For some people, maybe diving hundreds of meters into the ocean floor with just one breath and without using any breathing aids is impossible. If some people think that this is indeed possible to be done, then the next question that will arise in their minds is what kind of crazy person would want to do that. But for some others, it is a sport called free diving or freediving, even more than just sports, it is a way of life and a way to communicate with nature.

Freediving or free diving under the sea without using breathing aids makes us humans enter the most inhospitable nature or environment and feel life in the world, where only a few people do it.

Freediving is an international sport

Buchner's achievement was the starting point where freediving became modern sport. The International Association for Development of Apnea (AIDA), a body that takes care of records and forms rules about various disciplines of apnea or breath holding. Apnea includes holding the breath statically including freediving so some events of apnea are often done in the pool.

Most disciplines in diving take place at sea, where divers must compete to reach the deepest point they can reach before finally returning to the surface safely. Divers determine the target depth they will achieve before the competition starts. Then the diving rope is lowered according to the specified depth. After that they tried to reach this depth with one breath. If they succeed in achieving it, then they must take a marker that is placed on the ballast at the end of the rope and then back to the surface. How they do this depends on the discipline they follow. The most challenging and seen by many as the purest form of freediving is Constant Weight No Fins (CNF) or diving without using fins. Within the CNF, divers must descend with their own strength according to the existing rope path, they must maintain their weight and cannot release the ballast they use to return to the top easily. By the time they have reached their depth target, they are only allowed to touch the rope once to rotate and return to the top. CWF's world record is currently held by William Trubridge from New Zealand with a depth of 101 meters.
