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.

1. What is the material of the Outdoor celestial scorpion?

Outdoor sky -to -scalpel is a good partner at the time of Camping. Compared with tents, its tall sky can create a sense of open space. Therefore, it is often used with the camps.After the rope is stretched, you can build a variety of Outdoor sky curtains. Friends who like outdoor activities must have a top. So what kind of material is the general Outdoor celestial scope?

The main fabrics of the sky curtain are Oxford cloth and pure cotton. Oxford cloth also has nylon and polyester. You can choose polyester Oxford cloth. It is strong and light -resistant and light.Suitable for hot weather, silicon coating is more suitable for the rainy season. The common waterproof index is generally between PU1000-3000. We can choose PU1500. Remember to see the sunscreen index and waterproof index when buying.

2. What color does the Outdoor Sky -to -tear Tent is well -inspired?

I have learned about what materials are better in the cannish shade, so in terms of color, what color is good for insulation?

The darker the color, the hotter, we can choose the light color such as white white in spring and autumn, and we can choose dark brown and other dark colors in winter.Based on the bright and dark color of the sunshade fabric, it is slightly different in reflective radiation, radiation transmission, absorbing radiation absorption light, and ultraviolet transmission.

The above is the introduction of the material of the Outdoor sky -to -teanter and the content of the color heat insulation of the Outdoor sky -to -sunbud. I hope to help you. There are many content introduction of the sky -to -teana on the homepage. Welcome to view it!

Can you dive if you can't swim?

Can't swim to dive.Diving is the kind of travel diving with oxygen cylinders. It is possible to go to the sea as long as it is simple training. The premise is that there are no restricted diseases, such as hypertension of heart disease.Before diving, there will be a coach to teach you, and the process is very simple. You only need to master a few basic actions and gestures.

Types of diving

The submersible is divided into: hard diving, soft diving, semi -closed lock circuit air supply type, should be delivered, and self -sufficient air.

Divided by diving: non -saturated diving, saturated diving; types of breathing gases: air diving, nitrogen, hybrid gases (artificial air diving), mixture, oxygen mixed gas (artificial air diving), hydrogen, oxygen mixed gas (hydrogen, oxygen, mixed gas (Artificial air diving), other hybrid gases.

What are the Diving equipment

1. Facial mirror

The diving mirrors on the market now are mainly divided into three types: silicone, rubber, and PVC; rubber and PVC materials generally have some odors. The rubber material has rarely appeared in the leisure market. Generally, a few diving mirrors are made of silicone materialsIt is non -toxic and tasteless. The price is slightly more expensive than PVC, but it is softer, more durable, and more comfortable to wear.

The appearance is mainly divided into dual lenses and single lenses. There are no differences in these two uses, and the field of vision is similar. The advantage of dual lenses can be equipped with close -up lenses; the selection is mainly based on whether it meets its face shape and personal preferences; there is another kind of one; there is also one is that there is one.Fullface mask; Full mask, the design of this type of mask makes the divers not have to include the respirator in the mouth and combine the communication interface, mainly to enable the diver to achieve underwater calls; mostly for engineering diving.

2. Breathing Tube

The material of the respiratory Tube is also mainly divided into silicone, PVC, which is better for silicone tubes; structures are divided into all-dry and non-dry type;It is welcomed by junior players to prevent water from entering; but from a practical perspective, it is still a traditional non -dry respiratory Tube with simple structure and smoother breathing.

Buying note: The choice of respiratory Tube must meet the principles of ergonomics and mechanical design. The diameter size and length must be appropriate to facilitate drainage, and the design of the water stop valve must be available to prevent seawater from pouring in.The part of the bite should be the best choice for bite comfort.

3. Cold -proof clothing

Cold -proof clothing, also known as diving suit.It is mainly divided into wet, semi -dry, all -dry, wet type divided into 3 mm, 5 mm, 7 mm and other thickness.Wearing semi -dry and full -drying potentials, you can keep your body not wet, and you can also wear warm clothes in the interior. The insulation effect is the best.The choice of diving coats is mainly determined according to the water temperature of the diving environment; tropical or temperate waters, 3 mm thick wetwear are the most commonly used; the lower the water temperature, the thicker the need to choose a divingSemi -dry or full -drying; all dry clothes can even achieve under ice diving.

