About Scaph Club

Scaph Club is a reference site for recreational scuba divers in the United States. It exists to do one narrow job well: gather the planning habits and safety references that certified divers are taught and then gradually forget, and present them in plain language with links to the primary sources — NOAA's diving program, the CDC's traveler-health guidance, Divers Alert Network, and the Undersea & Hyperbaric Medical Society.

The site is written for certified divers and people working toward certification. It assumes you have (or will get) real training from a recognized agency; nothing here replaces that. The Pre-Dive Readiness Checklist is a self-assessment of preparation, not a fitness-to-dive screening, and none of the guide pages constitute medical advice. If you have a medical question about diving, that conversation belongs with a physician trained in dive medicine — the Undersea & Hyperbaric Medical Society is the professional body for that field.

Every page on this site is reviewed reference material: summaries of what established organizations publish, with citations so you can verify claims yourself. Where a number matters — like how long to wait before flying after diving — we cite the source that publishes it rather than asking you to trust us.
