Course Outline

The maximum depth for open water dive 2 is 12 meters/40 feet.

This is what you will do during dive 2.

  1. Assemble your equipment, and check the assembly with your buddy.
  2. Listen to and participate in the dive planning and briefings.
  3. Gear up and complete the pre-dive buddy safety checks.
  4. Enter the water in the manner discussed in the briefing.
  5. Complete a buoyancy check at the surface.
  6. Perform an S-Drill, and monitor your instruments.
  7. Complete a controlled descent with a reference line to a maximum depth of 12 meters/40 feet.
  8. Monitor your instruments.
  9. If you were unable to complete the S-Drill and bubble check after entering the water, do a bubble check immediately upon arriving at a stable depth but no deeper than 6 meters/20 feet.
  10. When you are near the agreed depth, adjust and stabilize your neutral buoyancy. Do not touch the bottom.
  11. Monitor your instruments to check:
    1. Air/gas supply
    2. Depth
    3. Allowable dive time
  12. Review hand signals.
  13. Clear a fully flooded mask.
  14. Remove, replace, and clear the mask.
  15. Practice regulator recovery using the sweep method. Recover the primary second stage with the arm sweep method.
  16. Practice swimming and trim. Establish neutral buoyancy; and then under the direct supervision of your diving instructor, you will swim in a horizontal position while finning correctly.
  17. Practice ascent gas sharing. While underwater, your instructor will give you the appropriate signal whereupon you will react with the correct response for a low-on-gas situation.
    1. You signal your buddy you are out of breathing gas.
    2. Your buddy will supply their primary regulator to you.
    3. Your buddy will locate and breathe from his or her AAS.
    4. Both buddy team members will hold on to each other, monitor the instruments, and give the OK signal once settled.
    5. You ascend using a reference line. Make a safety stop at 5 meters/15 feet for 3–5 minutes. Remember:
      1. The low-on-gas diver must keep a careful watch on the gas supply.
      2. On the surface, establish positive buoyancy as a priority.
      3. If the water is rough, leave your regulator in and relax until the boat picks you up.
  18. Exit the water in the manner discussed in the pre-dive briefing.
  19. Complete post-dive equipment care.
  20. 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.
