I started diving less than a year ago, but I immediately fell in love with it and went all in. I’ve started my divemaster course and intend to do the IDC after 6 months as a divemaster. I’m confident and comfortable with my skills, except air consumption. I’m 6’2” 240 lbs so I suck a lot of air. 20-30 ft I average an hour but at 50 ft it’s more like 35-40 mins (with 3 min SS and coming up with 5-6 bar). Will I encounter problems as a DM? Ive never been the diver that required the group to turn around because of low air, but worried I’ll lead a dive and have to turn before a paying customer needs to. Is there anything I can do to decrease my air consumption?
