I had great respect for diving. I went to the school based on a friend's recommendation. In this diving school I felt comfortable and safe thanks to the well-trained diving instructors. My respect was replaced in the water by the fascination of the underwater world. Putting on the material for the first time after dry runs and theory lessons and jumping into the big water is something I wish everyone could experience. I can heartily recommend it. I was allowed to complete the open water course with you. A very friendly family team which you can feel as an "external" student. Many thanks for the safe and motivating training to the whole Team. Greetings Joel

I did my open water with them and I have to say that it was a really great experience, thank you to my instructor Hector. Héctor had a lot of patience, he managed perfectly all the situations and questions that we had, he made it really calm and easy, very professional. Also he creates a perfect environment with the buddies, so if you have the chance, fully recommended!!

We actually "only" wanted to do the open water 18m, but then we got a taste for it super quickly and added the advanced open water. We couldn't have wished for a better instructor, Federico has all the skills to be the perfect teacher. His lessons are exciting and informative, entertaining and, above all, we felt safe at all times. An absolute recommendation. Thanks to Fede and Nitro Team!

I did the 3-day open water course at Nitro and felt welcome from the first moment. The theoretical education prepared us well for the diving in the open sea, and our teacher Teo did a fantastic job in teaching us all necessary skills in an easygoing, relaxed manner. The vibe on the boat was always great, and the diving was certainly the highlight of my stay at Koh Tao. Thanks to all who went out of their way to make this an unforgettable experience. 100% recommended for both English and Spanish speakers!

Professional, well organized and a trust-based respectful atmosphere- for the marine life and the (soon to be) divers! Loved to make my open water license here, couldn’t have chosen a better place. Thanks Iñigo for being such a great instructor <3 Team Princess learned from the best!

Me and my friends did our open water, advanced and rescue courses at Nitro and really enjoyed it. All our instructors were very professional and managed to really convey the subject matter without sacrificing the fun of scuba diving in the process. The office staff were very clear anytime you had questions and they could even help me with a prescription mask. Special thanks to Cynthia, Jaume and Mero!

This has been the nicest experience for many years🙏 Our teacher Joji Fernandez was supporting and very good educated🥽 So much fun 3 days. The opportunity to do this together with Joji and my partner was absolutely fantastic. Joji is the best❤️❤️❤️ Nitro divecenter is super🤗 We will be back🥰

At first, me and my girlfriend booked 2 basic dives with these guys, but we had such a great time that we ended up doing the Open Water certification after. We were really amazed by the profesionallity and kindness of the people here, especially our instructor Nahuel, who was very patient and made us feel very safe, even though this was our first time diving ever! Really recommend these guys - they have a great vibe!

We did the Open water course at Nitro- highly recommend this place for anyone who wants to learn diving or is an experienced diver already. Everyone there was so nice, the whole vibe was just very chill and it feels like you're immediately part of the Nitro family. Also special thanks to Nahui who was the best teacher we could have ever wished for! We'll be back! 🤙🏼

We did the open water and advanced courses. It was such a great experience! Everything was very professional and the atmosphere was also amazing. We want to say thanks to our guide Theo. He was all we could ask. He made those days just wonderful. Very recommended!!!

I’ve heard about Nitro before arrived to Koh Tao because of 2 people talking very good about it. So I went to Koh Tao looking for the Open Water and I loved it! Jorge, my instructor is amazing, a lot of patience teaching you, his mood is always happy, so I really enjoyed diving with him. Also, they are looking after you every time, checking the safety on the equipment and also yourself. Very good experience, if you want to learn the basics to dive this is the place! And also Koh Tao has a beautiful sea animals to see, if you lucky you could see the whale shark which is amazing. Definitely I wish to come back to Nitro!

Just finished my advanced today with Jo as our instructor! She’s just one of the coolest persons I met since I arrived in the island. Such a nice vibe she has! Really happy I did it in this school. Massive thanks to Nitro Dive Center and Jo, you’re the best! 🤙 You guys are awesome!

Amazing experience!! I can’t find words to recommend it more. Lovely staff and really patient with us. We were a group of 5 and they gave us plenty of options to be able to do our open water course even though some of us were kind of scared and never dove before. I will be back for the advance course. Thanks Erik and Andres who make our experience really great and enjoyable!!! Sissy is the best too. See you soon!

I completed my open water diving certificate at Nitro dive center, and it was beyond amazing! My instructor Srikar was very friendly, knowledgeable, patient and made learning a breeze. The dives, specially in the last day, were unforgettable. Highly recommend this place for an incredible diving experience!

wonderful experience. thanks to joij for these 3 days of diving with her professionalism and passion. I had fun and I recommend you definitely come and try open water at nitro.
