What are the types of fishing life jackets?

1. Classified according to the occasion of use

It can be divided into two types of life jackets and Ship fishing.

2. Divide the buoyancy material

(1) Bloating material life jacket: It is mainly divided into two PAC buoyancy, which is softer to pinch.a little.

(2) Inflatable life jacket: The compressed carbon dioxide gas is breathable and inflatable to the inner biliary.It can also be divided into automatic inflatable life jackets and hand -puzzled life jackets.

(3) EVA foam life jacket: It uses the EVA foam material inside, which is compressed by 3D stereo molding, and its thickness is about 4 cm.

3. Classified by wearing

It can be divided into sea fishing neck -hung life jackets, sea fishing waist bag -type life jackets, and sea fishing waist Hanging life jackets.

What is the difference between fishing life jacket and ordinary life jacket

Sea fishing life jacket belongs to the category of life jackets, but also has its own unique product characteristics:

1. Easy to carry

Sea fishing climbing, climbing, navigation, swimming, etc. are common. The equipment weighs 50 or 60 pounds. Sea fishing users must climb away on the reefs and ask the sea fishing life jacket to be easy to carry!This is different from ordinary life jackets.

2. Small volume and convenient wear

It does not take up the place, it is easy to store, take it, it is convenient to wear, it does not take time, affecting fishing and fishing.

3. Not subject to action restrictions

It does not affect the play of fishing skills. After the fishing life jacket is worn, it does not affect the performance of people's movements, and let the fishing sprinkle freely, without a sense of restraint.

4. waterproof pocket

You can store it with waterproof pockets, and the sea fishing life jacket is equipped with waterproof pockets, which can be carried with bait, mobile phones, etc.

5. Following the buoyancy standard

Provide sufficient buoyancy. If you accidentally fall into the water, you can provide a sufficient buoyancy life jacket to make the human body float on the water without drowning.

6. Fortune to discover rescue

There are 3M anti -light films, for help whistle, etc. The fishing life jacket designed for the fisherman not only has the function of ordinary life jackets, but also has a pocket device of reflective and light -emitting warning bar and the same as fishing vest.Putting small fishing accessories for enough space and location can be described as two birds with one stone.

How to buy fishing life clothes

1. The surface of the life jacket is mostly water -resistant and breathable materials. In addition to paying attention to their buoyancy parameters, fishermen should also pay attention to whether there are damage to the junction interface and other places to prevent gravity without gravity.

2. Generally, a pair of oval glowing body on the chest or shoulders of life clothes is mainly used for maritime rescue to facilitate the discovery of the target. Therefore, you should pay attention to whether to open the sewing when choosing, and then consider the color blending fabric.

3. Regardless of whether you are fishing or fishing, sea fishing life jackets should try to choose more bright colors such as red, yellow, orange, etc., because once the fishermen are accidentally falling into the water, it can make the rescue easier to discover rescue in time.

4. When choosing a life jacket, you don't have to choose too advanced ones, but you must choose appropriately according to your weight.

The use and maintenance of fishing life jackets

1. From the beginning of leaving the land, we must wear a sea fishing life jacket to prevent falling into the sea.Most people are paralyzed, ignoring the important role of sea fishing life jackets, thinking that they have good water properties and do not need to wear sea fishing life jackets.In fact, after all, the sea is not land, waves, vortexes, reefs, bad weather in mutation, there may be danger at any time. Not only is the water properties good, you can have high pillows without worry.Needless to say.Therefore, when you are fishing in the sea, you must wear sea fishing life jackets at sea.

2. Do not perfunctory when wearing the life jacket. The two insurance bands at the back of the lower rear must pass through the legs.To prevent the life jacket from falling off from the head during water falling.Please be sure to tighten your thigh Belt, zipper or lifebone. When the equipment is incomplete, the life jacket will fall off or disrupt the body balance and cause danger.

3. There is also a life -saving whistle in Lidar, which is normally in the life jacket, which can make a whistle when the surrounding environment is bad and vision is not good.

4. In order to ensure its life span, you should use a brush to brush the inside and outside after each use, then rinse with water and dry it in the ventilation.When not in use, avoid direct sunlight and keep it in a good ventilation place. In addition, it will reduce its performance when it is wet by water or sweat.

5. As a cushion will reduce the buoyancy or cause deformation and deterioration, please absolutely avoid.Washing the paddy cotton will cause a decrease in buoyancy, please try to avoid it.

