How Much Do You Know About The 7 Types Of Free Diving

Knowledge

The depth and time limit that a freediver can reach depends on the type of free diving he is training. To understand the depth and time results of free diving, you must first know the different types and rules of free diving.

Static apnea diving: time-type free diving Static Apnea-STA

In static apnea, the diver tries to keep his face submerged in the water. Static apnea is also the only type that judges freedivers based on apnea time. When the diver immersed his face, his nose and mouth were underwater. Try to stay still, save oxygen and extend the apnea time. Static apnea is almost entirely a psychological challenge. The diver has to fight the desire to breathe for as long as possible. In addition to its own challenges, static apnea is also helpful for other types of free diving training.

Most freediving students learn static apnea first, which helps them prepare for other types of training.

Swimming pool dynamic diving (fins/bare feet): distance free diving Dynamic Freediving-DYN/DNF

During dynamic diving, the diver swims in a horizontal direction and swims as far as possible in a single breath. Dynamic diving includes barefoot diving and fin diving, the most common is training in the pool.

This is a type of free diving that combines swimming, breath-holding techniques and mental control. Dynamic swimming pool diving is very suitable for divers who do not have a deep diving environment and want to train in winter.

Free Diving: Deep Free Diving Free Immersion-FIM

Freestyle is a type of free diving that challenges divers’ diving depth. Free-handed free diving divers use the guide rope to dive, without fins or any other propulsion equipment when ascending. Novices in freediving will find this kind of free-handed free diving to be the most enjoyable, because its ascent and descending skills are very simple, and it is easy to control speed and ear pressure balance.

Constant Weight Barefoot Diving: Deep Free Diving Constant Weight No Fins-CNF

Most freedivers think that constant weight barefoot diving is the purest free diving. When diving with constant weight barefoot, divers only rely on their muscle strength and swimming skills to dive, without touching the vertical reference rope or using counterweights to descend. This form of free diving may be the purest, but it is also the most difficult because it consumes oxygen fast, and compared to other forms of free diving that use guide ropes or fins, constant weight barefoot diving is much slower. Divers who pursue constant weight barefoot diving must diligently train the perfect coordination of propulsion, balance, technique and buoyancy.

Constant weight fin diving: deep free diving Constant Weight-CWT

Constant-weight fins divers use fins to dive to the deepest depth. fins can be divided into standard free diving double fins and single fins. The diver can touch the vertical reference rope only when he stops diving and starts to ascend.

Constant weight fin diving is the most common type of free diving, and it is also the most popular item for freedivers. Swimming with strong fins underwater is not only an incredible experience, divers can also stop kicking when they dive deep enough and go directly to free fall. In fact, constant weight free diving comes from fishermen who hunt fish and is the deepest depth that can be reached in the current competition.

Variable Weight Free Diving: Deep Free Diving Variable Weight-VWT

Variable-weight free diving uses a counterweight attached to a vertical reference rope to tow the dive at extreme speed, which allows professional free divers to descend to the deepest depth without wasting oxygen when diving.

Ascend you can swim or hold the rope. Variable-weight free diving is sometimes quite dangerous, because rapid descent can cause pressure balance difficulties, and sometimes divers descend to a depth greater than they can ascend. For these reasons, the minimum requirement for variable-weight free diving is advanced free divers, and they are excluded from competition.

Unlimited diving: deep free diving No-Limits-NLT

Unrestricted diving is the most extreme type of deep free diving. The diver quickly descends through ballast (such as counterweights), and then uses inflatable lifting bags, balloons or other buoyancy equipment to ascend. Neither diving nor ascent requires swimming, which makes unrestricted divers dive deeper than other types. Unrestricted diving is also the most risky type of free diving, because divers have to return to the ground safely with their own equipment after descending to that depth. Whether you are a diver or a non-diver, you may have learned about unlimited free diving from a series of unlimited free diving competitions in the world-famous “The Big Blue”. In fact, unrestricted free diving is currently not allowed to participate in competitive competitions.

Freedivers dive for goals such as time, depth, or distance, but this depends on the type of diving and its rules, and many divers can strive for excellence in all types. Free diving novices try different types under the guidance of the coach, and then decide which direction to pursue.
