About the founder

RAID Instructor. 2,000+ dives.
One obsession: better briefings.

George Blizzard is a RAID dive instructor based on Koh Tao, Thailand. He has logged 2,000+ dives across an intensive career and built A Scuba Guide as a working tool — the visual briefing system he wished he'd had on his first day teaching students.

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 format has barely changed in 30 years: a whiteboard sketch, a flip chart of fish, a 15-minute talk that varies by whichever instructor is on shift that day. New instructors copy the briefing they happen to learn first. Students forget half of it before they kit up.

George got tired of briefing Chumphon Pinnacle from a whiteboard for the hundredth time and started building 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.