Buying note: In order to achieve the effect of preventing the cold, the cold -proof clothing must be fitted, soft, easy to unload, and not easy to deform, and does not affect the ability of divers to move.Secondly, choose the tricks you like.detailed

How to achieve ear pressure balance when diving

1. Pin the nose and breath.Ear pressure balance refers to the same techniques that make the pressure in the ear the same as the surrounding environmental pressure.Generally, the more commonly used way is to pinch the nose and drum, pinch the nose, block the nostrils, and gently breathe with the nose. At this time, you will feel that the eardrums are swollen and giggled.

2. In addition to the method of pinching the nose, you can also reach the ear pressure balance by swallowing the mouth, yawning or swinging the mandibular mandibular.

Essential emergency safety knowledge for diving

1. Cache

If psychological tension, too cold water, or staying in the water for too long, cramps may be cramps.The preparation activities before the water should be sufficient, don't take too long in the water.Once cramps occur, don't panic.For example, the toe cramping, then immediately flex the legs, pull the toes open and straighten the toes; the calf cramp, take a breath first, lie on the water on the water, stop the toes with the hand plate, and stretch the calf forward.Stretch and relax the contracted muscles; when the fingers are cramp, hold it with a fist, and then open it hard to liberate it so repeatedly.

2. Dizziness

The main reason is that the diving time is too long, the blood is gathered in the lower limbs, the cerebral ischemia, and the body's energy consumes greater the body's excessive fatigue.Immediately go ashore to rest, keep your body insulation, and drink some light sugar salt water appropriately.

3. Nausea, vomiting

The nose will be dirty water.Hurry up ashore and then press Zhongli and Neiguan with your fingers.To prevent enteritis, you can also eat a few petals.

4. Itchy eyes

It may be caused by poor water.After ashore, you should rinse your eyes immediately with clean saline, and then use chloramphenicol or erythromycin eye drops. It is best to make hot compresses before going to bed.

5. Headache

The reason may be inadequate blood supply to chronic rhinitis, water or body cold, temporary cerebrovascular spasm.At this time, you should go ashore quickly. Use your thumb to press the top of the head, the sun and the lack of acupoints, and then apply it with a hot towel, and drink a cup of hot boiling water to improve.

6. Abdominal pain blocked

Just after eating or diving on an empty stomach can cause abdominal bloating.At this time, you should go ashore to lie on your back, press the tip of the toe to the middle courtyard, go to the courtyard or Zusanli, and take 3 to 5 ml of water at the same time at the same time, and apply the abdomen with a hot hand towel.

7, ear pain, tinnitus

It may be that the ears are irrigated or the nose is watering, and the head can be tilted to the side of the ears. Pull the earlobe vigorously and use the same side leg to make a single foot jump.Or the palms of the palms of the ear canal, block the ears tightly with your hands, tilted your head in the left ear to the left, and then quickly pull the hand, and the water will be sucked out.

8. Itchy Skin and rash

Main Skin allergies.Immediately ashore.If you take a piece of Stimi or Poemin, it will soon improve.

What do you need to pay attention to in diving exercise

1. First of all, for beginners, diving is still difficult, because diving is a systematic engineering. If you want to make high -level diving, you should learn slowly. As a beginner, you should accept high -level diving. It is best to accept it.Related training.

2. Follow the principle of the two of them, that is, two people need to stay together from entering the water to the shore. They must keep together. When diving, keep up with the coach and always connect with the coach's gestures, so that it is safer.

3. When choosing diving, we must choose a regular and safe diving area. Do not choose cheaper areas because of expensive prices, may be cheap areas, no safety guarantee, and belonging to informal diving enterprises.

4. You should wear equipment before diving. This is necessary. Check whether the equipment is fit and the function is normal. Learn the use of respiratory Tube and regulator, surface rest method, emergency treatment, etc.Of course, two people can help each other to check the equipment.

