We had a good turn out at SDUA on Saturday. There were about 8 people actively participating in the classroom session. We went over many aspects of dive planning, team diving procedures, and then went spent most of the time on gas management. Gas management is a crucial part of diving, from the most basic of courses to the most advanced. They learned how to calculate their SAC rate (surface air consumption) and then how to convert that into RMV (respiratory per minute volume) at depth. Then went through quite a few different scenarios to give them a working knowledge of how this would relate to their current diving. Also covered was how quickly their gas supply can be depleted during an emergency, especially during sharing air emergencies. It seemed as though everyone came away with a sense of enlightenment. All in all a good time.
During the practical ( in water) prortion, we performed three one hour dives over the two days. During which we covered sdrills, mask removal and clearing, frog kicking, reverse frog, helecopter turns, failure scenarios, controlled timed ascents (midwater simulating deco), and lift bag deployment. Now they have plenty to practice to prepare for their deco class.
