2. what are the types of diving?
In modern times, diving has been widely known. Many people's first reaction when they hear about diving is to swim on the seabed with a bulky oxygen cylinder. In fact, this type of diving is called "deep diving", also known as "scuba diving", which is a branch of diving. Diving is generally divided into three categories: snorkeling, deep diving (i.e. scuba diving) and free diving.
Snorkeling
The equipment is light, with a face mirror + breathing tube + fins. The simple explanation is that the body floats on the water and is buried head down into the sea to see various underwater scenery. With low difficulty and high interest, snorkeling can be carried out in almost all waters, which can be regarded as the basic configuration of various island tours. People can choose this one if she wants to have a try.
Deep diving (scuba diving)
Deep diving, also known as scuba, is the heaviest equipment. Diving with its own underwater breathing system, to put it simply, requires launching with buoyancy adjusting device (BCD), gas cylinder, gas cylinder valve, back frame, regulator and pressure gauge (SPG).
Unlike snorkeling near the water surface, deep diving usually needs to descend to a depth of tens of meters, which can deeply explore the mysterious underwater world.
Free diving
Diving without respiratory system through the regulation of vital capacity is difficult and belongs to extreme sports with great risk. It is one of the motivations for many girls to learn how to dive freely without carrying heavy equipment and being able to wear a sexy and beautiful bikini to shoot a large film at the bottom of the sea.
However, free diving is a serious test of physical fitness and professional knowledge. It can only be tried after systematic teaching and repeated training. After all, although the underwater world is beautiful, your life is more beautiful.
If you just want to feel the feeling of diving, you can choose snorkeling. Most islands have professional coaches who can hire guidance. But if you want to go deep into the sea, watch the more beautiful ocean world closely, and swim with the sea elves, then choose deep diving or free diving, but remember that you must learn to graduate before you go into the water.
