what part of pre dive planing is so hard to understand?x amount of time at x depth then move up to x depth for x time and so on..worked great for 4 years in the military since 1981 and still works great 27 years down the road but i guess it cost's to much to buy a credit card size slate and pencil and would take up to much time to waste 15 minutes with the others in the group on a good solid pre dive plan session ...so please explain to me in detail how us old dudes came back alive from dives before the pdc ?was it an act of god? or dumb luck? please enlighten me ?
