1. How to use the dual -Tube Telescope

Step 1: Rotten or folded eye mask

Rotten eye mask: Friends who do not wear glasses to observe the eye masks, and friends wearing glasses observe the eye masks.

folding eye masks: Friends who do not wear glasses do not need to turn over. Friends who wear glasses turn the eye masks when observing.

This is to keep the eyes and eyepiece of the pupils properly. If you stick it too close or too far, you will feel that there is a dark shadow in the vision and cannot get a complete vision circle.

In addition, if a friend who does not wear glasses is observed, the eye mask is not spinning, and the eyelashes can easily be scraped into the eyepiece lens to contain oil, which affects the imaging clarity. The observation will be blurred.

Step 2: Adjust the pupil distance

Many friends say that the Telescope always sees two rounds, and there are black shadows in the middle that cannot be re -coexized, because the pupil distance is not adjusted.Operation method: Well the distance between the two lens cylinders and adjust it to the same distance from your eyes, so that the image can be overlapped.

People of different ages are different. For example, children's pupils are relatively small, and the distance between adults is relatively large.The distance between the two sides of the lens barrel is adjusted to the same distance as the pupil distance, so that the image can be re -observed and there is no dark shadow.

Step 3: Cocume

Slowly rotate the focus wheel focusing and adjust the definition!

Add the visual dialogue:

Some people have different eyes, such as 100 degrees left eye and 300 degrees right eye.After taking off the glasses, you will find that your eyes cannot be clear at the same time, because the eyes have vision.At this time, you can first turn the middle focus wheel to make the left eye clear, and then slowly rotate the right mirror or mirror to compensate for fine -tuning, and the eyes can be observed at the same time.

Generally, most Paul Telescope is to rotate the right -eyed mirror micro -adjustment compensation vision:

Some friends received the Telescope because they were unfamiliar, and when they saw the right mirror or dialogue, they could turn it directly to the end.However, if the eyesight is normal, the difference is turned to the end, so no matter how you rotate the focus wheel focusing, there will always be blurry, and you cannot get a clear imaging at the same time.Therefore, everyone should also pay attention to this. Generally, if you can see the differential ring at the same time, don't move to the end.

Tips:The binoculars on the market are generally divided into roof spine structure and Paul structure. In fact, the operation method is roughly the same. There may be a slight gap between the Telescope of different brands.TelescopeThe manual prevails.

2. precautions for the use of dual -Tube Telescope

1. Do not observe the sun directly with a Telescope, which will cause serious damage or even blindness to the eyes.

2. Do not fall to the Telescope, avoid shocks, so as not to observe the light shaft to be dizzy and bloating.

3. Do not touch the lenses in your hands to avoid affecting imaging definition on the lens.

4. Don't watch the Telescope while walking to avoid accidentally stepped on dangerous objects and cause personal injury.

5. Don't put the Telescope in the car or sunlight under the scorching sun for a long time to avoid the aging of accelerating the rubber at high temperature.

6, waterproof Telescope does not need to keep dry for a long time, which can prevent the lens from growing mold in a sealing bag with desiccant.

7. Do not put the desiccant in the Telescope at the place where the child can get to avoid the child from swallowing the desiccant to cause damage.

8. After using the Telescope mirror, cover the lens cover and eyepiece cover to avoid dust falling on the lens.

Third, double Tube Telescope maintenance contraindications

Although there are a lot of waterproof Telescope on the market, there will be no problem with even if it falls into the water.But in terms of maintenance Telescopes, preservation Telescope in a dry environment is harmless to the baby's coating and Telescope.Waterproofing and nitrogen -filled functions are only in case of water falling and moisture, and they are not afraid of being subject to moisture.RememberDo not use it in rain and snow in non -waterproof Telescope.

Do not try to clear the interior of the Telescope or disassemble the Telescope. The Telescope is actually very complicated. If the light shaft is broken, it must be debugged on the dedicated to debug the light shaft of the Telescope.As soon as the Telescope is disassembled, the light shaft will change, so that the imaging of the left and right Tube will not be overlapped, making your glasses uncomfortable, and in severe cases, you cannot use it at all.Do not fall, pressure or do other violent actions for the Telescope, mainly because of the light shaft of the Telescope, and it is easy to destroy the optical axis of the Telescope.Double -Tube mirrors are the most available impact, especially cheap models.

1. How to choose Camping lights

Outdoor Camping is a more popular way of vacation. Many friends will also be Camping overnight. If it is Camping overnight, Camping lights are essential. There are many Camping lights on the market. Choose carefully when choosing.When choosing Camping lights, the following points are mainly considered:

1. lighting time

It is an important criterion for choosing Camping lights for long -term stable and continuous and continuous stability. When buying, you can check whether the Camping light has a built -in charging system, whether there is a charging cable, etc. to determine its lighting duration.

