What can I do to help you understand? SB is a great place to learn, it works better if you listen more then you talk especially if you are talking about something you say you do not understand. In a discussion about safety you are the only one talking about money. That would suggest that buying a computer is more important for the money you make then the safety of the diver buying it. Does that clear it up for you?
Never said I did not understand how tables and computors do work. What I do not understand is why you do prefer tables to computors. As I said earlier, in a lot of places in the world, you would NOT BE ALLOWED to dive without a personnal dive computor.
