Scuba Review
Already certified but haven’t dived for over 6 months? No problem, after a short refresher programme we can get you back safely in the water ready to dive at some of Koh Tao’s most spectacular dive sites. Firstly one of our expert SSI Instructors will run you through a knowledge review to recap on safe diving practices, dive planning and problem management. Then you’ll go over equipment fitting and set up, before jumping into a shallow water session to revisit those essential dive skills you learnt in your initial training. By the end of your scuba review you’ll be feeling comfortable and confident underwater, and ready to join us on a fun dive at one of Koh Tao's amazing dive spots!
Sail Rock Dive Trip
We run Sail Rock trips the same way we approach the rest of diving at Goodtime: smaller groups, experienced staff, and enough flexibility to adapt to conditions instead of forcing the same dive plan every day. Offshore sites demand a bit more awareness than the shallow reefs around Koh Tao. Currents shift. Visibility changes. Marine life moves. Having guides who know the site well makes a difference, especially for divers visiting Sail Rock for the first time. Our groups stay intentionally small so the dives feel calm and manageable underwater. Briefings are detailed without turning into lectures, and the goal is always to help divers feel comfortable enough to actually enjoy the site rather than simply tick it off a list. Sail Rock has a reputation that stretches well beyond Koh Tao. For a lot of divers, this is the site they talk about afterwards. The dive where the water suddenly filled with barracuda. The day a whale shark appeared halfway through the safety stop. Availability: ONLY runs every Tuesday, Thursday, and Friday.
3S Diving Trip
Some dive days are just dive days. The 3S is something else. Departing Mae Haad at 9am, you’ll spend the day exploring three of the Gulf of Thailand’s most iconic dive sites, combining big pelagics, vibrant reefs, dramatic underwater landscapes, and crystal-clear blue water. Southwest Pinnacle kicks things off with towering granite pinnacles covered in spectacular anemone fields, home to giant groupers, schools of trevally and barracuda, with the chance of a whale shark passing through. Shark Island offers a completely different experience, with boulder formations, colourful coral walls, moray eels, triggerfish, and abundant reef life. Sail Rock finishes the day at the Gulf’s most celebrated dive site, famous for its towering pinnacle, chimney swim-through, huge schools of fish, and the region’s best chance of encountering a whale shark. Three unforgettable dives. One epic day. Certified divers only.

SSI Divemaster – Starter Package
Goodtime takes the standard SSI Divemaster curriculum and expands it through areas of real professional diving that prepare a new candidate for the reality of the industry — not just the exam. That means more time in the water, more exposure to actual dive operations, and a closer relationship with the professionals running them. Goodtime recommends at least 8 weeks for the Starter package. While the SSI program can be completed faster, the difference extra time makes to a new professional is significant — you need space to absorb the information and practice the skills properly. The Industry Ready and Career Builder packages run to 10 and 12 weeks respectively. SSI professional active status fees are ฿16,900 and are paid directly to SSI. These are not included in any of Goodtime’s tuition packages. They cover your SSI membership and first year of active professional status.
