Imagine seeing the aquatic world with your own eyes, from turtles to sharks. Diving in Koh Tao gives you the opportunity to live this amazing experience. ¿Do you want?

Diving in Koh Tao is much more than a simple hobby! This is because it is one of the best places in the world where you can find the most biodiversity, thanks to its beautiful crystalline waters.

Koh Tao, also called “Turtle Island” in Thai, is considered the Mecca of diving. For that, it is one of the most visited islands in Thailand, with diving lovers from all over the world.

If you are thinking of trying scuba diving in Thailand, Koh Tao is a mandatory visit.

Where to dive?

If you come to this island, there are a lot of diving centers, but in our diving center, Nitro Dive, you will enjoy diving while having fun in a good atmosphere and with very professional instructors.

Diving in Koh Tao, with our diving center Nitro, is an amazing experience of the crystalline waters, but more for all the animals you can see. Diving in Koh Tao can be possible at all types of levels, from try scuba to advanced divers, or more. 

Diving can be just as dangerous as driving or jogging. We are underwater where we need specific equipment to be able to breathe, which is why it is important to do it under the supervision of professionals following safety regulations. Various studies conducted in the US, Canada, or Japan show that the statistical probability of death while diving is 2-3 per 100,000 dives.

Our policy at Nitro Dive is to teach you the entire diving procedure so that you have all the necessary knowledge before entering the water. Our courses are small (less than 4 people), the experience is more personalized and the error rate is minimal.

The practice of diving, today, is limited to people over 8 years of age and has no maximum age limit, as long as it does not have physical and/or mental complications. Depending on the country, it is necessary to undergo a medical check-up to certify that you are fit and that diving is safe. In other countries, such as Thailand, you only have to fill out a form. We review it in detail, and if there are 1 or more existing medical conditions, it will be necessary to obtain a medical certificate.

SSI (Scuba Schools International) and PADI (Professional Association of Diving Instructors) are organizations featured to diving certificates. 

SSI emphasizes flexibility and adaptation of teaching to each student, offering free digital materials and fostering local diving communities. On the other hand, PADI is characterized for having a standard approach, with educative material worldwide, but it has an additional price. Both organizations are recognized around the world, but depends on you what teaching style you prefer.

Nitro Dive has a very clear policy to ensure the enjoyment of all its divers. Less experienced divers will enjoy the knowledge of a diving professional, while more advanced divers can enjoy their diving excursions with other divers of the same level. In our diving center, Nitro Dive, divers who need to do a refresh course are:

  • Certified divers with less than 20 dives, with the date of their last dive being between 6 months and a year.
  • Certified divers with less than 50 dives and more than a year without diving.
  • Certified divers who feel the need for additional attention and want to start with basic exercises such as equipment assembly, mask and regulator emptying, air exchange, etc.

The safety and enjoyment of all our divers is the most important thing to us and we make no exceptions to avoid accidents and bad experiences.

When breathing compressed air under the sea we absorb nitrogen bubbles, before traveling we have to wait for them to leave our body. Having done 1 dive you have to wait 18 hours, if you do 2 or more you must wait 24 hours.

Amazing diving school but even better people. We did our baptism and nothing could be better. Our instructor, Albert, is great! He showed us how to dive safely to avoid any problems, so don't worry about this. We arranged the Open Water course but, unfortunately, due to some health issues, we couldn't do it at the end. They were worried about us all the time and they gave us back the money without even asking for it. Thank you for everything!

La academia es increíble. Les recomiendo pedir que Joji sea su instructora. No solamente te trabaja las técnicas del buceo sino que tiene mucha paciencia para enseñarte. La verdad una de las mejores experiencias en Koh Tao.

Hemos disfrutado mucho de sacarnos el Open Water con ellos, hay un ambiente fenomenal. Nos han aconsejado en todo momento sobre la isla. No nos olvidamos de Bego, no nos podría haber tocado mejor instructora… persona top. Gracias por todo!

Hice mi curso de Open Water con ellos y la experiencia estuvo increíble. Íba por un bautizo y termine completando el curso gracias a la buena onda y predisposición del equipo. Izan, el instructor, un genio, explica todo con mucha claridad y te hace sentir muy seguro abajo del agua. Recomiendo hacer buceo en esta isla y hacerlo con esta empresa, todo el ambiente es súper buena onda y todos dispuestos a ayudar y enseñar. ¡Gracias! ❣️

Tuvimos la suerte de que en nuestro primer Diving después de sacarnos el Padi nuestra instructora fuera Bea. Nos hizo un pequeño refresh de todo y nos explicó a los sitios que íbamos a ir e incluso los tipos de fauna y flora marina que nos encontraríamos. Bea es una instructora fantástica. Siempre muy pendiente fuera y bajo el agua. Además de muy paciente!! Lo pasamos increíble y aprendimos mucho; Gracias a Nitro por elegir una instructora tan genial! Bea la mejor!💥
