How about Da Yiwa fishing rod

Dayi Watt began in Japan in 1945. The well -known (famous) Fishing gear brand, Da Yifa's superb skills have always been known in the industry. It is the first brand in the world to add graphite to the fishing wheel. In 1965The aerospace technology engineering has joined the fishing Ship, and the waterproof and dustproof are first -class and excellent!

The Fishing gear produced by Dayiwa is regarded by the vast number of fishing enthusiasts around the world as the best of the dream. sales outlets and production plants are all over the world.Gentle and other.

How to choose a fishing rod

1. The carbon content of the fishing rod

How much talca rods are marked with T, 24T, 30T, or even 45T, etc. In short, it is carbon content. The higher the number, the higher the carbon content.EssenceThe higher the T value, the lighter and straight the fishing rod, but more brittle.Therefore, other materials need to be added during the production process of the fishing rod to enhance the elasticity and toughness of the fishing rod.Other materials are put in a lot, and the Fishing rods must be soft and heavy, so choosing a fishing rod is not suitable for high carbon seats.

2. The tone of the fishing rod

The tone of the fishing rod is whether the pole we usually say is soft or hard. In popular terms, it is where the fishing rod is bent. The closer the distance is, the harder it is.According to the description of the tonnage of the carbon cloth above, the harder the Fish rod should be, the greater.However, the choice of Fishing rods depends on the water environment and fishing species. Generally speaking, fishing fish and small fish are the best. The most classic is black pits. You must use a hard pole.

3. The feel of the fishing rod

Choosing a fishing rod is not as lighter and better, it feels light in your hand.The center of gravity is low.Therefore, in order to be strong, some Fishing rods will be made of solid. This kind of fishing rod fishing is still very suitable.

True and false disagreement method of Da Yiwa Fish rod

1. The gap between high imitation Fishing rods and genuine Fishing rods is very large. Generally, imitation goods appear on high -end products. High -end products are often made of high -tonnage carbon cloth.Secondly, the high -tonnage carbon cloth (Japan is limited to high -tonnage carbon cloth exports), so it is often used with low -tonnage carbon cloth charging, which causes the imitation goods to be poor, and also causes the imitation goods to lack the waist force during the fishing process.Although the brand factors also occupy a considerable part of the price of Fishing rods, the real fishermen, especially those who are engaged in competitive fishing, choose the fishing rod to choose from the actual performance of the fishing rod.

2. Pay attention to observe whether there are scratches on the body of the rod, and then touch it on the fishing rod with your hands to check whether there is a drum or concave place in the fishing rod.This inspection is the key to the quality of the fishing rod, must not be sloppy.If you find this kind of drums or recessed Fishing rods in a brand, it should be included in its own blacklist within a certain period of time, because it has a defect in craftsmanship and should be unqualified products.

3. Check the interface, extend each fishing rod, and then check the gap between each interface. The gap at the interface should be within 20 wires.Choose this kind of pole again.

4. Understand the back of the fishing rod and take out each fishing rod one by one. First, observe the two ends of each section to observe whether the wall thickness is uniform. If the thin thickness is uneven, then you must be sorry.Then check the inner wall of the fishing rod on the backlight. The inner wall must be glory. The interface of the rolling is not seen. If the interface or stubble occurs, you should immediately abandon these poles.

How to fish for high temperature days

one, fishing deep -water zone

Most fish are warmed animals, and they are warm and oxygen. They always like to stay in the most comfortable water body in water temperature.In high temperature in summer, the water temperature in the deep water areas is relatively low, and the fish groups generally hide in the deep water area to avoid summer heat.Therefore, in high temperature weather, you should try to catch the deep water area as much as possible.

two, Cowardly

There are large trees or bridges, such as large trees or bridges near the waters, and the water body covered by shade shade is relatively cool. fish group likes to gather in these locations. In the shade, it can often get better fishing effects.

three, fishing area

Many water inlets in the waters often form a deep pool due to the difference in water level. The water temperature here is relatively comfortable, the oxygen content in the water is sufficient, and there are more foods rushing upstream. It is a area with more fish.If you fish in such locations, it is likely to have a good harvest.

