Scaph Club

Practical scuba gear references and unit tools for traveling divers

A small reference site for divers

Dive gear does not agree on units. European tanks are stamped in bar, American gauges read psi, rental shops quote wetsuit thickness in millimeters, and depth signs switch between meters and feet depending on which side of the ocean you got certified.

Scaph Club is a small, fast reference site for exactly those moments. The tank pressure converter below translates between bar, psi, atmospheres, and metric pressure units instantly, in your browser, with nothing to install and nothing tracked.

Around the tool you will find short, practical guides to the equipment side of recreational diving: what the numbers stamped on a cylinder actually mean, how to think about wetsuit thickness when you are packing for a trip, and when it makes sense to stop renting and buy your own gear.

This site covers equipment and units only. It does not teach diving, and nothing here replaces proper training with a certified instructor or the guidance of the operator you dive with.
