Apologies if it's mentioned in one of the few pages I didn't read. Air fills get mentioned a lot in this thread. One thing that occurs to me is that we don't seem to have invented / created / developed an automatic air-fill machine. I suspect that the majority of divers just dive on air. Do we need a human to do that air-fill? Why not just have a machine which you can insert your cylinder, attach the whip yourself, close the door, swipe your "cert" card, and insert the relevant $ into a coin slot?
I know that this isn't really promoting LDS, but is it a natural progression? We pump our own gas or LPG into our cars (and gas/LPG have the same potential to cause injury or death if mishandled), so why not our own air?
I am sure it is technically possible but I do not think you can make enough money just selling air to cover the cost of the machine. Much like a suggestion made earlier for a mobile compressor that could be taken to local dive sites, it will work but there would not be enough profit to sustain it. Future advances in compressor technology could change that down the road though. Something like that could work in a chain sports store that sold other equipment but did not have people well versed in diving on staff.