Four, bait flavor

In high temperature in summer, most freshwater fish like to eat slightly sour gravi or fruity foods. This is the food habit of fish in summer. The higher the temperature, the more you like to eat vegetarian food.Typical odors, while sour food helps digestion.The rich and fragrant fruit acid is a high -quality organic acid extracted from natural fruits. It is scientifically allocated into free acids through fish laboratory, which is the fruity acid that really has a effect on fishing.The food promotion effect in high temperature weather is significantly better than traditional fruit acid, and it also has a good fish -induced effect.

precautions for fishing in high temperature weather

1. fishing early fishing late, not fishing at noon

fishing in summer, paying attention to the morning or fishing. In the morning and evening of the day, the temperature is relatively low, and the fish is relatively easy to fish.But at noon, the scorching sun is empty, and the temperature and water temperature have reached the highest on the day. " summer fishing " It is also difficult to catch.At this time, it is not advisable to fish against the scorching sun. You should rest for a rest. 6 fishing after a minute.So if it is not rainy weather in summer, it is often morning. 11 You have to collect the pole before ordering, or afternoon 4 As well as 5 Click on the door to play wild fishing.

2. fishing in the wind and rain, not calm

fishing in summer, the wind is first.Insufficient oxygen in the weather without wind, the fish will float to the areas with more sufficient dissolved oxygen in the middle and upper layer, so it will be difficult to catch a lot, or even the mouth.If wind is windy, it will increase oxygen in the water and reduce water temperature, so it is best to catch wind, especially north wind, northeast wind, and northwest wind. Such wind direction is an excellent weather in summer fishing;The summer rainy days can still be caught throughout the day. Because of the weak light, sufficient dissolved oxygen in the water, the water temperature is cool, the activity of the fish is much higher than other weather, the eating time becomes longer, and dare to find food in shallow water.

But pay attention not to catch grass in summer in summer, because there is no grass when it rains " Lighter " The district, light and rainy, the water surface is cool, and the amount of soluble oxygen increases. At this time, the water live fish, and the fish is easy to bite.The dense grass gap is the opposite. Because the grass is covered with the water surface, the more the air -conditioning of the atmospheric circulation of the atmospheric circulation will be pressed, and the more the heat covered by the grass will be emitted, but it is covered by water plants.Slowly, the steam circulating hot water area was formed under the continuous water plants.In this way, the fish feels as suffocating and uncomfortable.

What is polarized Sunglasses

Polarizer can be divided into three types, namely straight polarizers, ellipse polarized and round polarizers.Generally, the so -called polarizer refers to the straight line polarization, also known as flat polarization.The vibration of this light wave is fixed in a specific direction. The transmission route in the space is a sine curve, and the projection on the plane of the vertical dissemination direction is the straight line.

The plane composed of a straight polarized vibration direction and the direction of propagation is called the vibration surface. It is vertically vertically from the vibration direction and the surface of the dissemination direction is called polarizing surface.Make nature light through polarizing mirrors, and can obtain straight -line polarizers, which are often used in crystal optical research.

The classification of polarizer

1. According to the material, it can be divided into: glass mirror of glass material, resin material polarized Sunglasses, and TAC lens material polarized Sunglasses.

2. It can be divided into: Ski mirror, fishing mirror, polarized driving mirror, outdoor sports mirror, golf glasses.

How to distinguish between Sunglasses and polarized Sunglasses

The first is the relationship between the two. The Sunglasses include polarizing mirrors, and polarizing mirrors are a kind of Sunglasses.It should be said that polarizing mirrors are a special Sunglasses designed with more and more requirements and designed.

Then let's talk about the difference. As long as we do not specifically pointed out, we generally have some Sunglasses that only have the two basic functions of obstructing strong light and worry about ultraviolet rays.Such Sunglasses are relatively single, the technical content is lower, and of course the cost is lower. Now many merchants sell ordinary Sunglasses as polarizing Sunglasses, which harms many consumers.

The biggest difference between polarized Sunglasses and ordinary Sunglasses is that this Sunglasses are treated with reflected light.In the environment of our lives, there are three kinds of light: direct light, reflection light, and shot light. Among them, we can not perceive the light shot light, but it is the most important light of our eyes that can see objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see objects.Direct light has a fixed light source (such as the sun), as long as it pays attention, it will not cause harm to our lives.

