What's the difference between diving and snorkeling? With the coming of summer, many people like to go swimming, because swimming can make them cool in hot summer. People who like snorkeling must pay attention to safety. Actually, diving is divided into diving and snorkeling. What's the difference between diving and snorkeling? Come and have a look with me.

What's the difference between deep diving and snorkeling? 1 What's the difference between deep diving and snorkeling?

1, which means snorkeling

Snorkeling, according to the water surface, refers to floating and diving on the water surface. In fact, it's more than that. Snorkeling also includes a series of skills such as diving, exhaling, ascending and draining. You can snorkel through diving goggles, breathing tubes and flippers. Floating on the sea, you can watch the underwater scenery through the mirror, and then breathe through the breathing tube. You can simply dive without more equipment.

2. Deep-sea diving and snorkeling

Deep diving is more complicated than snorkeling. You need to wear diving equipment and know some diving skills. You can do underwater activities accompanied by a coach. Deep diving mainly refers to scuba diving, breathing underwater with compressed air bottles. Snorkeling can only see some fish and corals in shallow water, while deep diving is to enter the deeper underwater world and see more wonderful underwater animals.

3. Preventive measures

Snorkeling is not difficult, but you should also pay attention to safety. When diving, use a breathing tube to control breathing. Don't get too excited and nervous. Be fully prepared before going into the water. If you feel uncomfortable in the water, you should go ashore in time. Don't go deeper alone to avoid danger.

What should I pay attention to when diving?

1, two people must stay together (in and out) from entering the water to landing.

A skilled person (coach) should not let his companions go ashore alone.

3. People who swim in front (skilled people) should always look back at their peers and slow down with their physical skills.

4. People who swim in the back (beginners) should stay behind their peers.

Disposal when you are alone:

1, stay calm.

2, float a few meters, broaden your horizons (looking for companions).

3. If nothing is found, float to the surface and pay attention to the bubbles on the surface.

4. If nothing is found after more than 10 minutes, you must go back to the original water entry point (shore) to find it.

Several important gestures:

The meaning of gestures may vary from person to person (from place to place) a little, so be sure to communicate well before you start.

1, ok

2, pay attention to (object) direction

Step 3 dive

Step 4 raise

5. The air will disappear.

6. Give me air

7. The out-of-breath gesture is the gesture that should be made when the remaining pressure gauge is 30kg/cm square.

Question 6: Can myopia dive? Can I wear contact lenses when diving?

Myopia can be diving, diving can wear contact lenses. People who are nearsighted can also buy glasses with degrees if they don't wear contact lenses.

Question 7: Can women enter the water during their physiological period?

The answer is yes. You can use tampons. Just out of the water, keep warm and don't catch a cold.

Question 8: I have experienced diving in Sanya, but my ears hurt. I wonder if I'm not suitable for diving?

This is a frequently heard problem, which mainly occurs in Sanya. I don't know how many people with diving enthusiasm in Sanya have been hurt by diving instructors before.

Water pressure will be generated under the water surface, and 10m will increase one atmospheric pressure. Even in the swimming pool more than one meter deep, sensitive people will feel the change of eardrum when diving. This is a normal phenomenon. Diving ear pain is due to the pressure of water pressing the eardrum, which is associated with the pain of pulling the surrounding muscles. You only need to do a simple ear pressure balancing action, and you won't feel pain. This action, according to the truth, should be taught by the coach whether it is diving class or experience diving.

Question 9: What is free diving?

Free diving refers to the diving activity of taking a single breath and holding one's breath without carrying underwater gas supply equipment. Free diving includes free diving activities such as entertainment, experience, photography and hunting, as well as extreme breath-holding deep diving of competitive nature. Simply put, diving with one breath without a gas cylinder is free diving. Similarly, our average person's free diving only refers to leisure free diving, not competition.

Free diving is also divided into different levels of courses, different levels and different depths of practice. The higher the level, the greater the depth and the higher the technical requirements. At present, there are associations that do well in free diving, such as SSI and AIDA, and SSI has developed Chinese free diving textbooks. The study of free diving needs to find a professional free diving instructor.

Question 10: How was the underwater photo taken?

There are two main types of cameras that want to take underwater photos:

1, the camera itself is directly waterproof.

2. Ordinary cameras are equipped with special waterproof housings for cameras.

Direct waterproof camera has the advantages of:

Small size, light weight, easy to carry, do not worry about the waterproof shell in case of water leakage to damage the camera. Simple and convenient operation.

Disadvantages are:

Limited waterproof depth and limited imaging quality. It is inconvenient to install external equipment.

Therefore, the direct waterproof camera is more suitable for snorkeling players and beginners.

If you want to get better imaging effect, you still need a better camera and waterproof shell. Now, whether it is a card machine, a micro camera or a professional SLR camera, there are professional waterproof shell manufacturers to produce matching waterproof shells. The price of a good waterproof case even exceeds the camera itself.

Question 1 1: Where can I learn to dive?

Two suggestions for learning to dive:

1, you must study in the open water, that is, the ocean.

2. Consider going to Kenting, Taiwan Province to learn diving.

Basically, diving shops near Shanghai will offer diving courses, which means everyone can learn to dive. China's big cities now have inland diving shops.

What's the difference between deep diving and snorkeling? 1. What does snorkeling mean?

On the surface, snorkeling is diving on the water, but in fact, snorkeling is not just browsing on the water, but also the cultivation of many skills and knowledge.