What are the benefits of diving

1. Performance

The leisure diving that people yearn for is in a state of weightlessness. Entering a completely different space, let people completely relax the body and mind, let everything casually and natural, watching a variety of colorful on the bottom of the quiet sea.Strange corals and fish.Communicate with your companions with gestures and eyes.This feeling cannot be obtained on land, and people who have not really sneaked into the sea cannot be obtained.

2. The exercise of the body

Diving exercises can increase lung activity, enhance the strength of the main muscle groups, improve swimming skills, exercise physical fitness, and even lose weight.

3. Getting knowledge

In addition to being able to master many physiological, physiological and medical knowledge and marine biological knowledge about diving, you can also learn first aid, drowning rescue and other knowledge.

4. fitness, beauty

Because diving breathing is a compressed air, oxygen molecules can better penetrate into the Skin through the flow of blood and speed up the Skin's metabolism, thereby achieving the effect of beauty and Skin.Because the heat energy consumed in the water is larger than on the land, diving exercises have also become a good way to lose weight and fitness.

5. Temk of will

Diving can also hone their will and cultivate the spirit of the team.Diving can exercise the psychological quality of people, let people learn how to face strange environments, and enhance the ability to deal with crisis and emergencies.No matter how high the divers and diving coaches are, they must strictly abide by the submarine companion system. They must not dive alone. The partners must take care and help with each other.

Do you bring a rope when you go out and Outdoor?If you do nt carry it, it is recommended that you put a few special ropes of different diameters and different lengths in your bag when you finish the loading. The rope weight is light and easy to carry.1000 grams, the weight of the ten -meter 5mm static rope is about 200 grams. Bringing the rope will bring great convenience to your outdoor activities, and it will also bring a certain security guarantee to your outdoor activities.Don't simply think that carrying ropes is just a matter of leader, and the Outdoor environment is different. I hope that everyone will constantly explore more ropes in outdoor activities and play more functions of ropes.It is good to use the rope to expand some self -rescue.What needs to be reminded is that everyone should choose to buy a special rope (UIAA-Gundenglian Certification Product). Usually, you should often check the integrity (wear) status of the rope.And the practical method of knot ropes and ropes.Let's talk about some of your previous wild experiences about the various uses of ropes (non -mountaineering, Rock climbing version) when surviving Outdoor survival.

1. Dangerous road sections can be trapped and the auxiliary personnel can be passed by ropes. When multiple people pass at the same time, do not fix the rope on the body and Backpack.Way).

2. You can be used as a cold (sun) rope when you are resting. You can also tie up the canopy with the environmental needs, hand warfare and other things.

3. It can be used to make a simple stretcher for bundling, and can also support the use of aluminum alloy bars, tree sticks and other parts with the need to use aluminum alloy bars, tree sticks, etc. (using shoelaces to be bundled with the use of aluminum alloy bars, tree sticks, etc.The next policy).

4. Detecting the depth and rough width of the ditch, the depth and general width of the ditch (adopt a binding stone to the opposite side, judge the width according to the water falling point of the stone), and can use the rope to transport the personnel and equipment such asUnder the security and stable front question, rope can also be adopted with high and low -fixed slip methods).

5. lighting and anti -animal torch handles, under special circumstances, close the ropes on one end of the dry branches, and then pour the carried fuel oil or consumption oil to ignite. This method is characterized by the burning time and more durable.

6. It can be used as a night camp alarm and pull rope. After Hiking and Camping, due to the deep degree of sleep and sleep, you can tie the two ends of the rope to the GG and MM tents. Once an accident occurs, you can pull each other to wake up. You can also follow the camp according to the camp.The environment pulls the rope as a warning rope in the camp (the rope can be tied to the items that can make a crispy sound that can make a crispy sound).

7. In the narrow and slippery and steep slopes where the Backpack is not convenient to carry the Backpack at the same time, the rope can be used to use the method of separating people and Bags to pass.

8. After the personnel slip (fall), you can use the rope to implement rescue (according to the actual situation, you can use multiple ropes in parallel or series) to climb the better helping personnel.The length is generally controlled within the length of the human body. If the rescuer is a woman, the rope can be appropriately shortened. If necessary, you can also use multiple ropes to edit the soft ladder.

