What is Freediving?


Are you still unsure what freediving is?

You may have seen some cool pictures online of divers in sleek wetsuits without any scuba tanks and wondered to yourself “What is THAT all about!?” You may have a vague sense that freediving is a kind of deep mental and physical challenge, a practice, like yoga or Tai Chi, or you may simply consider it a fun way to explore the coral reefs you visit on your worldwide travels. This article will help you understand the wonderful world of freediving.

Freediving is simply any underwater activity done on a single breath of air. Rather than use tanks of compressed air to visit the world beneath the waves, we use the air we can inhale into our lungs. Anyone can learn freediving – humans are very good at it! The world record for diving deep without fins is more than 100m. That is more than the height of the Statue of Liberty!

Freediving is about relaxation and control. We need to relax both our physical bodies and our minds. More relaxation means less oxygen consumption.
In a freediving course you will learn how to relax deeply, let go and manage the sensations of urge to breathe. With a little expert training you can easily hold your breath for several minutes, and dive tens of metres deep.



We can dive deep into the ocean (Depth), we can swim underwater for distance, horizontally in a swimming pool (Dynamic), or simply lying face down in the water, motionless, holding our breath (Static). In a good freediving course you will practice all these forms of diving.

How we perform the depth and dynamic dives also varies, with different ‘disciplines’. We can pull down a dive line with our arms only (FIM, Free Immersion), we can swim down using bifins or a monofin (CWT, constant Weight) and we can swim down and back up using only the power of our arms and legs (CNF, No Fins).

Freediving has many different forms and applications:



Freediving is a sport unlike any other in the world. In competitions, athletes compete with each other to dive the deepest or the longest, but recreational sport freediving is less often seen as a competition against others and more as a personal challenge with oneself. Especially in deep freediving, we train our bodies and minds to achieve depths we previously thought impossible.


Personal Development & Health:

The pursuit of new depths in freediving requires us to have a well-balanced fitness and strength in the body, a stable and resilient nervous system and a mind characterised by mindfulness and equanimity. Developing these qualities generally results in a healthier and happier person.




Your freediving skills can be used to explore coastlines, coral reefs, shipwrecks, underwater caves and much more. As a quiet and graceful visitor in the ocean you can more easily interact with the creatures that call the sea their home.


Underwater Photography:

Incredibly popular these days, photography while freediving means you can easily slip beneath the surface and get great pictures without all the equipment, costs and nosiy bubbles of scuba gear. Another advantage is that the fish and other sea life are less disturbed by the freediver and more likely to approach and join in the fun!



Hunting & Harvesting:

For tens of thousands of years freediving has been a means for humans to hunt and find food, whether that is chasing a fish with a speargun or harvesting seafood like urchins. Although controversial, there is no denying that hunting for one’s own food is the most sustainable means of surviving from the sea.


Environmental Protection:

We can use our skills as freedivers to help keep the ocean clean. We can remove old fishing nets and do our part to reduce the tsunami of plastic waste flooding into the sea every day. Every little helps.


Is freediving dangerous?

Freediving has often been called the most dangerous sport in the world, but this is simply untrue. In the past 25 years only one freediver has died in competition. While it is indeed true that many people die each year while spearfishing and snorkelling, there is a simple reason for that – diving alone. Freedivers who run into problems when diving alone and black out, are unlikely to survive. On the other hand, a diver who dives with another set of eyes on them, after having learned the safety guidelines and rescue techniques of a freediving course, will be safe from harm.
When done with the knowledge and skills you will learn from an experienced instructor, freediving is probably the safest ‘extreme’ sport.
