Can you dive if you can't swim?
Can't swim to dive.Diving is the kind of travel diving with oxygen cylinders. It is possible to go to the sea as long as it is simple training. The premise is that there are no restricted diseases, such as hypertension of heart disease.Before diving, there will be a coach to teach you, and the process is very simple. You only need to master a few basic actions and gestures.
Types of diving
The submersible is divided into: hard diving, soft diving, semi -closed lock circuit air supply type, should be delivered, and self -sufficient air.
Divided by diving: non -saturated diving, saturated diving; types of breathing gases: air diving, nitrogen, hybrid gases (artificial air diving), mixture, oxygen mixed gas (artificial air diving), hydrogen, oxygen mixed gas (hydrogen, oxygen, mixed gas (Artificial air diving), other hybrid gases.
What are the Diving equipment
1. Facial mirror
The diving mirrors on the market now are mainly divided into three types: silicone, rubber, and PVC; rubber and PVC materials generally have some odors. The rubber material has rarely appeared in the leisure market. Generally, a few diving mirrors are made of silicone materialsIt is non -toxic and tasteless. The price is slightly more expensive than PVC, but it is softer, more durable, and more comfortable to wear.
The appearance is mainly divided into dual lenses and single lenses. There are no differences in these two uses, and the field of vision is similar. The advantage of dual lenses can be equipped with close -up lenses; the selection is mainly based on whether it meets its face shape and personal preferences; there is another kind of one; there is also one is that there is one.Fullface mask; Full mask, the design of this type of mask makes the divers not have to include the respirator in the mouth and combine the communication interface, mainly to enable the diver to achieve underwater calls; mostly for engineering diving.
2. Breathing Tube
The material of the respiratory Tube is also mainly divided into silicone, PVC, which is better for silicone tubes; structures are divided into all-dry and non-dry type;It is welcomed by junior players to prevent water from entering; but from a practical perspective, it is still a traditional non -dry respiratory Tube with simple structure and smoother breathing.
Buying note: The choice of respiratory Tube must meet the principles of ergonomics and mechanical design. The diameter size and length must be appropriate to facilitate drainage, and the design of the water stop valve must be available to prevent seawater from pouring in.The part of the bite should be the best choice for bite comfort.
3. Cold -proof clothing
Cold -proof clothing, also known as diving suit.It is mainly divided into wet, semi -dry, all -dry, wet type divided into 3 mm, 5 mm, 7 mm and other thickness.Wearing semi -dry and full -drying potentials, you can keep your body not wet, and you can also wear warm clothes in the interior. The insulation effect is the best.The choice of diving coats is mainly determined according to the water temperature of the diving environment; tropical or temperate waters, 3 mm thick wetwear are the most commonly used; the lower the water temperature, the thicker the need to choose a divingSemi -dry or full -drying; all dry clothes can even achieve under ice diving.
Buying note: In order to achieve the effect of preventing the cold, the cold -proof clothing must be fitted, soft, easy to unload, and not easy to deform, and does not affect the ability of divers to move.Secondly, choose the tricks you like.detailed
How to achieve ear pressure balance when diving
1. Pin the nose and breath.Ear pressure balance refers to the same techniques that make the pressure in the ear the same as the surrounding environmental pressure.Generally, the more commonly used way is to pinch the nose and drum, pinch the nose, block the nostrils, and gently breathe with the nose. At this time, you will feel that the eardrums are swollen and giggled.
2. In addition to the method of pinching the nose, you can also reach the ear pressure balance by swallowing the mouth, yawning or swinging the mandibular mandibular.

5. Headache
The reason may be inadequate blood supply to chronic rhinitis, water or body cold, temporary cerebrovascular spasm.At this time, you should go ashore quickly. Use your thumb to press the top of the head, the sun and the lack of acupoints, and then apply it with a hot towel, and drink a cup of hot boiling water to improve.
6. Abdominal pain blocked
Just after eating or diving on an empty stomach can cause abdominal bloating.At this time, you should go ashore to lie on your back, press the tip of the toe to the middle courtyard, go to the courtyard or Zusanli, and take 3 to 5 ml of water at the same time at the same time, and apply the abdomen with a hot hand towel.