Only reflected light, because Smooth and flat planes can become reflexes. These common reflexes often reflect light suddenly, which will bring a lot of inconvenience to our lives.For example, driver drivers, the rearview mirror ahead is an uncertain reflective light source. The surface of the road on the road or the Smooth plane objects carried by passers -by can become a reflected light source. These reflex light may bring the driver of the driver.It is dangerous.

Polarized Sunglasses are the glare of reflected, filtering it, so that it can play a role in anti -dizziness, and traveling in summer will make the field of view more clear and reduce visual fatigue.Of course, such Sunglasses will also be much more expensive.

If you just go out, ordinary Sunglasses can fully meet your needs.But whether it is driving or outdoor activities such as mountain climbing and skiing, choosing a pair of polarized Sunglasses will make you easier and more comfortable.

When is it suitable for wearing polarizers

1. fishing

In summer, fishermen like to wear Polarized glasses.Why?The reason is very simple. Polarized Sunglasses have the effect of filter polarizing light. It is easier to wear fishing, and it is easier to watch.It feels more comfortable.

2. Driving

Polarized lenses are the most recognized lenses in the world.When the surface is reflected by the object, it is partially polarized and has a glare.The negative effect of glare -enhances brightness and weakens color saturation; the outline of the object is blurred, making glasses fatigue and discomfort.Polarized tablets make the polarization principle of light, which can effectively eliminate the special functions of glare, filter the messy light, improve the driver's vision and add fun to drive.

3. outdoor sports

Friends who love Outdoor leisure tourism are also exclusive to polarizing lenses. The polarizing mirror is composed of a balanced crystalline. This structure only allows the light waves to balance the crystal, and the light waves that shake to other angles are blocked.If the angle of the polarizer is adjusted, the shocking light reflected by the water surface, glass, flowers, water, water and other reflection can be blocked, and normal light can be partially passed, so as to enhance the contrast, reduce reflection, enhance the color of the scenery, reduce the atmosphere of the atmosphere,The role of fog phenomena makes you see the clearness of the world, and return you a colorful world, a blue sky, strong and beautiful nature.

The lens polarization angle and arc are specially designed and processed. The wearer will not have the feeling of distortion and dizziness of the scene. The resin polarizing lens has the advantages of lightness, difficulty in breaking, and easy to wear and comfortable.It is most suitable for fishing, driving, exercise, navigation, skiing, hunting, etc.

How to buy polarized Sunglasses

1. The first consideration is the quality of polarized Sunglasses

The primary function of polarizing Sunglasses is to prevent ultraviolet rays and filtrate polarized light. Good polarized Sunglasses lenses can block more than 90%of ultraviolet penetration. Please choose polarized Sunglasses with the best blocking of UV400 to the best obstruction of ultraviolet logo;The inferior polarization Sunglasses of the polarizing filtering function, such as dark Sunglasses, is darker with the light of the human eye and the pupils of human eyes will become larger, and the ultraviolet rays of the eyes will increase, increasing damage to human eyes.

2. Will there be discomfort for a long time?

Genuine polarized Sunglasses must be comfortable to wear. If you feel uncomfortable, dizzy, headache, dry eyes, tingling, etc., please take it down quickly;

Meicoscopy belongs to inferior or imitation generally causes dizziness and headaches. Generally, inferior lenses are not technical and functional when manufacturing.The damage can be described as a loss.

3. Focus on the protection function of the frame

The protection function of polarizing Sunglasses Apart from the basic functions such as anti -ultraviolet rays, avoiding strong light dazzling, and filtering glare, most polarizing Sunglasses frames are designed with surface arcs. In outdoor sports, it can effectively prevent wind and foreign body stimulation. In additionThe hardness of the lens and the flexibility of the frame of the frame must be considered whether it will hurt the human body.

4. Polarized Sunglasses should be true and natural

The color selection of polarized Sunglasses should be based on the color of the surrounding environment, the edges of the object are clear, and the principle of effectively identifying different color signal Lights.Especially when driving Sunglasses, it is guaranteed to drive safety.The color of the lens is better in gray, tea, and green, because these colors of lenses are better absorbed by infrared and ultraviolet rays, which can improve visual contrast and clarity. Wearing effects in severe air pollution or fog.

How to identify the quality of polarized Sunglasses

1. Generally, there will be instruments that detect Sunglasses to resist ultraviolet capacity. You can know if the glasses in your hands meet the standard through instrument detection.

