PADI Confined & Open Water Skills 5 — Questions and Answers
Question 1: What distinguishes 'open water' from 'confined water' for PADI training purposes?
- Open water is any body of water deeper than 10 meters
- Open water is a natural or man-made body of water with conditions similar to the ocean, requiring divers to manage their own buoyancy (Correct answer)
- Open water must have a visible bottom at all times
- Open water refers only to ocean environments, not lakes or quarries
Correct answer: Open water is a natural or man-made body of water with conditions similar to the ocean, requiring divers to manage their own buoyancy
PADI defines open water as a body of water with open-water conditions where divers cannot stand with heads above water, such as a lake, ocean, or deep quarry.
Question 2: When practicing the five-point ascent in open water, what does each point in the sequence address?
- Signal, inflate, look up, rotate, ascend
- Stop, look up, inflate, release, ascend
- Signal, Look up, Ascend slowly, Stop at 5m, Surface (Correct answer)
- Signal, Inflate BCD, Look up, Release weight belt, Fin to surface
Correct answer: Signal, Look up, Ascend slowly, Stop at 5m, Surface
The PADI five-point ascent covers: signal your buddy, look up and hold your arm up, ascend slowly at 18m/min, stop at 5m for safety stop, then surface.
Question 3: In confined water, students practice breathing from a flooded mask. What is the primary purpose of this skill?
- To improve nasal breathing ability underwater
- To build comfort and confidence so students do not panic if the mask floods during a dive (Correct answer)
- To demonstrate the mask is watertight before open water dives
- To practice equalizing the mask space during descent
Correct answer: To build comfort and confidence so students do not panic if the mask floods during a dive
Flooding the mask in controlled confined water conditions builds psychological comfort so students respond calmly, not with panic, if it happens during a real dive.
Question 4: A student loses their regulator during a dive and cannot locate it. Which technique should they use to recover it?
- Surface immediately without exhaling
- Reach back along the right side of the body to sweep the hose and bring the regulator forward (Correct answer)
- Signal the buddy to donate their primary regulator
- Look over the left shoulder and sweep left arm backward
Correct answer: Reach back along the right side of the body to sweep the hose and bring the regulator forward
Sweeping the right arm behind and along the right side of the body sweeps the regulator hose forward, bringing the mouthpiece back within reach.
Question 5: During the open water checkout dives, which entry method is most appropriate when a student is diving from a low boat platform close to the water's surface?
- Giant stride entry
- Seated rear roll entry
- Forward roll entry
- Controlled seated entry (Correct answer)
Correct answer: Controlled seated entry
A controlled seated entry is safest from a low platform, allowing the diver to slide into the water without falling or losing equipment.
Question 6: What is the primary reason students practice buoyant ascents with no mask during confined water training?
- To demonstrate they can dive without prescription lenses
- To build comfort managing vision impairment underwater and maintaining composure during ascent (Correct answer)
- To test whether the BCD can compensate for lost equipment weight
- To train the eyes to adjust to unfiltered water pressure
Correct answer: To build comfort managing vision impairment underwater and maintaining composure during ascent
Practicing maskless ascents builds emotional resilience and demonstrates that a diver can safely surface even if the mask is lost or flooded beyond clearing.
Question 7: When performing a compass navigation reciprocal heading in open water, a diver on a heading of 60 degrees should return on a heading of:
- 120 degrees
- 180 degrees
- 240 degrees (Correct answer)
- 300 degrees
Correct answer: 240 degrees
A reciprocal heading is found by adding 180 degrees to the original heading: 60 + 180 = 240 degrees.
