Course Outline

The maximum depth for open water dive 3 is 18 meters/60 feet. For juniors, the maximum depth is 15 meters/50 feet.

This is what you will do during dive 3.

  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 perform the pre-dive safety check with your buddy.
  4. Enter the water in the manner discussed in the briefing.
  5. Check your buoyancy at the surface.
  6. Perform an S-Drill, and monitor your instruments.
  7. Complete a controlled descent without a reference line to the maximum depth for your course.
  8. Monitor your instruments.
  9. Establish neutral buoyancy at your instructor’s assigned depth.
  10. Practice failure scenarios. Your instructor may give you a signal for one of these and expect you take the appropriate action:
    1. Instruments not working
    2. Feeling uncomfortable/unwell
    3. Missing buddy

  12. Practice swimming and trim. Under the direct supervision of your diving instructor, you will swim in a horizontal position while finning correctly.
  13. Complete your ascent with a safety stop for 3–5 minutes at 5 meters/15 feet while maintaining buddy contact.
  14. Practice 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.
