About Us

PureFreedive are a group of competitive and recreational freedivers in the Nottingham and Sheffield area of the UK. Our collective purpose is to enjoy our fascinating sport and to share it with others.

To freedive you need determination, positive attitude and an open mind. As a freediver you will learn about your own body, mind, psychology and possibly even your spirituality. You will learn to enjoy our oceans and interact with marine wildlife in the most natural and amazing way. Most of all though, you will develop trust in and friendship with your freediving partners in the same way people have done for thousands of years.

Our instructors travel in the UK and abroad to run courses and personal training for dive centres, sports clubs, charities, universities and team building events. Taking both a scientific and holistic approach is central to our diving philosophy; learning from dive theory, ancient meditation techniques, yoga disciplines and modern sports science in one's own personal proportions is key. People are all different and all have a slightly different outlook and approach to freediving. PureFreedive know this and want everyone to learn at their own pace and within their own boundaries and ethics.

Aida 1 Star 3m-10m depth

Aida 1 Star

No matter what your background in diving is, the Aida 1 star freediving course will open your mind to a whole new underwater experience. You will learn the basic theory of freediving and how to prepare yourself for a breathold dive including breathing, duck dives, finning, dive theory, buddying, dive times, safety and rescue techniques. This course is ideal for those wishing to free dive around reefs or coastal areas in around 6m to 10m of water. Aida 1 star is not based around competitive disciplines and there are no depth or time requirements to meet.
We run our 1 star programs in a deep dive pool, inland lake or the sea with the expectation of everyone comfortably reaching depths of 6m and deeper.

Aida 2 Star Freediver, 10m-20m depth, 2min-2:45min Breath hold, 40m-55m dynmic

Aida 2 Star

This is probably the most challenging and rewarding of the Aida courses and an ideal starting point if you are already confident in the open water. The course builds a solid foundation of good technique and safety so that you can buddy with other Aida 2 star freedivers anywhere in the world. This course consists of two or more theory sessions, a dry breathing session, two or more pool sessions and three open water dive sessions.
Although the course contains some element of building competitive discipline performances the real goals are in teaching safety and enjoyment. In the UK we run our 2 star courses in 25m heated swimming pools and inland dive sites like Dosthill and Capenwray.
To gain the Aida 2 star freediver certification you will have to perform a 2 minute breath hold, swim 40m underwater horizontally with fins and dive to a depth of 16m in open water. These requirements are obtainable by the average person and most 2 star students are amazed by what they can achieve with a little coaching. If you are only interested in pool freediving then this section of the course can be done on its own. There is no pressure to pass all parts of the certification during the course, you can allways complete any outstanding requirements later.

Aida 3 Star Freediver, 20m-30m depth, 2:45min-3:30min Breath hold, 55m-70m dynmic

Aida 3 Star

Interested in going deeper and improving your technique? This course goes into the theory of freediving in more detail giving you a greater understanding of the physiology and techniques behind deeper diving. You will improve your freediving performance and advance your safety and rescue skills. This course consists of three theory sessions, two pool sessions and four open water sessions. Aida 3 star will show you how to improve your freediving performance and build a personalised training plan. At this level you will start to look at freefalling at depth and build on your relaxation and breath hold techniques.
To gain the Aida 3 star certification you will have to perform a 2 minute 45 second breath hold, swim for 55m horizontally underwater with fins and dive to 24 meters in the open water.

Aida 4 Star Freediver, 30m-38m depth, 3:30min-4:00min Breath hold, 70m-100m dynmic

Aida 4 Star

This course takes you to a whole new level in your freediving. Not only will you learn the latest techniques for deeper diving but you will learn much more about conditioning your body for Freediving. This course will push you to the limits of your Freediving abilities. The Aida 4 star is the highest level a recreational freediver can achieve. Course content consists of three theory sessions, two pool sessions and four open water dive sessions. To gain the Aida 4 star certification you will have to perform a 3 minute 30 second breath hold, swim 70 m underwater with fins and dive to 32 meters in the open water. Aida 4 star is a prerequisite for taking on the exceptionally tough demands of the Aida instructor course.

What Is Freediving ?

Freediving, or apnea as it is also now known, is the ancient art of diving on one breath of air. Humans possess physiological systems to allow them to breath hold dive to depth. Our heart rates slow, our oxygen consumption goes down, blood is drawn away from the limbs and into the core and our lung volume can reduce in size when compressed at depth. We can consciously control our breathing and even control our heart rate with training. Brain activity can be reduced through mediation as has been done for thousands of years by practitioners in the east. Regardless of the whys and hows it is a fact that we all have these abilities, we just need to wake them up and we become freedivers !

The media widely publicise record breaking death defying plunges into the abyss and the unspeakable demands this makes on the human body. Unfortunately this is the general perception of freediving even though very few people dive at this sort of level. Those that do are highly dedicated and train full time, but you really don't need to push the limits to enjoy freediving. The truth about freediving is you dont need to be an olympic athlete or have the figure of a supermodel!

We really believe that freediving is about being at peace in the water and enjoying the wonders that you will find there. That's not to say that we don't deep dive, we do, but we don't chase numbers just for the sake of it. We believe if you're not smiling when you surface from a dive then you're doing something wrong.

