This is where all Freediving courses will start. You will sit on cushions in small groups and learn about Freediving physiology. The dive centre is located on the beach so you will have a relax view on the ocean from your classroom. They are equipped with televisions to display the course program and videos of Freedivers to analyse different techniques. The more you understand the science behind the sport, the more confident you will feel underwater. Thailand is a warm country, temperature in Koh Tao are from 25C to 35C so we have equipped the school with air conditioning, fans and showers. For relaxation and static breath hold, we use high quality 20mm yoga mats. It is almost as comfortable as your bed. In the classrooms you will also find useful Freediving toys to measure the size of your lungs or check your resting heart rate. We decorated the school with large Freediving posters and framed pictures of the main events that took place at Blue Immersion with cute notes next to it. We also use our sea view terrace to teach some Freediving theory once in a while, but it is mostly a place to do stretching or hang out.

Freediving courses always start in the pool or shallow water. It allow students to practice breathing, equalisation and swimming techniques in a familiar environment before going in the open water. Freedivers communally call the pool training: the open water simulator. During the beginner course, the pool session start with simple skills such as duck dives, turns, finning and body position. You will then start your first Freedives horizontally from one side of the pool to the other. Very quickly, your confidence will increase and you will be able to swim longer distances underwater. If you swim 40 meters horizontally, you are perfectly capable of doing the same distance vertically: 20m down and 20m back up to the surface. The only difference between horizontal and vertical Freedives will be equalisation.


Freediving is mostly a mental sport. However having a good fitness level can improve your relaxation, oxygen consumption, swimming technique and tolerance to lactic acid. For example, some of the most popular Freediving exercises: Apnea cycling and Apnea squats. All students are welcome to have a workout. We have a stationary bicycle, a bench press, a squat machine, a pull up bar and an abs bench. Our little Freediving workout room has the sea view and will be get bigger next year. The gym is very helpful in the Master course. When you are off diving, you can build more strength in your legs and make yourself a stronger swimmer. Freedivers who are limited by the urge to breath or/and burning legs during dives can rapidly fix this problem on the bike with Co2 tolerance and lactic exercises. Freediving workouts are healthy and fun!   


A nice set up is essential to practice Freediving safely! Freedivers must have access to training dive sites comfortably to be 100% rested before their dives. The boat need to be back on shore without transferring Freedivers to another boat in case of an emergency. Those of you who knows Freediving understand that we feel much more confident if we know that our safety is guarantee. We Freedive Koh Tao with a catamaran built and designed especially for Freediving trips and depth training. Our boats bring students from dive sites to shores. It is equipped with two competition arms that allow an easier descent and ascent for our advanced divers. It allows us to train variable weight and no-limit disciplines if we attach our sled on it. We have access to most dive site within 10-15 minutes. Catamaran are extremely stable which really minimize the risk of seasickness compare to local boats or speed boats. The Blue Immersion vessel is simply a Freediving platform with a small engine that use a very small amount of gasoline. It makes our school the most well equipped and safest in Thailand!


Our outdoor seating area is a great place for our Freedivers. We use it for stretching, meditation, lunch and to hang out after the training is over. Our early morning stretching/meditation sessions are important for Freediving. It allows our students to gain thoracic flexibility rapidly and achieve greater depth safely. Eating healthy food is a boost for Freediving. Our body gain endurance to low levels of oxygen and allow us to hold our breath much longer. You can enjoy Freediving with us without feeling bloated. Sandwiches, salads, Thai dishes, vegetarian/vegan food and snacks are available. After the training, we might also enjoy some cold beers looking at the sunset.


After you have tasted a little bit of Freediving at Blue Immersion, there is a big chance that you get addicted. You might think of buying your own equipment, so that you can indulge in your new addiction whenever you have the opportunity in holidays or during your day off at the pool. In our shop, we sell masks, snorkels, fins, wetsuits and various diving accessories. Because no size fits all and everybody is different, we will advise you on the equipment that suits your personal goals best. To experience Freediving there is nothing like being comfortable in your own equipment. Your own gear will give you a greater mental boost, feeling like a badass, you will achieve greater time, length and depth!


Freediving is not a difficult sport to learn, it can be done by almost anybody. In order to make the education easier, you will get all the theory and some equalisation exercises after your reservation. Studying before your training will give you more time to practice Freediving skills during the course. The theory can be done on your smart phone with the SSI or Molchanov application. On those apps you will find lots of amazing features such as videos of Freedivers, your theory manuals, your certifications, a map that shows where you can find other Freediving schools and instructors. The apps also include feeds where students can share comments and pictures of their own Freediving experiences. On the Molchanov app you will get the free base training option. It is a training program for each Freediving disciplines to keep progressing after your course. This online coaching system is updated every week. You simply need to find other Freedivers in pools or oceans to train and do your safety.


Come to play at Blue Immersion! Before or after training we are hanging out in the school and do breath hold games. We like having students around all day long. You can read Freediving books, train your breath hold with funny games or simply relax with us and the others Freedivers. If you are planning a long training such as Zero to Hero, Master course or some Combo, you will have time to enjoy our social area. To learn Freediving successfully it is important to feel happy, trust your freediving buddies and spent some time having fun to relax the nervous system. Resting and Playing is training!
