In the diving hall in the city's swimming pool.

The beautiful diving professional instructor patiently taught the diving course in front of our students.

"Today, I'm here to share with you the introduction of diving basics and precautions!" , The beautiful diving instructor gestured softly with a jade hand gesture.

The words are light and sweet, mellow and pleasant, and the voice is pleasant.

…………

"Question 1: What is Scubadiving, commonly referred to as 'diving'?"

Scuba diving

(English: Self-ContainedUnderwaterBreathingApparatus, abbreviation: SCUBA)

Refers to the diving activities carried by divers with their own underwater breathing system.

"Scuba diving is generally divided into recreational diving, technical diving and industrial diving", the diving beauty instructor is very professional, and she has spoken a lot of professional terms and English words, and her voice is also beautiful and pleasant.

…………

"What we usually call scuba diving generally refers only to the scuba diving part of recreational diving."

"Recreational scuba diving is a dive with an air tank on your back, usually to a depth of less than 30 meters."

"Recreational diving is different from snorkeling on the surface, and it is also different from technical diving at a great depth with several cylinders on your back."

The instructor explains the basic course.

No. 1 also immediately understood that diving alone is a course with a wealth of knowledge and skills.

…………

…………

"Scuba diving, theoretically, you don't need to know how to swim."

"Scuba diving, you can wear professional diving equipment and have a special buoyancy adjustment device (B.C), so even if you can't swim, you can enjoy diving and get a diving license."

"But! Swimming can help you better adapt to the environment in the water, so if you can, it is recommended that you learn to swim. ”

At this time, the beautiful diving instructor said, explaining the difference between swimming and diving and the common relationship.

…………

The trainees listened patiently.

There were times when we didn't pay attention to the lectures and felt bored.

But when you go to society, you have a lot to learn, especially those related to work and many things.

At this time, I realized that many things need to be studied professionally.

Just like many basketball players often go to college, IBM and so on.

…………

…………

"Students~ Question 3: 'Do I need to get a license for diving'?"

"If you don't have a license or don't have a license and want to dive, it's Discover Scuba Diving (DSD)."

"It's an instructor-led diving experience in the sea. The depth usually does not exceed 12 meters. ”

School flower: Uh-huh~ Diving teacher~ We are here to take the diving qualification certificate.

The beauties next to them nodded one after another.

The dive instructor smiled.

Any lesson can be boring at times, but it can be made more interesting through the interaction between the students and the teacher.

…………

…………

"If you want to go to various dive sites and dive freely with the guide, instead of being led into the water by the instructor hand in hand, you must get a diving license."

"There are different levels of diving licenses, which include different knowledge and skills."

"So, the students present, I hope you will study hard and get your diving certificate", the beautiful diving instructor showed a sweet smile and a beautiful fair and tender face.

…………

…………

At this time, No. 1 opened the live broadcast room of the system.

Barrage in the live broadcast room.

Conscience anchor, welfare!

…………

"Continuing with our course, question 4 "What is the level of diving license?"

"The first level of the diver license is called the Open Water Diver (OW or OWD), and after obtaining the OW license, you can dive in open water at a depth of 18m."

The course after OW is called Advanced OpenWaterdiver (AOW or AOWD).

…………

"Divers with AOW certification can dive at depths of up to 30m. The usual recreational diving is at this depth. ”

"AOW is followed by Rescue Diver, Divemaster, and other specialty courses to choose from. Different levels of certificates have requirements for the number of diving cylinders, that is, the number of dives. ”

"It should be noted that getting the corresponding license at the end of each course does not really mean that you are a diver of this level."

"What's more important is to increase diving experience after the course and digest this knowledge in order to become a truly qualified diver."

…………

"Diving is an activity that requires a lot of knowledge and skill, and the better the technique, the more fun you will have underwater."

"If you want to dive for a long time in the future, the recommended courses to take are OW, AOW and Nitrox, which can be completed and can be used on diving trips abroad without too many restrictions."

…………

…………

Question 6: 'Is it possible to dive with myopia?' Can I wear contact lenses when diving? ”

"It's okay to be nearsighted, and you can wear contact lenses while diving. People who are nearsighted and do not wear contact lenses can also buy a mask with a prescription. ”

…………

"Question 7: 'Can a woman go into the water during her menstrual period?'"