6. The recommended life is not more than two years.

Rainwear practical and fashionable

Whenever the storm, the rainproof effect of the umbrella can basically ignore it. At this time you need a raincoat.When we are rightraincoatWhen the impression was still on the "plastic cloth", the fashion guests had put on a practical and fashionable raincoat.

The bright raincoat itself can be worn as a fashionable single product, and it also has a rainproof function. The most important thing is that the bright colors can sweep the haze mood of rainy days.

The transparent raincoat can not only protect you from the wind and rain, but also will not cover the fashionable dress under the raincoat.When you get off the raincoat indoors, you are still a fashionable girl.

If you are too lazy to match and want to wear it eye -catching on rainy days, there are unique printed Raincoats to help you.

How can we use a plastic bag to rescue the field on rainy days?

It is not the same as the COOL KIDS with a general hoodie in a thin raincoat. He chose a printed T -shirt as an inner coat.

Astronomical Telescope purchase guide

Types of astronomical Telescope

The Telescope is usually focused by a telephoto mirror (main mirror) to focus the image of the celestial body, and then uses a (short focus) eyepiece to enlarge this image near the focus.Generally speaking, Telescope can be divided into three categories: refraction Telescope, reflecting Telescope and refractive Telescope.

Refractor

Generally, the objective mirror that reflects the Telescope is composed of two different discounted glass lenses to reduce the color difference and make the red and blue images gather on the same focus. This type of lens is called Achromatic lens.Strictly speaking, there is still a very lilac halo in the periphery of such lens images.

a. Blu -ray focus.

b. Huang Guang's focus.

c. Red light focus.

The color difference between the red, green and blue color of the Telescope.

In order to reduce the spherical difference of the lens, the comets and the AstigMatism can generally increase the focus ratio, so the caliber and focal length ratio (coke) of the longoscope generally reflect the at least from F10 toBetween F16.

The higher -level lens is composed of three different discounted glass lenses or made of lower -color (ED) or even fluorite crystals to eliminate the color difference between red, green and blue.These lenses are called apochromat.Their caliber and focal length can reach F5.The length of the Telescope is shortened and the weight is light, it is more convenient to use, but the price is very expensive.

Because the refraction of the Tube can be sealed, it is more convenient for maintenance, and it is more suitable for moving to the wild without being affected by the airflow of the lens barrel.

Because the lens is composed of at least two pieces of glass, the cost (four mirrors) is more expensive than the reflected Telescope with the same caliber.The small astronomical Telescope sold on the market is mostly refracted Telescope.

Reflector

The reflection Telescope is to focus on a concave glass plated (usually aluminum) plating (usually aluminum). Because the focus is in front of the mirror, it must be used to reflect the image outside the lens barrel with another mirror before the focus of the object mirror, and then use the eyepiece to put it large.

There is no color difference in the reflection Telescope (not scattered because it does not need to be through the glass), but there are other types of aberration.If the reflection concave surface is grinded into a parabolic, the spherical difference can be eliminated, but it is seriously affected by the comet shape, so the edge part is still loose.

At present, there are two types of small and medium -sized reflecting Telescopes:

Newtonian

A 45 -degree plane mirror (Flat or Diagonal) with a piece of light shaft is used as a secondary mirror to reflect the image to the front side of the lens barrel.This structure is the simplest, the image contrast is high, and the most people are selected. Usually Job is between F4 and F8.

Cassegrain (Cassegrain)

Use a Convex Hyperboloid as a secondary mirror. Before the focus of the main mirror, the light is gathered, and the main mirror is focused on the main mirror through the main mirror.Because after a reflection, the lens barrel can be shortened, but the field of view is narrow, like a lot of dispersion than Newton. At the same time, there are a little Curvature of Field.

Because the reflective Telescope only needs to grind a optical surface, in terms of the same caliber, the price is cheap than the refractive mirror.Ordinary astronomical enthusiasts have a lot of 150mm and 200mm caliber, and reflex Telescope can be worn at the same time.

Because the lens cylinder cannot be sealed, the main mirror is very easy to be affected by smoke and dust, so it is difficult to maintain. At the same time, it is greatly affected by the temperature and the airflow of the inside of the lens.The light shaft is also quite complicated, and it is not convenient to bring.In addition, the diffraction effect of the auxiliary mirror seat will make the star image of the light stars appear a cross or star -shaped diffraction pattern, and also reduces the image contrast.

