In your third dive session, you will further extend your capabilities, including dealing with some failure scenarios. Before your third dive:
- Your instructor may wish to demonstrate a skill and have you practice it before you get into the water like you did with your first two dives.
- Your instructor will discuss planning for dives that you will complete in your open water section of the course.
- You and your instructor will use the air diving tables to calculate the allowable dive time and compare this to the time allowed on the PDC.
