We had a really great time with Loris, Mike and Ollie who took great care of our group during the basic diver course. I was super nervous after the basics and wasn’t sure I wanted to continue, and they really helped me with confidence to move forward. I’m so grateful they did!

This dive shop was amazing. My wife and I had a tremendous experience diving for three days. So many people to shout out: Lydia- was our DM the first day and was lots of fun and very easy to work with. Tim was great the next two days for our diving. Very layed back and let us enjoy our fun dives. Ana— lead my wife on a night dive and was very knowledgeable. Oliver- he was on the boat with us and was very helpful. Lucas and Charlie in the shop (and a very nice lady who’s name I don’t remember) were all very helpful and professional. Overall can’t say enough good things and I will certainly come back and dive with them!

Frequently Asked Questions

Frequently asked questions about Scuba Diving in Koh Tao

Scuba Diving in Koh Tao has been very popular for years, we have some of Thailand’s best dive sites and great diving conditions all year round. Our most popular course is the SSI Open Water Diver course which takes 2.5 days to complete and allows to to dive all over the world once you are certified. This course is ideal for beginners who want to get Scuba certified on Koh Tao.

If you are short on time the SSI Basic Diver is for you! This is a half-day experience where you can dip your toes in and explore the underwater world.

Any of the dive organisations in the world can give you the Open Water license, and with it you can dive in every dive centre in the world for the rest of your life – an SSI diver can of course dive in a PADI centre or the other way round, for example.

However, with SSI you do get benefits:

Online Learning
While most organisations offer online learning, not all of them offer it free of charge and can end up racking up quite the bill. SSI offers your learning materials for free as part of your course registration and is easy to navigate using the MySSI app. The app is regularly updated and also offers additional free courses like the ´Try Diving´ and the ‘Blue Oceans‘ for you to enhance your scuba diving knowledge.

Recognition Ratings
SSI do things a little differently to other diving agencies, they continue to recognise your advancement in diving whether you are enrolled in a course or not. When you reach certain milestones you will be awarded recognition status. This is why we encourage specialities over the SSI Advanced Adventurer or Advanced Open Water courses. With SSI once you complete 4 speciality courses and 24 dives you will automatically be rewarded with Advanced Open Water recognition status. Taking this route allows you to explore your passions underwater without being restricted to one exploration dive per specialty! Don’t forget we offer discounts on bundles too!

Flexibility
SSI allows its professionals to teach with an 80/20 approach meaning that the instructor can adapt 20% of the course to fit the pace of learning, ensuring a student focused training programme worked around the needs of the students – after all everyone learns at different paces.

The minimum age to learn to scuba dive and become certified is ten years old. If the diver is between 10-14 they will be awarded with a Junior SSI Open Water Certification that will automatically upgrade to Open Water Diver once they turn 15.

However, the SSI Explorers program provides options for children aged six and up to experience diving and snorkeling in very shallow water.

Diving in Koh Tao is popular for its year-round diving conditions, boasting clear waters, vibrant marine life, and stunning dive sites available 365 days a year. Whether you’re a beginner starting with an SSI Open Water Diver course or an experienced diver, diving in Koh Tao offers it all—excellent training sites, famous dive spots, shipwrecks, and pinnacles like Sail Rock.

Yes, a basic level of in-water ability is required to scuba dive. For certain courses, you’ll need to complete a water fitness evaluation before heading into the open water. This includes either a 200-meter unaided swim or a 300-meter swim using a mask, snorkel, and fins. These requirements ensure your safety and confidence during your underwater adventures.