9. In the dangerous location (such as steep slopes, cliffs, etc.), the road personnel are used for safety protection on the line staff.

10. In the high temperature season to prevent food deterioration, the food can be closed (sink) into the water body and tied them on the food Bags and shore trees or other objects to prevent the water from being flushed away.

11. Used to strengthen the Tent under special weather conditions, it can enhance the wind resistance and snow resistance of the Tent.

The correct way to wear the bloated life jacket

1. Put your head into the life jacket.

2. Tie the straps on the left and right sides.

3. Pull the tension on the left and right sides, the inflatable valve is opened, and the life jacket is inflated within a few seconds.

The inflation function of the qi -blee -type life jacket

1. Manual inflatable: Pull the pull rope on the inflatable device before or after falling or after falling or after falling or after the water, so that the tie rod is not less than 90 degrees, the thorns are pierced to pierce the gas cylinder film, the high -pressure CO2 gas is poured into the airbag, and the buoyant is generated after the gas swells.

2. Automatic inflation: After the water is dropped into the water, the life jacket is immersed in the water to soften the water sensitive element in the automatic device, loses blocking the needle, and the spring stretch pushes the piercing needle to pierce the gas cylinder sealing film CO2 gas to fill the airbag and generate buoyancy.

3. Blowing the mouth is a one -way valve type, and the one -way valve is automatically closed after blowing.

What are the types of qi -style life jackets?

Blay -type life jackets are divided into three types according to the appearance style:

1. Vest -style qi qi and life jackets are commonly known as horses -type qi qi life jackets.

2. scarf -style qi and life jackets are tied to the neck like a scarf.

3. Belt Bloating life jacket, also known as qi -type Belt life ring, water seat Belt.

There are two specifications of all styles of qi and life jackets, one manual type and one automatic type.Suitable for fire, maritime police, water police, armed police, border defense, maritime affairs, fishery administration and other units to engage in water rescue activities.

The performance indicators of qi -blee -type life jackets

1. Automatically inflatable within 5 seconds of water, generate more than 15 kg of buoyancy.The 24 -hour buoyancy loss is less than 5%, and the performance of the main accessories and materials meets national standards.

2. The airbags are made of imported polyether TPU materials, which have excellent aging resistance and hydrolysis characteristics.

3. The dry side of the water is greater than 120mm, and the backward angle is 20-50 degrees.

4. The product is standard for search whistle and reflective stickers.

What are the fabrics of qi -qi -type life -saving clothing

Bid-type life jackets use TPU fabrics, TPUs (Thermoplastic Polyurethanes), and thermal plastic polymethlate, which is a linear embedded cluster composed of low polymer polymirol soft segments and diisocyanate-expansion hard segments.The TPU can be made of saliva, film blowing, pressure delay, or coating, which has the excellent characteristics of good elasticity, strong toughness, abrasion resistance, good cold resistance, and environmental protection and non -toxic.TPU fabric has the following characteristics:

1. Hardness planning wide

After changing the ratio of the components of the TPU composite fabric, the Tent cloth can get products of different hardness, and follow the hardness of the hardness. Its product still adheres to excellent elasticity and abrasion resistance.

2. High mechanical strength

The carrying capacity, impact resistance and shock absorption function of TPU composite fabric products are excellent.

3. Extremely cold -resistant

The glass state changing temperature of the TPU composite fabric is relatively low, and the canvas factory still adheres to excellent elasticity, softness and other physical functions at minus 35 degrees.

4. Good processing function

TPU composite fabrics can be processed with common thermoplastic materials, such as injection molding, extrusion, pressure extension, and so on.At the same time, the TPU composite fabric/cloth processing with certain polymer materials can obtain a polymer alloy with complementary functions.

5, oil resistance, water resistance, mold resistance.

6. Good recycled utilization.

There are two methods of TPU composite fabric. One is called and then sticked: first make it into a TPU film, then fit the glue with the fabric, and the other is called online composite: apply the glue on the fabric may not be glued.The fabric is made into a TPU composite fabric or clipped mesh.
