Nitrox Dive Activities

This is what you will do during a nitrox dive.

1. Assemble your equipment, and check the assembly with your buddy.
2. Listen to and participate in the dive planning and briefings.
3. Review hand signals.
4. Make sure all dive planning is done based on the nitrox mix being used.
5. Gear up and complete the pre-dive buddy safety checks.
6. Enter the water in the manner discussed in the briefing.
7. Perform an S-Drill. If conditions prohibit your bubble check after your entry, check immediately upon your arrival at a stable depth but no deeper than 6 meters/20 feet.
8. Monitor your PDC.
9. Complete a controlled descent without a reference line to a maximum depth of 18 meters/60 feet.
10. Without touching the bottom, make sure you achieve neutral buoyancy at an agreed depth.
11. Demonstrate swimming and trim. Under the direct supervision of your instructor, you will swim in a horizontal position while finning correctly.
12. Practice the skills based on what your instructor has determined to be the objective of your dive.
13. Ascend with an emergency NDL stop. To simulate this, your instructor will signal that you have a PDC warning that requires a decompression stop.
14. Achieve positive buoyancy on the surface.
15. Exit the water in the manner discussed in the pre-dive briefing.
16. Complete post-dive equipment care.
17. Listen to and participate in the debriefing.
    1. Use a PDC to see new NDL, or calculate the end-pressure group with tables.
    2. Calculate SAC and RMV.
18. Log the dive online.
