--part1_108.ef1824e.29c3dd06_boundary Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Hi There, I certainly hope that either this message is a troll or that you misunderstood what your friend told you about his ascent gas or the depth at which he switched to it. EAN 40 at 160 ft represents a PP(O2) of around 2.4 and no agency or instructor in his right mind would ever permit a student to use this PP(O2). Diving to 200 feet an air is stupid enough because of narcosis, but because of oxygen toxicity, this ascent gas is absolutely ridiculous. Please recheck the numbers your friend is relating to you. Take care and dive safe, Scott Some weeks it's just not worth the effort to gnaw through the restraints and scramble up out of the pit.
