I think you have misunderstood what the default cylinder setting does. If you have AL80 as your default cylinder then all cylinders that are added to a particular dive will have the properties of an AL80; 11,1l, 207bar. > When I get stuck in some dead, usually I directly edit the xml file > but two friends of mine who are Subsurface new adopter were caught > immediately into the "current gas is in use..." dead end without being > able to solve it. > Copy-paste was a Linus brilliant idea to avoid inserting each dive all > the tanks.

Unless of course that you add cylinders, assign switches and then paste the information from an older dive. > Why it's compulsory to have a cylinder into the cylinder table? > // Jocke
