PADI or SSI — Which Should You Choose?
Both PADI and SSI are globally recognized, permanently valid, and accepted at dive sites, liveaboards, and rental shops worldwide. PADI holds a slight edge in name recognition — particularly in North America and the UK — but the practical difference is negligible for recreational divers. SSI courses in Koh Tao typically cost THB 500–1,000 less and include digital study materials free, whereas PADI eLearning is an additional ~$50 USD. For most divers, the school and instructor matter far more than the certification agency.
Is Koh Tao Good for Beginners?
Yes — Koh Tao is one of the best places in the world for beginner divers. The water temperature stays at 28–30°C year-round, meaning no wetsuit is required (a 3mm suit is optional). Visibility averages 10–25m, with the clearest conditions from February to April. With 70+ competing dive schools on a tiny 21 km² island, standards are high and prices are low. Koh Tao issues approximately 65,000 PADI certifications per year — more per square kilometer than almost anywhere else on the planet.
