We had our first diving experience with diving instructors Fabio, Ana, Shai and Chris today and it was amazing! They were very professional, easy going and supportive during the whole process. Very nice experience from the reception at front desk up till the last minute! S&J
⭐⭐⭐⭐⭐ Did my Advanced Open Water with Good Time Adventures and had an incredible experience. My instructor Fabio was great. He really made sure I understood everything with the exact mix of theory and practice, helped me improve my skills and feel more confident in the water. The night dive was something I was nervous about, but he made me feel safe and it’s an experience I’ll never forget. The boat crew was lovely too, instructors Ana and Shai and the other students made the whole thing even more fun. Highly recommend! 🤿❤️
Doing the open water diver at good time was an amazing experience. Our teacher Lydia really took her time to explain everything calmly and understandably, it was perfect to get into the world of diving. She also focused on our weaknesses, so we could improve a lot over the 3 day course. I can 100% recommend doing your open water diving course with goodtimes and lydia!!
Oh my goodness, this place is absolutely incredible! 🤩 Everything was perfect, from start to finish! 💯 What an amazing experience doing the Open Diver Course! Lydia our instructor was the absolute best and made the experience even more wonderful 😄 I would surely come back here for fun dives and doing further certifications.
Had a great scuba diving experience here. Chris was an excellent instructor - patient, professional, and reassuring throughout the dive. He made me feel comfortable and confident as a beginner. Highly recommend!
Did an intro scuba course with Chris and it was amazing. Super patient, clear, and made the whole thing feel fun and safe. Highly recommend.
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.
