PADI Advanced Open Water Diver Course Outline

The PADI Advanced Open Water course is the next step for most divers who are looking to broaden their diving skills and experience. The course includes a variety of adventures such as deep dives, boat diver, underwater naturalist and other adventure dives that require more skill level than an introductory dive would demand.

Participants will also learn how to plan your own Adventure Dive itinerary while learning about risk management in recreational scuba diving and expedition planning techniques.

In addition, 15 elective adventure dives can be chosen from either shore or boat options which include Deep Dives, Underwater Naturalistship (only available on courses at certain locations) Boat Diver and many others! All participants must have completed the PADI Open Water Diving Certificate or qualifying certification from another organization with a comparable skill level.

Knowledge Quick Review

Answer 1. Look for no longer than 1 minute, then head to the surface.

Answer 2. You are experiencing a squeeze. You need to equalize your air spaces.

Answer 3. Start your dive against the current, and return helped by it.

Answer 4. Never hold your breath.

Answer 5. Aquatic animals attack only when they feel threatened.

Answer 6. You are properly weighted for scuba diving when, at the surface and with an empty BCD, you float at the level of your eyes holding a deep breath. As soon as you exhale, you will slowly start to sink.

Answer 7. If your buddy is close, simply signal that you are out of air and switch to your buddy’s alternate air source.

Answer 8. A diver experiencing nitrogen narcosis will act foolishly at depth. They will not respond to instructions and act without any consideration for their or other divers’ safety.

Answer 9. Reduce your DCS chances by avoiding diving too deep, too close to your computer’s limits, going over no-deco time and by always doing your safety stop. Also, avoid diving when dehydrated, sick, out of shape and in strenuous conditions.

Answer 10. After 2 dives in one single day, your minimum recommended no flight time is 18 hours.

Deep Adventure Dives

Answer 11. Any dive deeper than 18 meters – 60 feet, but still within the 40 meters – 120 feet – limit for recreational diving, is a deep dive.

Answer 12. You should consider having a reference line for your descent and ascent, an additional tank at 3 meters for your safety stop, appropriate thermic protection, additional weights, dive lights, and of course emergency oxygen given the highest chances of DCS.

Answer 13. Always descend and ascend feet down, maintain your position to avoid disorientation, and keep the 5 meters level for the 3 minutes safety stop at the height of your heart and lungs.

Gas Narcosis

Answer 14. A diver experiencing nitrogen narcosis will show inappropriate and foolish behaviour, slow thinking and reaction response, semi-consciousness, inability to follow instructions or to understand signals, and will most likely not remember any of this after the dive.

Answer 15. Keep your buddy safe, if they do not respond to your instructions simply take them to shallower depth where the effects of narcosis will vanish, and stick to that maximum depth for the rest of the dive.

Answer 16. Narcosis is a temporary situation that happens at a specific depth in that specific moment in time. It is nothing life-threatening provided that we react appropriately and timely to it.

Decompression Sickness

Answer 17. DCS or Decompression Sickness, is a condition that results from rapid ascents or excessive build-up of nitrogen in our blood stream. Bubbles will form in our tissues causing pain, numbness, cramps, and even paralysis and death.

Answer 18. Symptoms of DCS include pain, numbness or tingling, unusual fatigue,
skin itch, dizziness and vertigo. Its signs include the diver favouring one arm or leg, paralysis, unconsciousness, staggering, collapse, coughing and blotchy skin.

Answer 19. If we suspect DCS, it is extremely important to have a prompt reaction: administer 100% oxygen to the diver and contact the nearest emergency medical facility. Do not attempt in-water recompression.
