For RAID · PADI · SSI schools

Brief every student with the same accuracy your best instructors have.

A Scuba Guide is a free dive briefing tool for RAID, PADI and SSI dive schools on Koh Tao. It gives every instructor on your roster the same canonical site notes and species list — so a new hire briefs Chumphon Pinnacle the same way your most senior instructor does. Built by George, a working RAID instructor with 2,000+ dives.

The whiteboard problem.

Most Koh Tao dive schools brief students the same way they did in 1995: a whiteboard sketch of the dive site, a flip chart of fish, and a 15-minute talk that varies by whichever instructor is on shift. New instructors copy the briefing they happened to learn first. Students forget half of it before they kit up.

A Scuba Guide replaces that with a visual, tappable briefing every instructor reads from — every Koh Tao dive site, every species, cross-linked, accessible on any phone in the boat or the classroom.

What you get in the pilot.

  • Unlimited instructors. No per-seat pricing.
  • Unlimited student access. They open it on their own phones.
  • Every Koh Tao dive site, every species, cross-linked.
  • Offline-capable on the day boat once loaded.
  • Direct line to George for site notes corrections and feature requests.

Cert-agnostic by design.

A Scuba Guide does not lead with PADI, does not lead with RAID, does not lead with SSI. The briefing content is the same physical reality — depth, current, marine life, hazards — regardless of which agency's standards your shop teaches under. George is a RAID instructor; the tool is everyone's.

Frequently asked questions.

Is A Scuba Guide really free for dive schools?
Yes. During the early-access pilot every Koh Tao dive school can use it for free with no per-instructor or per-student cost. We take post-pilot pricing decisions when we have real usage data; pilots will get grandfathered terms.
Will it work for my RAID, PADI or SSI school?
Yes. Every dive site and species page is written cert-agnostic — there are no PADI-only fields, no RAID-only language. Instructors brief from the same shared site notes regardless of which standard they teach.
Do my instructors need to install anything?
No. They open the URL on any phone, tablet or laptop, and add it to the home screen if they want a one-tap launcher. There are no accounts, no logins and no app store gatekeeping.
What about offline on the boat?
The tool is a Progressive Web App. Once it has been opened on a device, the dive site notes and species data are cached locally and continue to work without signal — exactly the conditions your day boats run in.
