Performance Requirements:
By the end of this confined water dive, the student will be able to:

1. Don and adjust mask, fins, snorkel, BCD, scuba and weights with the assistance of a buddy, instructor or certified assistant.
2. Inflate/deflate a BCD at the surface using the low-pressure inflator.
3. In shallow water, demonstrate proper compressed air breathing habits; remembering to breathe naturally and not hold the breath.
4. In shallow water, clear a regulator while underwater using both the exhalation and purge-button methods and resume breathing from it.
5. In shallow water, recover a regulator hose from behind the shoulder while underwater. 6. In shallow water, clear a partially flooded mask while underwater.
7. Swim underwater with scuba equipment while maintaining control of both direction and depth, properly equalizing the ears and mask to accommodate depth changes.
8. While underwater, locate and read the submersible pressure gauge and signal whether the air supply is adequate or low based on the gauge’s caution zone.
9. In shallow water, breathe underwater for at least 30 seconds from an alternate air source supplied by another diver.
10. While underwater, recognize and demonstrate standard hand signals.
11. Demonstrate the techniques for a proper ascent.
12. Student time for fun and skill practice.
13. Exit and debrief.