Snorkeling also includes skills such as floating, diving, ascending, drainage, ventilation, breathing, self-help and equipment selection and use. In addition to the coordination of individual motor nerves, coaches and a series of courses are needed for education and practice, and the practice of many skills should first consider dangerous situations.

Second, the characteristics of snorkeling

1. Breathe the air through the breathing tube, so you don't need to keep looking up for air to save a lot of physical strength, and you can also watch the underwater scenery conveniently and clearly;

2. Drain water through fins with drainage area more than 5 times that of Bigfoot surface, thus generating the driving force for swimming on the water surface;

Snorkeling can only be seen in shallow water, and some fish and corals can also be seen.

Three, the main equipment of snorkeling diving goggles

Diving goggles can make people see the animals and plants at the bottom of the water conveniently, and leave a cavity in front to make people see clearly. Moreover, in order to prevent squeezing when snorkeling, it is necessary to balance the pressure in the nasal cavity. Diving goggles are generally covered with noses.

The general diving goggles are composed of reinforced safety glass lenses, rubber or silica gel edges that fit the face and adjustable headband that can be fixed. breathing tube

When snorkeling, breathing tube is a necessary equipment. When your face is looking down in the water or looking for something, you can breathe through the breathing tube, or when there are waves on the water surface, you can also use the height of the mouth of the breathing tube to prevent water from pouring into your mouth.

The general design of breathing tube is an elbow with one end open and the other end biting. The upper part (tube) of the breathing tube is usually a semi-rigid plastic tube, and the interface tube in the lower part is mostly silica gel. fin

Flippers, commonly known as frog shoes, can provide you with powerful motivation, so that you can do other things without paddling. Fins are mainly divided into two types: heel-less and sleeved, and fins with sleeves are generally selected for snorkeling. gloves

Because hands often come into contact with rocks or creatures, wearing gloves can provide adequate protection. diving suit

Wearing a diving suit when snorkeling can completely protect the body covered by clothes from sunburn, keep the body temperature when the water temperature becomes cold when diving for more than 3 meters, and also avoid scratching the body when being pushed by the current to rub against rocks or other things.

Fourth, the practice skills of snorkeling

Before snorkeling, you need to practice some corresponding skills to minimize the accident rate in sports. Mirror drainage

The mirror may get water when snorkeling. If the water can't be discharged or keeps flowing, you need to check whether there are the following problems:

1. Whether the mirror is worn correctly.

2. Is there any hair or foreign matter between the mirror and the face?

3. Whether exhaling through the nose is gentle and lasting. Respiratory tube drainage

The probability of water entering the breathing tube is very high, so you need to master some skills of emptying the breathing tube when snorkeling:

1, jet is to exhale the air in the lungs from the mouth. Because most of the current breathing tubes are designed with drain valves, there is no need to exert too much force on the strength of exhalation.

2. Gas expansion type This drainage method is designed for the breathing tube without drainage valve to rise after diving. In the process of floating at the bottom of the water, spit out some air in the pipe first and look up at the water surface. When it reaches the water surface, the water in the breathing tube will naturally be squeezed out of the tube by the expanding air. Breathing control skills

Snorkeling is also very important for respiratory control, which can reduce the production and accumulation of carbon dioxide.

1. Diaphragm breathing means that every inhalation on the water surface is deeper than usual. Because of deep inhalation, of course, the speed of snorkeling will slow down because of the breathing speed, but it can increase the exchange capacity of gas and relatively reduce the proportion of residual gas.

2, rapid breathing This breathing method is used when swimming fast on the surface of the water. This kind of breathing can be adjusted according to the kicking speed of frog shoes and can be decided by yourself, but rapid exercise and breathing can't last long, and long-distance or long-term use may lead to hypoxia.

Snorkeling can be said to be a popular sport now, which belongs to diving, but some people may not know much about snorkeling. Let me introduce some snorkeling to you.

Five, the steps of snorkeling

first step

Equipped with comfortable snorkel and mask. Try it on and adjust the elastic band. If you can, try to get water in the water.

Second step

Wear a mask and an elastic band to cover your eyes and nose comfortably. Make sure the diving tube is close to your mouth. Don't put it on yet. Put on your flippers.

Third step

Lie flat on the water in a prone position. The head is about 45 degrees above the water.

Fourth step

Gently bite the joint of the snorkel, wrap it with your lips and adjust the direction of the snorkel.

Step five

Breathe slowly and smoothly through the tube. Take a deep breath slowly and carefully. Don't be afraid of water, you can always raise your head and breathe on the water. Relax and control your breathing. When you can clearly hear your steady and rhythmic breathing, you can relax and enjoy the beautiful scenery on the bottom of the sea.

Six, the benefits of snorkeling

1, snorkeling can feel the magical world in water and master some skills of underwater survival.

2. Regular snorkeling exercises can develop muscles in all parts of the body, improve physical qualities such as strength, speed, endurance and flexibility, and cultivate people's will to be brave, tenacious, cooperative and cautious.

3. The water environment is very different from the land environment. Studies have proved that people's resistance in water is more than 800 times that in air, so snorkeling helps to consume body heat and achieve the effect of losing weight.

4. In the water, it is almost in zero gravity state, which greatly reduces the pressure on joints, bones and muscles, is not easy to be injured, and the pain of exercise is also weakened.

5. People basically don't sweat when snorkeling, which reduces the irritation of salt in sweat to the skin. At the same time, the skin turns red and hot under the beating of water and waves, which dilates capillaries, improves the circulation function of subcutaneous blood vessels, and has a special massage function, which can reduce the relaxation and aging of the skin and make the skin smooth, smooth and elastic.