The answer is yes. Tampons can be used. Just keep warm after getting out of the water and don't catch a cold. ”

The beautiful students looked at each other, and Qin Shou nodded.

…………

"Question 8: 'I once dived in a certain place, but my ears hurt so much that I don't know if I'm not suitable for diving.'"

"It's a topic that I hear a lot," says the beautiful diving instructor.

"The pressure of the water is created under the surface of the water, and 10m increases the pressure by one atmosphere. Even in the pool at a depth of more than one meter, sensitive people will feel the sensory changes in the eardrum. ”

…………

"This is normal. Diving ear pain is caused by the pressure of water pressing on the eardrum, and the eardrum and the surrounding muscles are pulling. ”

"Just do a simple equalization of ear pressure and you won't feel pain. This action, it stands to reason, whether it is a diving course or experience diving, the instructor should be taught. ”

…………

…………

"Question 9: 'What is freediving?'"

"Free-diving is the activity of diving without carrying underwater air supply equipment, with a single breath and breath holding."

"Freediving includes freediving for fun, experience, photography, hunting, and extreme breath-holding dives for competitive purposes."

"To put it simply, diving without a tank and just one breath is freediving. In the same way, freediving for us people only refers to recreational freediving, not competition. ”

…………

"Freediving is also divided into different levels of courses, different levels, practice at different depths, the higher the level, the greater the depth, and the higher the skill requirements."

"The best freediving associations are SSI and AIDA, and SSI has developed Chinese freediving teaching materials. To learn freediving, you need to find a professional freediving instructor. ”

…………

…………

"Question 10: 'How are underwater photographs taken?'"

The beautiful diving instructor said: I believe that everyone has also thought about taking beautiful photos in the beautiful ocean.

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

"First: the camera itself is directly waterproof

Second: ordinary cameras are equipped with a special waterproof case for the camera. ”

…………

"Directly waterproof camera, the advantages are"

"First: small size, light weight, easy to carry

Second: Don't worry about the waterproof case in case of water leakage and damage to the camera

Third: the operation is simple and convenient. ”

The beautiful diving instructor took a sip of the fitness energy drink and continued.

…………

"The disadvantages are:

First: the waterproof depth is limited

Second: limited imaging quality

Third: it is inconvenient to install external equipment"

"Therefore, the camera that is directly waterproof is more suitable for snorkeling players and deep diving players who are just getting started."

"If you want to get better imaging results, you still need a better camera with a waterproof case."

"Now, whether it is a card machine, a mirrorless or a professional SLR camera, there are professional waterproof shell manufacturers to produce supporting waterproof shells. The price of a good waterproof case even exceeds the camera itself. ”

…………

…………

"Question 11: 'Where can I learn to dive'?"

"Two tips for learning to dive:

First, you must learn in the open water, that is, in the ocean.

Second: You can consider going to Kenting, Taiwan to learn diving. ”

The beautiful diving instructor said.

Everyone listened patiently.

Number One touched his ear.

The beauties are looking with their beautiful eyes open, and their long beautiful eyelashes are flickering.

…………

"Basically, every dive shop in Shanghai will offer diving courses, that is, you can learn to dive. In the big cities of China, there are now inland dive shops. ”

"Most of the teaching in inland dive shops is taught in swimming pools, and the better ones are only taught in deep still water pools, such as diving pools."

"Diving in the pool, feeling and feeling, is completely different from learning in the ocean."

…………

"You can't feel the currents, the waves, these dives are really feeling, and because of the depth limit, the site is limited."

"Many dive shops teach the basic movements of diving in the OW course, as well as emergency handling procedures, etc."

"It's far from enough, and this also buries hidden dangers when students actually go to sea to dive in the future." The beautiful diving instructor said.

After the basic course, he took a sip of energy drink and said to the students with a smile, "What did the students learn in tonight's course?" ”

…………

The students nodded their heads one after another, clapping rhythmically and lovingly.

After all, it's hard for teachers to teach so much.

It's just that in many cases, the more interesting the teaching is to teach, the better the chemistry and happiness it will generate.

Of course, professional courses can also greatly improve the level of professional knowledge and skills.

At this time, the professional diving basic course is explained.
