Scaph Club is a small reference site for recreational scuba divers. The name comes from scaphandre, the old French word for a diving suit, and the site sticks to the unglamorous side of the sport that actually keeps people out of trouble: planning dives properly, knowing the standard safety references, and understanding what to do when something goes wrong.
The centerpiece is the Pre-Dive Readiness Checklist, a quick self-assessment you can run through the night before a dive trip or in the parking lot before you gear up. It scores how complete your preparation is — currency, dive plan, gas plan, conditions check, gear status, and emergency information — and tells you plainly where the gaps are. It is not a substitute for your training agency's procedures; it is a structured way to make sure you actually followed them.
Around the checklist are a handful of guide pages that answer specific questions divers actually ask: how long to wait before flying after diving, how no-decompression tables work and why they still matter in the computer era, how to recognize decompression illness and respond, and how to dive responsibly in U.S. national marine sanctuaries. Every page cites primary references — NOAA, the CDC, Divers Alert Network, and the Undersea & Hyperbaric Medical Society — so you can go straight to the authoritative source rather than taking a website's word for it.
