Diving Tables

It is important that all divers plan their dives prior to entering the water. Consideration must be given to the altitude at which you are diving as this can seriously affect you oxygen & nitrogen consumptions. Make sure that you have obtained a valid diving qualifaction and are afay with the Buhlmann tables prior to using them. Planning your dives on the wrong altitude tables could be fatal.
