1, after reading the diving safety precautions, do your homework well. Diving is not impulsive. Look at some online experiences and start simple exercises. You can ask your coach or a friend who can dive deeply.

2, check the diving equipment, a very important link before diving can not be sloppy. Confirm the equipment by yourself and give it to your peers to check it again. In order to ensure safety, diving must be carried out in pairs.

3. Get into the water, put your equipment on your back, and walk into the sea with your diving partner. Beginners who jump after backflips should not learn. When the water is waist deep, put on a diving mask first and help your partner put on flippers. After this, put the regulator in your mouth and start breathing from the second decompression part. Turn back, wipe your feet, and continue to retreat into the sea to prevent tripping due to inconvenient flippers.

4. Diving: After reaching the scheduled diving place, gradually dive into the sea along the natural slope of the underwater instructor. The first time you experience a diver, the diving depth should not exceed six meters. On the way to diving, always observe the water pressure gauge and master your own depth.

When diving, you must pay attention to releasing the pressure in the ear hole, otherwise the ear hole will feel pain. The method is to hold your nose and inhale through your mouth, then close your mouth and nose to exhaust. At this time, you will feel a "poof" in your ear, as if something is coming out. The water pressure changes with the depth, and the pressure in the ear hole should be released from time to time.

5. Move in the water. Look at the coach's gestures when diving to a certain position. You can move left and right and keep your body in the water when swimming. In order to reduce physical exertion, we should swing the flippers regularly, breathe smoothly and without tension, and adjust the buoyancy correctly to avoid collision with the seabed.

If the body starts to feel heavy, the mediation posture can also input a little air into the buoyancy regulator. Observe the surrounding environment and exchange information with diving partners.

6, drifting, if you want to drift after diving, first use gestures to tell your partner to prepare to drift, and the two should drift slowly. At this time, we should pay attention to it, and the floating speed must be slow. If it is too fast, it will cause diving obstacles because of the change of water pressure, and the body will need some time to ease because of the change of water pressure. Immediately after floating on the water surface, air is filled into the buoyancy regulator to maintain buoyancy, and a snorkel is used for breathing.

7. Go ashore, swim to the shallow water on the shore after coming out of the water, and go ashore backwards when entering the water. After landing, diving records must be made. This is a good habit that must be formed.

If you want to experience the fun of diving better, you should listen to the theoretical knowledge carefully and practice well before you go into the water. You can practice in the swimming pool. People who experience diving for the first time will be nervous. I hope it will help friends who are about to experience diving.
