How to use a sight to aim

1. Visual differences return to zero

Newly bought new sights need to complete an important task before use: to zero the vision of the scope to reduce the shooting error and improve the accuracy.

2. school sight

Select the target target 10 meters away, aim at the target heart, take 5 rounds as a set of shooting, and adjust the knob according to the position of the bounce.For example: the bouncing point is distributed at the bottom right of the target heart, adjustable air biased knitting knobs, rotating the knob along the direction of L, so that the bounce point moves to the left in the horizontal direction, until the bounce point is basically directly below the target heart;Rotate the knob along the U direction, so that the bounce point moves slowly upward in the vertical direction until it basically coincides with the target heart.

The method of debugging of the scope

1. Set a white paper target, order a black spot at the target heart, hit the centers centered on the black spots, and then retreat to one hundred meters to set up a gun to fix the table, install the sight on the gun.

2. Remove the bolt, aim at the black spot on the white paper target from the barrel through the refractive mirror, and then hold the gun body, then press the cross from the sight of the sight to the black spots on the white paper target. Tighten it tightened.Aiming at the mirror adjustment knob.

3. The guns do not move in a fixed state, install a bullet with a bullet, and start!

4. Check the bomb point. If you are too upper, you can fine -tune the sight of the sight. If you are partial, fine -tuning, and the left to the left, and the right is fine -tuned to the right.

5. Take another shot and look at it again. Repeat this method until the bounce point is hitting the black spots on the cross on the white paper target, and the sight will be adjusted.

The debugging skills of the scope

1. When aiming, pay attention to the distance of the pupil, that is, the distance between the eyes and the sight, and the pupil distance has two effects. One is to avoid damage caused by the rear power to the human eye when shooting.The person's eyes can get the largest imaging area at the distance of the pupil.

2. When aiming, the human eyeball must be the same as the axis of light aiming, otherwise there will be vision.Aiming errors.On time, the surrounding shadow areas are uniform ring -shaped. The performance of the vision is that the shadow areas around the imaging area are uneven. Once the crescent area appears, the projectile will be biased towards the larger part of the crescent area.

3. There are two buttons in the middle of the sight. There are protective caps on these two buttons. After you spin the lid separately, you can see these two buttons.The button in the middle is increased.For example: there is a UP, one is down, and the direction of the UP will be automatically corrected upward.If you turn in the direction of down, the original bounce point will be automatically corrected downward.UP means upward in English, down means downward.The bounce point is biased down, and the direction of the UP indicator is turned. If the hit is high, follow the direction of writing down.In the knob on the side, the above is written by L, and one is written by R. If you turn along the direction of L, move the point to the left. If you turn in the direction of R, the bounce point will move to the right.L and R are capital of the first letters in English left and right, respectively.

4. Aiming a look at 1/4 inches at the British 100 yards (equivalent to 91 meters).The discounted public system is 6.35 mm.If there are about 30 mm (3 cm) in the horizontal direction of the bounce point and the target heart. If a grid at 91 meters is 6.35 mm.Then the actual movement volume of a grid at 10 meters, a look at the grid, is equivalent to 1/4 inches at the British -made 100 yards (equivalent to 91 meters).The discounted public system is 6.35 mm.There are about 30 mm in the horizontal bomb and target heart. If a grid at 91 meters is 6.35 mm.Then the actual amount of movement at 10 meters is to remove 9.35 with 9.35.Finally, about 0.7 mm.The adjustment amount is 30 mm.With 30 divisions of 0.7, it has to be screwed about 43 blocks.If it is a 30 -meter adjustment of one grid, it is 2.16 mm. If 30 meters 30 mm, it is 13.8 that is to twle out 14 grids.

Is the quality of the Dayi Watshu Line good?

1. The PE line of dense and weaving

Each raw wire is thicker and rounder than the previous silk, which has achieved strong improvement, abrasion resistance, improvement, and durability.

2. Rich model lineup

62 models (8 edits)/37 models (4) can be used in various fishing methods.You can choose more suitable fish wires according to target fish, fishing spots, and preferences.

