1. What is the primary purpose of the AIDA 2 Freediver level?
A. To prepare divers for unrestricted deep-water competition
B. To develop foundational freediving skills, knowledge, and safe diving practices
C. To certify divers as professional instructors
D. To qualify divers for technical scuba diving
AIDA 2 develops fundamental freediving knowledge and skills while emphasizing safe
practices, buddy procedures, breathing awareness, equalization, and appropriate depth
progression.
2. During a freediving session, which factor should take priority over achieving a planned
depth?
A. Completing the dive exactly as scheduled
B. Matching the deepest dive of the group
C. Maintaining safe technique and recognizing personal limits
D. Increasing depth whenever the first dive feels easy
Safe freediving requires the diver to prioritize control, technique, and physiological awareness
rather than treating a target depth as mandatory.
3. What is the main role of a properly trained freediving buddy?
A. To compete with the diver
B. To monitor and assist the diver according to established safety procedures
C. To determine how deep the diver must go
D. To pull the diver downward during difficult equalization
A competent buddy provides active safety supervision and is prepared to respond
appropriately to problems during the dive.
4. Which breathing pattern is generally appropriate before a normal freedive?
A. Relaxed, normal breathing
B. Rapid maximal breathing
C. Continuous forceful hyperventilation
D. Breath-holding for several minutes before entry
Relaxed normal breathing helps the diver prepare without unnecessarily disturbing carbon-
dioxide levels or increasing physiological stress.
,5. Why is deliberate hyperventilation before a breath-hold dangerous?
A. It makes the lungs physically smaller
B. It increases carbon dioxide too rapidly
C. It can lower carbon dioxide and delay the urge to breathe
D. It guarantees a longer and safer breath-hold
Hyperventilation can reduce carbon dioxide substantially, potentially delaying the warning
sensation of rising CO₂ while oxygen continues to fall.
6. A freediver feels unusually anxious immediately before entering the water. What is the
best decision?
A. Dive deeper to overcome the anxiety
B. Increase hyperventilation
C. Ignore the feeling because anxiety is always harmless
D. Pause, regain calm control, and reassess whether to dive
Mental readiness is part of safe freediving. A diver should not feel pressured to enter the
water when not adequately calm or prepared.
7. What is the primary purpose of relaxation in freediving?
A. To eliminate the need for a buddy
B. To reduce unnecessary energy expenditure and promote efficient diving
C. To increase competition speed
D. To prevent all equalization problems
Relaxation reduces unnecessary muscular and mental effort, helping conserve oxygen and
improve overall efficiency.
8. Which statement best describes a static apnea exercise?
A. Breath-holding while remaining stationary
B. Diving vertically to maximum depth
C. Swimming horizontally without fins
D. Surface swimming while breathing normally
Static apnea involves holding the breath while remaining stationary, commonly on the
surface or in a controlled training environment.
9. During dynamic apnea, the diver primarily:
A. Remains motionless at the surface
B. Descends and ascends vertically
C. Covers a horizontal distance underwater on a breath-hold
D. Uses compressed gas equipment
Dynamic apnea involves horizontal underwater movement while breath-holding and is
commonly performed in a controlled pool environment.
,10. Which equipment item is specifically designed to improve propulsion efficiency in
freediving?
A. Weight belt only
B. Freediving fins
C. Surface marker only
D. Dive computer charger
Freediving fins provide efficient propulsion and are designed to help the diver move through
the water with reduced effort.
11. Why are long freediving fins useful?
A. They eliminate the need for equalization
B. They can provide efficient propulsion with relatively low-frequency fin movements
C. They prevent all leg fatigue
D. They allow unlimited depth
Long fins can generate effective propulsion efficiently, helping the diver conserve energy
when used with proper technique.
12. A freediver's mask begins leaking repeatedly. What should the diver do?
A. Ignore the leak and descend farther
B. Continue until the planned depth is reached
C. Stop or adjust the dive and correct the problem safely
D. Remove the mask underwater during descent
Equipment problems should be addressed rather than allowed to compromise comfort,
visibility, breathing control, or overall safety.
13. Why is a low-volume freediving mask commonly preferred?
A. It requires less air to equalize the mask space
B. It automatically equalizes the ears
C. It eliminates the need for a nose clip
D. It prevents hypoxia
A low-volume mask contains less air space, making mask equalization easier and reducing the
amount of air required to equalize it at depth.
14. What is the purpose of a nose clip in freediving?
A. To increase lung volume
B. To prevent water from entering the lungs
C. To keep the nostrils closed while allowing certain equalization techniques
D. To replace all equalization methods
A nose clip closes the nostrils while leaving the mouth available, which can be useful when
performing hands-free or specialized equalization techniques.
, 15. Which equipment choice is generally most appropriate for a beginner freediver?
A. Equipment that fits properly and supports safe, efficient movement
B. The heaviest available weight belt
C. Extremely rigid fins regardless of comfort
D. Equipment selected solely because it is expensive
Proper fit, comfort, suitability, and safe function are more important than price or extreme
performance characteristics.
16. What is the primary purpose of a wetsuit in freediving?
A. To provide compressed air
B. To improve hearing underwater
C. To maintain thermal protection and comfort
D. To eliminate buoyancy changes
A wetsuit provides thermal insulation and can help the diver remain comfortable during
extended exposure to water.
17. Why should a freediver consider wetsuit thickness carefully?
A. Thickness can affect thermal protection, flexibility, and buoyancy
B. Thickness determines oxygen concentration in the water
C. Thickness eliminates equalization requirements
D. Thickness guarantees neutral buoyancy at all depths
Wetsuit thickness affects warmth, flexibility, and buoyancy characteristics, all of which can
influence freediving performance and safety.
18. A diver is properly weighted at the surface but becomes increasingly negatively buoyant
during descent. Why?
A. Water pressure compresses the wetsuit and air spaces
B. Saltwater removes body weight
C. Fins become heavier because of gravity
D. The diver automatically loses body mass
Answer: A
As pressure increases, gas-containing spaces and the wetsuit compress, reducing buoyancy
during descent.
19. Why can buoyancy change significantly during a freedive?
A. Water temperature changes every second
B. Pressure changes compress gas-containing spaces
C. Body weight disappears underwater
D. Fins stop generating thrust
Answer: B
