit level level water?

Establish an instrument for measuring the height difference between two points on the ground with horizontal sighting. The main components are the telescope, tube level (or compensator), vertical axis, base and foot screws. According to the structure, it is divided into micro-tilting level, automatic leveling level, laser level and digital level (also called electronic level). According to the accuracy, it is divided into precision level and ordinary level. ①Tilt the level slightly. Obtain level sightlines using a slightly angled spiral. Its tube level has small division value and high sensitivity. The telescope and tube level are integrated into one. The tube level is slightly tilted in the vertical plane thanks to the slightly inclined spiral, so that the level is centered and the line of sight is level. ②Auto leveling instrument. Get Level Sightlinesthanks to the automatic leveling compensator. When the line of sight of the telescope is slightly tilted, the compensator moves the telescope relative to it under the action of gravity, thus quickly obtaining the ruler reading at the line of sight. This instrument is more efficient and more precise than the slightly inclined level. ③Laser Level. Uses laser beams instead of manual readings. The laser beam emitted by the laser is fed into the telescope tube to emit a horizontal laser beam along the collimation axis. Leveling can be carried out by equipping the leveling rod with a photoelectric receiving target which can automatically track; ④The digital level, which is a newly developed level in the 1990s, integrates advanced technologies such as optomechanics, computer and image processing, and is a modern The result of the latest technological developments. The levelWater appeared after the invention of the telescope and the level in the 17th and 18th centuries. At the beginning of the 20th century, the slightly inclined level was made on the basis of an internally focusing telescope and a leveling instrument. Anping automatic level appeared in the early 1950s, and laser level was developed in the 1960s. In the 1990s, digital levels developed. Slightly inclined level A commonly used level that uses a slightly inclined spiral to achieve a horizontal line of sight. During operation, first use a circular level to roughly level the instrument. Before each reading, use a slightly inclined spiral to tilt the level in the vertical plane until the level bubble is precisely centered and the line of sight is level. Compared to ordinary levels, slightly tilted precision levels have higher reticle valuessmaller and higher sensitivity, while the telescope has higher magnification and brightness. The structure of the instrument is solid, especially the connection between the telescope and the tube level. optical micrometer and equipped with precision level scale to improve reading accuracy. The slightly inclined precision level produced in China has a telescope magnification of 40 times, a tube level with a division value of 10″/2 mm and an optical micrometer with a minimum reading of 0.05 mm. The aiming part of the telescope, the tube level and. Optical Micrometers are all installed together in the heat shield.

Please adopt the correct drift adjustment method for wild fishing

You can completely pull the float into the. water by pulling on the float seat, then allow the float to reveal 1-2 stitches. This also completes the search for the approximate bottom, then twill bring the float down to exceed the length of the sub-line, cut the lead skin and let the float escape. the float reveals the red color of the tail. Click, this completes the water leveling. In fact, the water may not be leveled in actual operation, you can also expose 1 mesh

In this way, the water leveling is completed, then the double hooks are baited, move up the float, then.Expose 1-2 mesh to the float, so that both baits are at the bottom, whether you are using baits by pulling, rubbing baits, regardless of the specific gravity of the bait, or using insect bait, even if you hook just one red. worm, the bait will be at the bottom at this time.

Due to the differences in fishing positions and fish conditions, when fishing, choosing a suitable fishing method does not is not just about worryinguse only one method. When fishing, you should use it flexibly. There are no rules to catching fish.