X8 Total: 62 models (color: 43 models; Lym green: 19 models)

X4 Total: 37 models (color: 18 models; coral red: 19 models)

How to choose Da Yiwa fish line

1. The tensile strength of the line

The question that fishermen often care about is whether this fish can be pulled up?Will the fishing line be broken?This is the problem of the tensile strength of the line, that is, how much "fishing power" is.We are usually distinguished by the number of "number", and labels will be indicated on each line shaft you buy.

In the same wire diameter, the stronger the tension, the better, it is not easy to disconnect the fish Running fish.In addition, the tensile strength of the fish line at the knot will be reduced, and the quality of good quality will be much smaller.The strength of the fish line is affected by the external environment.As the purchase time becomes longer, the light or oxidation will cause the line to aging and the intensity will be reduced.

2. wear resistance

During the fishing process, the lines and underwater rocks, weeds, and other objects will be worn after contact. If the quality of the fish wire is not good, it will soon start with hair or split, which will affect the original tension of the fish wire.In order to enhance wear resistance, manufacturers have specially developed some abrasion -resistant components.Of course, this characteristic must be measured in order to compare.

3. The elongation of the fishing line (exhibitors)

The elongation is divided into two types: recoverable elastic extension and deformation, and non -recovered plastic extension and deformation.At any time, the detective does not recommend using a fish line that is easy to extend and deform.The elastic extension is good for slipping fish.In addition, the low -extension fish wire tie is stronger, and the feedback of fish bite hooks is more sensitive, which can be used as a sub -line.

4. Softness

When choosing the fish wire, pay attention to the softness of the fish wire. In the same case of the fish wire diameter, the softer the wire is, the better.A good fish line should be very soft, especially the soft line as a sub -line, which has many benefits.Because the tough line is easy to curl the curls in the water, the fish is difficult to hook.Due to the curved line, the information of the fish bite is slow, and it is not accurate.

5. The proportion of the line

That is, the density of the line, the density of the line is greater than the water, which means that the water of the line is good (cutting water). After the fish wire enters the water, it is quickly sinking into the water, suitable for child lines.The density of the line is less than water, and the lines easily float up, which is very useful for water meter fishing.Generally, nylon wires have larger buoyancy than other types.

In addition, some inferior fish lines are rough in workmanship, the density density of the wires is insufficient, and the waterproof protection layer is not effective. After soaking the water, water absorption will occur.A good fish line should not be absorbed.

Does black sunscreen suck heat?

Black sunscreens suck heat when wearing.Scientific experiments have proved that the deeper the color of the clothes, the more the heat is absorbed, because its reflective performance is not as good as white, bright yellow, etc., which will cause less light to be reflected and more heat absorbed, so in the summer, in the summerWhen wearing dark clothes, it is often slightly hotter than white clothes.However, the black sunscreen has its advantage, that is, it is more sunscreen than other colors of clothes, and its radiation resistance to ultraviolet rays in all colors of sunscreen is the strongest.

What color is the best color of sunscreen

Black sunscreen jacket is hot but cool than other colors, white clothes cool, but not as good as black and blue, but both performance, so each color sunscreen jacket actually has their own characteristics.Choose dark colors, if you want to be cooler, choose light -colored, there is no best color.

How to choose sunscreen

1. Look at the line

When choosing a sunscreen, the thinner the texture of the sunscreen cloth, the more compact the sun jacket is, the less transmitting the light transmission, and the effect of such sunscreen and sunscreen will be better.It shows that the Sun protection effect of the sun jacket may not even have no sunscreen effect.

2. Look at the material

There are about four materials on the market on the market, namely polyester fiber fabrics, silk fabrics, cotton fabrics and nylon fabrics.Among them, the Sun protection sunscreen effect of polyester fiber fabrics is the best. Therefore, when choosing, you should try to choose polyester fiber sunscreen.

3. Look at the color

The color of dark sunscreens reflects ultraviolet rays better than light -colored sunscreen clothes, so when choosing sunscreen, you should choose dark sunscreens instead of light -colored sunscreen.

4. Touch the feel

The impermeable sunscreen jacket will generally feel very loud, so you can rub the sunscreen clothes when buying. If the sound is loud, try not to buy it.You should try to buy a comfortable, no loud sunscreen jacket, so the sunscreen clothes are breathable, and it is comfortable to wear.

