RAID Instructor. 2,000+ dives.
One obsession: better briefings.
George Blizzard is a RAID dive instructor from the UK who has spent the last few years instructing in Koh Tao, Thailand and Dhangethi, Maldives. He has logged 2,000+ dives across an intensive career and shaped A Scuba Guide as a working tool. The visual briefing system he wished he'd had on his first day teaching students.
George leads the Koh Tao Pack with local dive pros: the people who brief these reefs every day, correct details when they drift, and care that Thai staff get the same reference surface as visiting instructors.

The dive count, honest version.
George has logged more than 2,000 dives across a career compressed into a small number of intensely-active years. Most of that time has been spent on the boats around Koh Tao: briefing students, leading certification dives, running fun dives, and paying attention to the same reefs every day until the patterns revealed themselves.
Why this tool exists.
Every Koh Tao dive school briefs students before the dive. The depth, currents and hazards stay consistent — every instructor on the island can run those in their sleep. The marine life half is where briefings fall apart. Which species get named, how their behaviour gets explained, what gets skipped — all of it depends on whichever instructor is on shift and which fish they happened to learn first. Students surface having seen creatures they can't put a name to.
George took a keen interest in learning more about the fish he saw on dives, spending his downtime researching the ecology of the species he saw. Learning the behavioural patterns, habitats and fun facts of the species not only developed the dive briefs but also the underwater experience he shared with his students. After collating the data he started shaping A Scuba Guide. Every dive site, every species, every cross-link, in your pocket on the boat.
Cert-agnostic by design.
George teaches under RAID, but he is intentional that the tool serves the whole island. Koh Tao runs roughly 50 dive shops across RAID, PADI and SSI. The physical reality of the dive sites is the same for all of them. The briefing tool should be too.
Conservation belongs in the guide.
The Global Reef partnership gives conservation work a practical route into the product: clearer species context, better local corrections, and a guide that helps trainees notice the reef rather than just pass a course.