2. lighting

The output of light is measured by lingering. The higher the flow, the brighter the light. The brightness of the general Camping light is between 100-240 lumens.In the outer camp, the Camping light with a large brightness is required. When buying, you can test the brightness of the Camping light.

3. Portableness

When performing Outdoor Camping, people hope that they can be lighter while meeting the needs, otherwise it will be very troublesome. When buying Camping lights, it is recommended to buy the Camping light that can be suspended at will and the light size is lighter.Facing complex Camping conditions, it can play its role.

4. waterproof

Out of Camping, it will inevitably encounter a humid environment, and even hitting rainy weather. The waterproof performance of the open camp Lights is particularly important, and the waterproofness of the dew was tested.

5. Functional

In addition to the lighting, there are some Camping lights that can achieve multi -functional requirements, such as acting as mobile power, fan, etc. Multi -function Camping lights are not only better, but also can make camping equipment lighter.

2. What are the standards for choosing wild Camping lights

There are many types and products of Camping lights. When choosing, pay attention to selecting a good Camping light. Generally, good Camping lights need to meet these standard requirements:

1. The brightness is appropriate

Professional Outdoor Camping lights will have the brightness value of the output, but it should be noted that the lingering is not the only determined factor in brightness. The selection of Outdoor open camp Lights should be processed from actual use needs, rather than simply request the brighter and more demanding.Good: 2 ~ 3 people will light up in a Tent at a lumen of 100 lumens; when Camping and cooking or group Camping, multiple Tent lighting should be more than 200 or more.

2. Strong durability

The durability of Camping lights mainly depends on the shell and waterproof ability. Usually high -quality plastic materials can well meet the requirements of toughness and falling resistance. Try to choose some round and flat styles when buying.It is necessary to have some waterproof ability to deal with humidity and foggy weather.

3. Light and easy to use

A good Outdoor Camping light is not only lightweight when carrying, but also convenient when used; the placement form of open camp Lights on the market is mostly: suspension, magnetic suction, flat release, clarify your main use scenarios to buyJust accept it.

What is the speed reduction?

The average downhill speed of the skiers varies from model. The skiing speed of professional athletes can reach more than 150 miles per hour, but the speed of most casual Ski people is between 10 and 20 miles per hour.

The speed of the downhill car is 40-60 miles per hour, while the Olympic athletes tend to Ski at a speed of 75-95 miles per hour, depending on the conditions, equipment and body composition;Go downhill at a speed of 156.2 miles per hour.

Speed and off -road skiers downhill speed

According to the current world record holder Simone Origone's 156.2 miles/h, the speed skiers wear aerodynamic clothing and slide down the mountain directly without turning, and can drive 156 miles per hour.One of the world's fastest women's speed skirs is Sanna Tidstrand, Swedish skiers, reaching 150.6 miles per hour.

As for off-road Ski people, professional racing drivers have an average of 15 miles per hour and a continuous distance of 35 miles. Most of the top Ski racing drivers are driving at a speed of 20-25 miles per hour.The speed of miles is driving, while the casual off-road skiers fly at a speed of 7-10 miles per hour.

How to increase the speed of lowering skiing

Generally speaking, the skiing board is more straight, the tighter skiing, and the faster the skiers go downhill, but often avoiding obstacles such as trees or skipping the slope will significantly slow down the athlete's movement.The important part of remembrance when trying to improve the speed of the speed is to first develop sufficient core forces to control the skiing plate at high speed.

Try to faster skirs should always wear suitable safety equipment, because speeding up speed will lead to the possibility of severe injuries. Although the idea of accelerating the hillside seems to be attractive to amateur skiers, they should first develop appropriate skiing techniquesTo avoid impact and injury.

How to control the direction of skiing too fast

1. Specification:As the name implies, a one -time reduction speed is mainly to brake.The horizontal board of the single board is rubbing the snow, the double -board -plow brakes and the side brakes and some alternative brakes, such as the hip brake head brake face.Another deceleration plan is to slide on the mountain and turn kinetic energy into potential energy.

2. Uniform speed:Control speed in a relatively uniform range.For almost all methods of taxi, you can control the speed by selecting the path (control bending). For example, each curve slipped more to the mountain, or when the curve is changedStrong, you can flatter the curved shape, such as strong pressing (Cabbin) or strong twisting (snow) at the top of the arc, and control the acceleration process by reducing the time to point the snowboard to the rolling line.When the terrain limit cannot be adopted, you can adjust the technical movement. For example, rubbing a little more at the end of each curve can also play a role in controlling the speed.

Is the Camping cushion a moisture -proof pad?

