The practice of freefall in freediving occurs when a free diver reaches a point of negative buoyancy and stops finning or swimming downward, allowing the force of gravity alone to draw the diver deeper.
As a free diver descends in water, the volume of air inside of their body (therefore the volume of the body itself) becomes smaller or more compressed thereby changing the buoyancy of their body. This is explained by Boyle’s Law and Archimedes’ principle respectively.
Every free diver possesses a different degree of buoyancy which is variable to their freediving gear (i.e. wetsuit, weight belt, fins, mask, etc.). A safe freediving practice is to have a positive buoyancy of at least 10 meters because most of the blackouts happen between 10m and the surface. This way, if a blackout does occur, the diver will float to the surface, making a rescue more achievable. We will discuss more safety protocols in a different blog post.
The freefall is a technique used by almost every professional free diver. This is because, during the freefall the diver is not required to use physical exertion to gain distance in depth. This allows the diver to conserve oxygen and energy while decreasing the rate of carbon dioxide production. The freefall can be likened to a depth static, where the individual can focus her or his consciousness on relaxation and equalization.
That being said, there is a proper technique to the freefall. When mastered freefall can lead a free diver into a dream-like or zen-like state. In general, the ideal body position will be as hydrodynamic as possible. Specifically, the head should be in a neutral position to aide in equalization, neither looking down or up the line. The torso parallel to the line. The arms and hands should be streamlined along the side or front of the body. Without fins the legs should be straight with pointed feet, or slightly bent legs with relaxed feet. With fins, the legs should be slightly bent from the hips or knees so that the blade(s) of the fin(s) run parallel with the line (like in the picture).
A good technique will yield a freefall rate of approximately one meter per second (1m/s).
While in freefall the free diver has the option to close their eyes, this furthers the relaxation and therefore oxygen conservation. The current CWT (Constant Weight) world record holder Alexey Molchanov while in freefall has said he only opens his eyes slightly every few seconds. He does this to make sure he has good positioning along the line. Other divers, such as Alenka Artnik, the CWT Roatan 2017 AIDA World Champion freefalls with her eyes closed the entire time and feels the line with her hand. There are many slight variations that are a personal preference for each individual free diver.
In conclusion, the freefall is a very useful and peaceful practice to improve relaxed gains in depth while freediving. It is personally our favorite part of freediving, hence the name ‘Freefall Academy’. We hope you have learned something from this post. Please share an experience or thought with us below in the comment section. Or better yet, come freefall with us in one of our courses here in La Paz. Safe freefalls.

Espiritu Santo Island is without a doubt one of the most beautiful places on Earth. It has scenic mountain ranges reaching a maximum altitude of 1200m, extraordinary cliffs made from volcanic stone and pristine white sand beaches. The amazing water colors, ranging from green turquoise, to deep and transparent blue gives a feeling of tranquility to the soul.
It is a perfect place to experience snorkeling, freediving, scuba diving, hiking, kayaking, camping, stand-up paddle boarding and sailing.
Espiritu Santo Island is apart of the Archipelago of Espiritu Santo, which became a National Park in 2007. Espiritu Santo Island is located in the Gulf of California, North of La Paz, Baja California Sur. Furthermore, it became an UNESCO World Natural Heritage Site in 2005 along with 243 other islands, islets and coastal areas in the Gulf of California. These areas contain 39% of the world’s total number of species of marine mammals and a third of the world’s marine cetacean species.
In addition, the island contains many habitats, such as mangroves, sandy bottoms, rocky reefs, estuaries, beautiful isolated beaches and bays. It’s perfect for all kinds of people, from little kids who want to start exploring the underwater world, to experienced divers that would like to see why the Sea of Cortez is called the “aquarium of the world”.
Espiritu Santo Island has 38 species of plants and animals that are unique (or endemic) in the whole World. The juancito, the babisuri, the black hare and the sandy snake are examples. Furthermore, there are 200 species of plants and more than 70 species of animals (not counting the ones underwater).
As you submerge before the surface you can find at least 15 species of marine mammals, including dolphins, whales and the famous colony of sea lions. In addition, you can find more than 50 species of aquatic birds gracing the waters, airways and cliffs.
The Sea Lions that live in the islets called “Los Islotes” or “La Lobera” are a species scientifically called Zalophus californianus.
As well as other marine mammals, sea lions are very curious. This attitude has to do with exploration and playing. The young ones are especially playful; they might even play with your fins or other “weird” equipment. Think about a cute little puppy, then put it underwater, let it evolve and you will have a beautiful playful sea lion.
These beautiful creatures are on the island all year around. Los Islotes contain about 500 sea lions every year. The reproduction season initiates with the birth of the pups at the end of May. Continuing with the breast-feeding and mating time around June, July and August.
Don’t miss the opportunity to swim or dive with these beautiful animals in Espiritu Santo Island. Check out our tours here.Read More
