What is Scuba Diving?
Sep 01, 2022
Scuba Diving (Self-Contained Underwater Breathing Apparatus, abbreviation: SCUBA) refers to the diving activities carried out by divers with underwater breathing systems, allowing people to breathe continuously in the water and enjoy a leisure sport like swimming like a fish.
Because of the need to carry and operate equipment, scuba diving requires the same educational training as learning to drive and is taught by a qualified instructor who must also be a registered member of one or more international certification bodies for divers.
Basic Diver training requires the acquisition of skills for safe activities in an underwater environment, including procedures and skills in the use of diving equipment, emergency self-help and rescue operations, dive planning, etc. Upon completion of the course, a Qualified Diver certification is obtained.
Several internationally certified organizations offer diver training courses, such as PADI, SNSI, etc. After passing the certification, a "Diving CertificationCard," also known as the C-card, will be issued.
Types of Scuba Diving
They can be divided into recreational, technical, and industrial diving.
Recreational diving is usually done in an open tourist area, at a depth of fewer than 40 meters, and requires a dive buddy to look after each other.
This refers to challenging diving activities, such as diving at depths greater than 40 meters, underwater caves, shipwrecks, and other professional diving expeditions. A single person may also do it.
Diving activities of industrial nature, such as underwater engineering and marine industry.
Notes on Scuba Diving
1. Unlike freediving, scuba diving requires a lot of equipment, known as the three treasures of diving - goggles, snorkel, and flippers, which are also used for snorkeling. Buoyancy adjustment device (BCD), air cylinder, air cylinder valve, rebreather, regulator, and pressure gauge (SPG) are specially designed for scuba diving.
2. BCD is a piece of critical equipment, especially rented and idled for a few months without use. Please check carefully. Whether the flushing exhaust works well, whether the medium pressure tube can be quickly removed, there is no raw feeling, or whether the inflatable twist is flexible and works well. Whether the internal adhesion, internal bonding, or decisive change.
3. Develop a dive plan. You must understand the dive site and create a good time and depth. Headwater down, downstream back. Gas margin, how much is left to start rising water?
4. Always pay attention to the cylinder air pressure promptly to the dive guide signal.
5. Do not touch or tease marine life.
6. Do not quickly rise or fall. Follow the rhythm of the dive guide.
7. Always do the ear pressure balance, do not wait for the ear pain and then do.
8. Pay attention to your computer table (if you bring, not bring the best with) called and Kaspersky as miserable time means you have trouble
9. Randomly add more time, increase the depth is to die.
10. Single leisure bottle into the decompression do not panic, watch the table to do a stay, and then five meters to stay more will do, the shore to suck oxygen, no big deal.
