Nitrox Dive Activities

This is what you will do during a nitrox dive.
- Assemble your equipment, and check the assembly with your buddy.
- Listen to and participate in the dive planning and briefings.
- Review hand signals.
- Make sure all dive planning is done based on the nitrox mix being used.
- Gear up and complete the pre-dive buddy safety checks.
- Enter the water in the manner discussed in the briefing.
- 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.
- Monitor your PDC.
- Complete a controlled descent without a reference line to a maximum depth of 18 meters/60 feet.
- Without touching the bottom, make sure you achieve neutral buoyancy at an agreed depth.
- Demonstrate swimming and trim. Under the direct supervision of your instructor, you will swim in a horizontal position while finning correctly.
- Practice the skills based on what your instructor has determined to be the objective of your dive.
- Ascend with an emergency NDL stop. To simulate this, your instructor will signal that you have a PDC warning that requires a decompression stop.
- Achieve positive buoyancy on the surface.
- Exit the water in the manner discussed in the pre-dive briefing.
- Complete post-dive equipment care.
- Listen to and participate in the debriefing.
- Use a PDC to see new NDL, or calculate the end-pressure group with tables.
- Calculate SAC and RMV.
