If you are looking for a one day dive, we definitely highly recommend them. They have great equipment and absolutely amazing instructors. Ana and Mike were the best! But the whole goodtime team was perfect, smiling, friendly and helpful! Mike took pictures of our underwater experience and we have memories to last a lifetime. Once again a huge thank you! 🤙🏻❤️
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! ☺️
Had the most incredible experience diving for the first time with goodtime adventures. Lydia was an amazing instructor- she explained everything really clearly and made sure we felt comfortable and confident throughout. Logan & Andrea were also great on the boat!
Lydia did such a great job with our group. We were all beginners and she made the experience so fun, safe, and informative! I’d recommend her and the company to anyone curious about diving.
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. 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.