2. The simple way to test the quality of the Sunglasses is: you can use the ultraviolet light issued by a banknote pen or a banknote check machine to observe the UV logo pattern on the RMB through Sunglasses. If the quality of the Sunglasses is poor and there is no blocking of ultraviolet rays, it can still be clearly clear.When you see the UV logo pattern on the RMB, on the contrary, if the quality is excellent, you can't see it.

Why war warm up before exercise

Heating before exercise can increase the activity of the joints, improve the core temperature of the body, awaken muscles, and make the muscle contraction and relaxation more efficient.In addition, warm -up will effectively reduce the phenomenon of joints, muscle sprains, and strain during exercise.Here are some warm -up movements. Before exercise, remember to do a few groups:

10 major actions of sports warm -up

Neck rotation

Mobilize the head back and forth to pull the neck muscles.A total of 3 groups need to be performed in a total of 10 times, and each group is allowed to have a rest time of 5 to 10 seconds.

C -shaped

Stand upright, stretch your arms, and draw a movement of a C from high to low.A total of 3 groups need to be performed in a total of 10 times, and each group is allowed to have a break of 10 to 30 seconds.

Side arm movement

Holding a light dumbbell with a light weight or not taking it, slowly swinging his arms with an angle.A total of 3 groups need to be performed in a total of 10 times, and each group is allowed to have a break of 10 to 30 seconds.

Hip joint rotation

The upper part of the body is leaning forward, the waist is bent down 90 degrees, the body is up, bending to the left to right, and stretching.A total of 3 groups need to be performed in a total of 10 times, and each group is allowed to have a break of 10 to 30 seconds.

Squat

The main activity of this action is the knee joint. When doing this action, pay attention to the body not to tilt forward, while the squatting action is mainly slow.A total of 3 groups need to be performed in a total of 10 times, and each group is allowed to have a break of 10 to 30 seconds.

Arrow squatting

When squatting in arrows, we must let our hips and legs work, feel the tension of the hip and leg muscles, and keep the back straight and the abdomen tightening.Don't let our knees exceed our toes, and try to keep our legs bending 90 degrees.

Hip Running

Picking the hip Running can fully stretch the thigh muscles, and help the second half of the Running posture in the Running gesture.You can do one -foot exercise in place first, use the muscles on the back of the thigh to lift the heel backwards, touch it with your hips, and then try to take turns or move forward easily.

Lift your legs after alternating prone

Lift your legs after leaning can help us activate the muscles of the hips and legs, and can also help us activate the abdomen muscles.First lying down on the mat, or keep the tablet support, and then lift our legs back alternately.

Open -closing jump

Open -closing jump can help our body quickly heating up in a short period of time, allowing us to be in a high degree of excitement, and at the same time, it will also allow our cells to be moved in the whole body. This is very good for our next training. At the same timeIt will also reduce the chance of injury when we do some high -intensity movements.The opening and closing jump must control the speed, do everything you can, keep the movement speed, and keep your arms and legs straight, and make our movements as much as possible.

High -lifting

The last action is to recommend a faster training movement to everyone, that is, raising legs.Raise your legs with both feet.Try to raise your own limit.A total of 3 groups need to be performed in a total of 10 times, and each group is allowed to have a break of 10 to 30 seconds.

Warm -up precautions

Water supplement

Pay attention to the water before warm -up, especially under hot and humid weather, and can also prevent cramps and heat stroke.

Warm -up

When warm -up, pay attention to gradual progress. The best exercise amount starts from small, gradually increases to achieve the effect of sweating.Don't be too severe to avoid fatigue.

Warm -up time

The time of warm-up exercise is 10-14 minutes. Depending on age, personal constitutional differences, seasons and temperatures, the time required for warm-up exercises will be different.When the weather is cold, the warm -up time should be extended to 20 minutes.It should not be rushed to take off the sports jacket and trousers before you sweat, which will hinder the effect of warm -up.

In fact, every movement of warm -up is very knowledgeable, and it is by no means just stretching at will, and the wrong movement will even cause muscle breaks or joint damage. It is better not to do it.The real warm -up is to keep the muscles soft, and then increase the range of the joints, so that we can make more correct Running or movement postures.Want to become flexible, strengthen the sense of balance, and no longer fall easily. Don't forget to warm up before exercise!