5. Look at the label

The sunscreen jacket with good sunscreen effect will be identified on the label that the sunscreen index of ultraviolet rays, that is, the UPF index is higher than 40, the transmission rate of the sunscreen clothing is that the UVA index is less than 5%, and the sunscreen index with poor sunscreen effect will not reach thisStandards may not even have this logo.

What is a sight

The origin or optical aiming device is difficult to verify.It is said that at least in the 16th century Europe, some people have tried to fix the glasses lens on the butt.There are text records that before the 19th century, the firearm had a long -mirror -type aiming device, which could be used for aiming under low light conditions.The scope can be divided into holographic scope, internal red and green scope, and laser sight.

Blame classification

The scope is mainly divided into the following three categories: the long -term scope, the precipitation scope, and the reflective sight.Among them, the Wangyuan sight and reflective sight are the most popular.The above two types of sights are mainly used during the day, so they are collectively referred to as the white light scope. In addition, there are night vision sights for night aiming (adding night vision devices to the above two types of sights, and night vision device according to night vision deviceThe types of types can be divided into micr -light sights, infrared sights (can also be subdivided into two types: active infrared and thermal imaging).

What is the principle of the scope

The scope has both enlarged function and the function of fast aiming.Natural light is absorbed from a optical fiber -made lighting system at the top of the aiming mirror, and a targeting mark is formed by a split plate and then reflected into the eyes of the shooter.

Both the bullets and the sight can be seen as a ray approximately. Two rays located in the same plane and in one direction are either parallel or intersection. In fact, the point in the scope is exactly the ray of the scope and the ray of the bullet.The intersection, the parabolic line of the bullet and the sight line have two focus, as well as the target sight.

The intersection of the scope of the scope and the ray of the bullet may not necessarily fall on the target. This requires adjusting the distance between the scope of the scope and the intersection of the ray of the bullet.In order to adjust, the viewing angle of the sight installation is needed according to the target distance.If you want to make precise shooting, you need to consider the impact of the wind direction, which is the so -called repair.

Is the scope a prohibited product?

At present, it is not included in the category of prohibited products. The sight can be regarded as a collection of things, such as the sights replaced by the collection equipment, which is normal.

The scope generally does not belong to a prohibited item. The criterion for measuring the non -committing is whether there is any harm to others and whether it harms others and national interests.The scope is not a military weapon, not to mention that ordinary sights are only attributed to toys (unable to compare with military regulations).

There is also the purpose of this sight. If it is used to sin or harm the interests of others, of course, if not, it is just a normal Tool.

99%of people will be wrong, scientific first aid to break rumors

Nosebleed: Be bowed, don't look up at your head

In order to stop the nosebleeds, some people may choose to look up at the sky, but in fact, doing so can not promote hemostasis, and they may pinch the blood into the trachea.The scientific approach should be to lean your head slightly and pinch your nose to compress the hemostasis. If you have the conditions, you can also help it.Cotton or toilet paper in the nasal cavity may interfere with the local coagulation process, so it is not recommended.If the bleeding is still non -stop after ten or twenty minutes, please ask the doctor for help.

Scald: To cool down, do not oil, salt, vinegar Flour toothpaste

From applying toothpaste and applying Flour to wiping large sauce, folk recipes for treating burns can be described as a variety of.However, these things are not helpful for treatment of burns, and they may cause wound stimulation or even infection.When scalding, what should be done is to reduce the local temperature with cold water as soon as possible. Do not apply toothpaste or oil and salt sauce vinegar, and seek medical treatment in a timely manner.

Dripping eye drops: To drip the conjunctiva, do not dripping eyeballs

Eye drops can't always drop?It may be that your eye drops are wrong.It is a better way to drop the eye drops into the center of the eyeball and drip the eye drop into the conjunctiva (where the lower eyelids and the eyeballs).In addition, the capacity of the conjunctival sac is very small. Each drop of potion is enough to fill it up, and it will be wasted if you get too much.

Take medicine: the pills raised their heads, the capsule bowed her head

In order to go smoothly, people generally "raise their necks", which is useful, but it is not suitable for capsules.In the capsule, the filling of the drug is relatively loose, so the density of the capsule is relatively low. It is easy to float up and stick up and down when it looks up.Therefore, when eating capsules, bowing your head will be smoother.Don't look at this trick very simple, it has research support to improve drug swallowing.
