PADI, SSI or RAID? Divemaster, instructor or videographer? This is everything you need to decide — without a dive school doing the selling.
The agency you train with can affect your employer network, course cost and how you're perceived abroad. Here's what actually differs.
The largest recreational diving agency in the world. PADI certifications are recognized by more employers globally than any other agency — especially outside Southeast Asia.
Scuba Schools International is the second-largest agency and is particularly strong in Southeast Asia and Europe. Digital-first, often cheaper, and widely used on Koh Tao.
Originally tech-diving focused, RAID now covers recreational. Technology-forward with a strong environmental and educational orientation. Limited presence on Koh Tao.
