  10. Hold inflator

Descent review

  • You should equalize your air spaces every few meters while descending, before you feel discomfort.
  • If you feel discomfort in your ear while descending, ascend until discomfort is gone, attempt to equalize once again and continue a slow descent.
  • Free descent: Take care to avoid disorientation, watch your descent rate, maintain buddy contact.
  • The most important rule in scuba diving is: Breathe continuously and never hold your breath.
  • Stay in front of the vessel.
  • On board with min. 20…40 bar.
  • Use the stern line if behind the vessel.

  5. Look upwards

Post-dive / Exit

  • Inflate BCD at the surface and signal OK
  • If you feel discomfort during ascent due to air expansion in any body air space during ascent slow or stop your ascent, descent a few meters and allow the trapped air to work its way out.
  • Board one diver at a time, while others stay well clear.
  • Prepare to immediately lend assistance.
  • Ascertain dive profiles.
  • Remind to clear the exit area.
  • Visually confirm that everyone is aboard and accounted for (roll-calls).