A person's style of diving reflects their personality and psyche, and as such everyone has a slightly different interpretation of what freediving is all about. For some it is about personal sporting challenge, others are interested in the deep meditation and spiritual side of things and some just like the freedom of swimming about with the fish and enjoying the wonders of the underwater world. At PureFreedive we like all of this, but foremost we value the human experience of our shared endeavours on this beautiful planet.

Never try any form of freediving without attending a recognised course. Never freedive alone and never ever hold your breath in the bath.


Aida is the international association for the development of apnea. It is a non profit making organisation run entirely by volunteers. Aida only deals with freediving and isn't involved with scuba diving or equipment and documentation sales. It is run by freedivers for freedivers and all certification fees go directly into the development of the sport.

Being free from profit making objectives gives the organisation the freedom to work solely for the benefits of divers and diver education. All national and international freediving records and safety requirements are overseen by Aida.

All Aida instructors have to demonstrate extremely high standards in all practical and academic areas before being certified to teach.

Constant Weight With And Without Fins

The freediver desends and ascends a line under her own power without changing her ballast; only a single hold of the rope to stop the descent and start the ascent is allowed. Constant weight is a popular competitive discipline and is one of the three disciplines in international competitions, static and dynamic being the other two. Dives are made with either mono-fins or bi-fins with the monofin divers making the deeper dives.
CNF is constant weight diving with no fins. This is diving using a modified form of breast stroke and requires high levels of coordination and concentration. We think CNF is the purest form of free diving and as such we like it very much !


Dynamic Apnea With And Without Fins

The freediver travels in a horizontal position under water attempting to cover the greatest possible distance. Any propulsion aids other than fins or a monofin and swimming movements with the arms are prohibited. Competition performances are only recognized in swimming-pools with a minimum length of 25 meters and are sometimes combined with static apnea in indoor competitions. Trained swimmers can take to DYN with astonishing results with a competent butterfly stroke soon becoming a powerful monofin technique.
DNF is dynamic apnea without fins. This like CNF is a very pure form of freediving and we like it a lot. Many people find DNF easier than DYN because they are so used to swimming breast stoke.


Free Immersion

The freediver dives under water without fins, descending and ascending by pulling on the rope. Descents are made head first or feet first depending on the diver's equalization ability, some divers even use both. Free immersion is a different dive experience and for many their favourite, it has to be experienced to be understood !


Static Apnea

The freediver holds their breath for as long as possible with their face in the water so they can't cheat. It is very much a mind game and requires the ability to control your thoughts and keep your heart rate low. Trained freedivers can slow their heartrates to below 30 beats a minute and switch their minds into a trance like state. These relaxation techniques are important for all forms of breath hold diving so static is considered important by many freedivers, ourselves included.
Static apnea is the only time discipline and one of the three performed in international competitions, with constant weight and dynamic with fins being the other two. Performances can be done and recognized in both pool and open water (sea, lake, river, etc).
Under no circumstances should anyone try this or any other form of freediving without training. Never freedive alone and never ever hold your breath in the bath, attend a recognised freediving course.


Variable Weight

The freediver descends with the help of a ballast weight or sled and ascends under his own strength using arms and/or legs, either pulling or not pulling on the rope as desired. Variable weight diving is the discipline featured in the cult film 'The Big Blue' although things are done a bit differently today! This type of diving requires advanced skills and expert supervision. We only use variable weight dives for training at PureFreedive and do not pursue it as a discipline in its own right.


No Limits Freediving

The freediver descends with the help of a ballast weight and ascends via a method of his choice. No limits is the absolute depth discipline. Going down with a sled, and going back up with a balloon, a diving suit or a vest with inflatable compartments, or any other means. We do not practice no limits freediving at pure freedive, but if you are interested we can suggest some options for you to explore.

History Of Freediving

There is archaeological evidence of freediving at least three thousand years ago. This isn't surprising, put any child in a swimming pool and they will want to swim to the bottom. But then this isn't surprising either as we all spend the first nine months of our lives suspended in water. It does seem plausible that as long as man has been able to swim he has swam under water holding his breath.

There are records of enterprising chaps charging navies and shipping companies handsome sums for retrieving items from depth. In fact it is only in recent times that scuba divers managed to go deep enough to put these guys out of business. There are still freediving communities in the world, the Amas are Japenees and Korean female divers who still use traditional diving methods at least two thousand years old to harvest the sea.

Around 1950 the modern sport of freediving was formed and people have competed ever since. Techniques have changed and depths have increased as men and women have pushed back the boundaries of human achievement. Today freedivers have been to 126m with fins and a staggering 101m without fins. No limits sled divers have now been to 214m, thats 214m on one breath of air !

Today recreation freediving is growing fast. Scuba diving for fun has been with us since Jacques Cousteau invented modern open circuit scuba and opened up the oceans for exploration. Talk to freedives who also scuba and they will tell you the two are very different. The silent undersea world of the breath hold diver is a very different place and even seasoned tech divers are captivated by its appeal.

As children we are taught to behave and swim on the surface when the true wonders are below it. All it takes is a little knowledge and practice and a whole new world opens up. We want more people to gain the knowledge and ability to enjoy freediving as much as we do.
