What equipment is required to run a scuba dive shop? I am not referring to the personal scuba gear (mask, fins, BC, regulators etc.) I’m referring to equipment for the maintenance & repair shop.

you will also need a helium leak detector to help you check to ensure none of your supplies are leaking. that would be dangerous to your customers. just think what would happen if a diver bought an oxygen tank that has slowly been leaking for weeks….. disaster right. btw, it is possible because that almost happened to me
