A Nitrox diver chooses 32% O2 to dive at 100 ft (30m). His buddy, a rebreather diver, chooses a set point of 1.3 for the same dive. How will the two divers' plans differ, and will there be a difference in their time limits? Will their recommended surface interval and 2nd dive time (to the same depth) differ?
Dead man walking??
Do a course.
You cant/shouldnt learn to dive rebreathers on the internet.