CatAdioptric Telescope

This is a type of Telescope that uses the principles of refraction and reflection at the same time. It was used as astronomical photography by Schmidt in 1930.The main thing is to use a spherical concave mirror as the main mirror to eliminate the comet shape difference, and at the same time, a non -spherical lens (ASPHERIC INS) is appropriately placed in front of the main mirror as a correction mirror to correct the spherical difference between the main mirror.In this way, you can get a wide -torment (up to 40 to 50 degrees) fields without the common spherical difference between the spherical difference between the common reflex mirror. Only the mild color difference made of the correction mirror.The Schmidt Telescope for photography can be very small (usually from F1 to F3, minimum can reach 0.6), so it is very suitable for Hoshino and Nebula photography.However, the only disadvantage is that there is a certain venue, so the negative must also be changed to adapt (undertake with a special negative seat), and at the same time, the negative is placed in the long -distance lens barrel, so it can only be put in.

Generally, astronomical enthusiasts use Schmidt-Cassegrain (Schmidt-Cassegrain). It uses a convex mirror as a secondary mirror to gather the light before the main mirror focus.after.Because of a reflection, the lens barrel can be shortened, usually between F6.4 and F10.

In addition to the Schmidt-Cassegrain, there are also Maksutov designs.A round hole focuses on the main mirror.In recent years, the popular spinning Telescope such as "Celestron" and "Meade" are composed of Schmidt-Cassegrain principles, while "Questar", "Meade" ETX series and "Intes" use Mark Su.The principle of Toff.

The mirror body of the refractive Telescope is short, the focal length, and the focus is behind the main mirror, and the field of view is quite flat.In terms of contrast).

Hide fun

The blue sky, the white snow, when the sun is spreading, this is a gift from the world to us!Snowboard -an ordinary Tool, but the key to opening this gift, so that we can enjoy the fun of skiing! Make your body immersed in the tempting blue sky and white snow, galloping horizontally on the snow, and rushing along the snow channel, feeling the wind through the side, as if tore the air.Release ourselves as much as you can, feel the speed that the speed brings us, the passion is released from the heart to the body, and the energy bursts from the body to nature.Such temptation, even if a person who doesn't like to move no matter how quiet no reason does not like it.Speed and passion, this is the charm of skiing!

Best of skiing

1. Flexible body & strengthen balance ability

skiing is a systemic exercise that allows the nervous system to be fully exercised and improved.While bringing us speed enjoyment, we also have a good exercise ability, coordination ability and flexibility.The essence of skiing is to master the process of balance and find the balance point in the switching of the center of gravity, so as to make beautiful movements.This enhancement of this balance cannot be obtained from Running and playing.The closeness to the balance is coordination ability.Only by fully coordinating each part of the whole body can the best balance effect in the taxi.Ski is almost all the joints of the human body, neck, hand, wrist, elbow, arms, shoulders, waist, legs, knees, ankles, etc., which can play a better exercise role and activate a stiff body.Make the body's flexibility.

2. Burning fat

skiing, like Running and swimming, is also an aerobic exercise, which can enhance cardiopulmonary function.Ski requires strong lung capacity and good cardiovascular system support, especially in high -speed exercise, cardiopulmonary function will be better improved.At the same time, the cold air in the ski resort will test the body's oxygen transportation system, which exercises the ability of cardiovascular shrinkage in virtual.According to the test, a normal Ski person consumed 734 calories an hour, which is equivalent to Running 9.5 kilometers of exercise in 1 hour.Therefore, the effect of skiing on fat burning and consumption is quite significant.

3. Treatment of "winter fatigue chain reaction"

The temperature in winter is low, and there are fewer Outdoor (Weibo) campaign, which makes a considerable number of people choose to be indoors.There are fewer outdoor sports in winter. Lack of exercise causes people's physical constitution to reduce their physical constitution, which is easy to cause fatigue, which makes it easy for emotions to be low, concentrated, and low work and learning efficiency.These symptoms can be summarized as "winter fatigue chain reactions".The symptoms of the lack of training on weekdays are particularly prominent.We all know that exercise is the best way to change emotions, especially outdoor sports are particularly prominent in changing negative emotions and improving status effects.Therefore, skiing, as a unique outdoor sports in winter, can perfectly treat the "winter fatigue chain reaction", especially on the snow tract quickly and fast skins, the treatment effect is better!
