We had a fantastic first day of diving with Mira today. Safety and well-being are clearly a top priority. Service is paramount here. High-quality diving equipment. The proximity to the harbor means you can quickly get to the boat and have the freedom to choose between a morning or afternoon dive. We'd love to do it again! ☺️

I would definitely recommend taking Open Water Diving with Goodtime. They are super professional and at the same time made the experience easy and really fun. I had the great pleasure of having Lisa as my instructor and I can't put a word to any of the teaching. Thank you so much for 4 amazing first dives! I would also like to give a shout out to Bart, Charlie, Brian and Ana for being so nice and helpful throughout the process.

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.

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 Open Water or PADI 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 using an 80/20 approach. Instructors can adapt 20% of the course to match each student’s learning pace.

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.

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.
