The first dive is to 18 m/60 ft for 24 minutes. How long would I have to stay on the surface to do these 2 dives safely?32 minutesI dive to 17 metres/56 feet for 47 minutes. After a 30-minute surface interval I do a second dive to 17 metres/56 feet. Losing track of time, I notice my bottom time is now 25 minutes. According to the General Rules, what should I do?Ascend (go up) right away to 5 metres/15 feet and stay there for at least 8 minutes before going to the surface, and not dive for six hoursA group of Advanced Open Water Divers plans to make two dives. The first dive is on a reef in 22 metres/80 feet of water for 20 minutes. The group then remains on the surface for 1 hour. The second dive is on a wreck in 18 metres/60 feet of water, with a planned bottom time of 30 minutes. What will be the ending pressure group after the second dive?RMy buddy and I are planning to dive at a site where the water and air temperature are near freezing. We plan to dive to 18 metres/60 for 30 minutes. What dive profile would we use when planning our dive?22 metres/70 feet for 30 minutesI am an Advanced Open Water Diver. I plan to do three dives. The first dive is a 25-metre/80-foot dive for 22 minutes followed by a 52-minute surface interval. The second dive is to 20 metres/70 feet for 27 minutes followed by a surface interval of 62 minutes. My third dive is to 18 metres/60 feet. What would be my maximum allowable bottom time for this third dive?34 minutes
