Had the BEST time at good time. The instructors here are amazing and hold the highest standards. Special shoutout to Ana my open water instructor and Carmen my advanced open water instructor, I feel way more confident in my diving and skills. Thanks Charlie for being so accommodating, definitely recommend choosing this for a more one on one dive experience!!!
On June 29th, I did a refresh dive with Lydia as instructor. It had been quite a while since my last dive, and I thoroughly refreshed the basics, both theory and practice. Lydia is amazing! She is a skilled communicator, has a pleasant voice, knows what she is talking about, and takes her time with you. The two dives were relaxed, and she knows how to avoid the crowds underwater. I felt safe and am entering the water again with full confidence. Thank you! And Bente... thank you for your tips! Regards, Joris
Goodtime Diving was awesome! We came to Koh Tao to get our Open Water certifications and talked with a bunch of different dive shops, and Good Time was definitely the best one. We enjoyed the course so much that we decided to also get our Advanced Open Water and Nitrox specialty with Goodtime Diving. Shout out to our instructor Shai, who was so passionate, patient, and engaging throughout every course. He explained everything clearly, made sure everyone understood both the theory and practical skills, and was always happy to go over things again whenever we needed. His enthusiasm made every dive fun and helped us feel confident and comfortable in the water. We couldn't have asked for a better instructor and would highly recommend Good Time Diving to anyone looking to learn to dive on Koh Tao!
This place is not only a wonderful place to chill with a beer to watch the sunset and have some good food but also obviously for diving and adventure! Shoutout to Ana for excellent scuba instruction- she is patient, cheerful, thorough , and a wonderful soul 🇧🇷. Shoutout to Shai for being careful, attentive, and I learned a lot in my Advanced Open Water course. I like that it was a small group of 3. (Goodtimes can do it with 1 person!! ) . Shoutout to Logan for being a talented photographer and a relatable world traveler- chill vibes. Shoutout to Andrew for being an experienced climber with some cool routes to share. Shoutout to Charly for running a competent and excellent business here on Koh Tao. Shoutout to the bar & kitchen team for being so kind and hardworking.
Had such a fun time doing my open water here!! Shai was the best instructor, very thorough and explained everything well. The dives were beautiful, and I couldn’t have imagined getting certified anywhere else! Also shoutout to Charly for being so kind and helpful throughout the whole process :)
Had a great couple dives with Ben, super friendly staff, good equipment, and a beach club on site for a cheeky after-dive pint with the team. Precisely what Koh Tao is about! Cheers
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.

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.