Camping cushions are also a kind of moisture -proof pad. Camping cushions are also known as grass floor mats, Outdoor field pads, beach pads, Tent bottom pads, etc., which are mainly used in the suburbs, garden grasslands.The Camping pads are soft and easy to carry, which can be destroyed by the grass, providing a good rest environment for the Camping.

The functional characteristics of Camping cushions

1. There are various grass scraps on the Outdoor grassland. Sitting directly on it, these grass scraps will be stained with the whole body. Put the items carried by you directly on the grass, which is easy to stain and affect the mood.These.

2. The network structure of the Camping cushion makes it have excellent breathability. On a few Square meters of wide grassland, the scope of human activity is relatively small.One layer of protection.

3. Camp pads are easy to carry and organize.Lay various foods on the wild camp pads. After the Camping is finished, it is simple and convenient to clean up these "endgames". It is not necessary to find the vegetation or the natural environment on the grass.

4. Camping cushions are made of high -grade fabrics or non -toxic PVC materials. It has high rebounds, moisture -proof, cooling, insulation, comfortable and beautiful.When the photographer is shot or the family is on the green, rest on the lawn or beach to rest and eat for meals.

What kind of material is good for Outdoor Picnic cushions?

1. Oxford cloth

Oxford cloth is used as a Picnic pad to be wear -resistant, washed, and has a moisture -proof effect, and Oxford cloth is also a kind of environmentally friendly material.

2. PVC material

PVC's Picnic cushion is also a category that everyone sees more. This material is also environmentally friendly material.Compared with Oxford, it may not be so convenient when carrying, but it has a good moisture -proof performance. Therefore, it is also a type of products that people choose more.

Introduction to waterproof fabric

waterproof fabric is a new type of textile fabric, which is made of polymer waterproof and breathable material (PTFE film) plus fabrics with fabrics.The main functions of waterproof and breathable fabrics are: waterproof, humidity, breathable, insulation, windproof, warmth.

In terms of production technology, the technical requirements of waterproof and breathable fabrics are much higher than ordinary waterproof fabrics.At the same time, the quality of the waterproof and breathable fabric also has the functional characteristics that other waterproof fabrics do not have.While strengthening the dense and water density of waterproof and breathable fabrics, its unique breathability can quickly discharge water vapor inside the structure, avoid the structure of the structure, and keep the human body always dry.The problems are a new type of fabric of healthy and environmentally friendly.

Real waterproof fabrics can also be able to withstand water seepage pressure in a humid climate and environment for a long time, and do not seep water.For example, walking outdoors for a long time, Kneeling or sitting on a humid ground, will not seep water.

How to wash waterproof clothes

All E-PTFE film clothing can be washed.There is no permanent waterproof performance loss after washing. The surface DWR dialing function is lost and it can be simply repaired.

1. The waterproof fabric is more resistant to dirt. Add some detergent in the water. After soaking for 10 minutes, use your hand for a few minutes.Just dry it.

2. The blue cloth stained with vulcanized fuel, the adhesion of the general color is relatively strong, but the abrasion resistance is poor.Therefore, it is best to soak in the detergent for 15 minutes, rub it gently with your hands, and then rinse with water.Don't rub it with a rubbing plate, so as not to be white.

3. The green cloth made of oxidized fuel is generally strong and shiny, but it is easy to green when it encounters gas such as gas.Therefore, don't put the washed green cloth clothes on the stove.

4. If waterproof jackets are waterproof fabrics with coatings, they generally do not need to be washed frequently. When it is not too dirty, scrubbing with a humid and humid towel.Wipe it a few times and twist the towel again, and then scrub it repeatedly.If the inside is also dirty, you can use hand -washing method to put it in the bathtub, more warm water, detergent or meals, and grab a lot of washing.Then completely overwhelm the foam water, and finally put it in the washing machine to dehydrate.

precautions for waterproof clothes washing

1. You need to pull your waterproof jackets, buckle buckles, stick magic stickers, and restore the wind rope on the stretching hat -otherwise it will cause the fabric to distort.

2. Do not add a softener -the soft agent may cause the gel barrier, the fit film, and the lining to get rid of it, and the clothes are scrapped. Even if it is not so serious, the production of bubbles is inevitable.

3. Do not use hot water and warm water -waterproof clothing is afraid of high temperature.

4. Usually the drum is better than the wave wheel, and the wear and tangling of clothing are less, but it is not necessary.

5. Do not dry it. The waterproof fabric lining has a quick drying nature, and it does not absorb a lot. It does not take any effort if it is Hanging to dry. Do nt harm it with strong centrifugal force.

6. If you cannot determine whether the washing fluid used contains a soft agent (mostly), use the material such as washing powder and washing agent to wash.
