What are the depth limits for recreational and technical diving, and how do they influence your dive planning?
How to Answer
- 1
Understand that recreational diving is generally limited to 40 meters or 130 feet.
- 2
Know that technical diving extends beyond recreational limits, often over 40 meters, but requires special training and equipment.
- 3
Consider factors like nitrogen narcosis and pressure effects at depth when planning.
- 4
Always check the dive site conditions and necessary certifications for deeper dives.
- 5
Include safety measures such as decompression stops and emergency procedures in your plan.
Example Answers
Recreational diving limits are usually set at 40 meters, while technical diving can go much deeper depending on training. For dive planning, I account for these limits by ensuring all divers are qualified for the intended depth and that we have a clear plan for safety and decompression stops.
How do you calculate decompression stops during a dive, and why are they important?
How to Answer
- 1
Understand the concept of dissolved nitrogen in the body during a dive.
- 2
Use dive tables or a dive computer to determine safe ascent profiles.
- 3
Calculate your no-decompression limits and make stops based on depth and time.
- 4
Explain that decompression stops help prevent decompression sickness.
- 5
Be prepared to discuss different types of dives and their specific stop strategies.
Example Answers
I calculate decompression stops by first using a dive computer or dive tables that show my no-decompression limits. Once I know my maximum depth and bottom time, I can figure out how many stops I need to make on the ascent. These stops are vital to allow nitrogen to safely leave my body and avoid decompression sickness.
What should divers know about interacting with marine life to ensure both their safety and the preservation of the environment?
How to Answer
- 1
Always observe marine life from a distance to avoid disturbing their natural behavior.
- 2
Do not touch or feed marine animals as it can harm them and disrupt the ecosystem.
- 3
Be aware of your surroundings and potential hazards in the water to prevent accidents.
- 4
Use environmentally friendly equipment to minimize your impact on marine life.
- 5
Educate yourself about local wildlife and conservation efforts before diving.
Example Answers
Divers should always observe marine life from a distance to avoid disturbing them and refrain from touching or feeding them, as this can harm their natural behavior and the ecosystem.
Explain the difference between air, nitrox, and trimix breathing gases. When is each used?
How to Answer
- 1
Define each gas and its composition succinctly.
- 2
Explain the benefits and limitations of each gas.
- 3
Describe specific scenarios where each gas is preferred.
- 4
Use clear examples to illustrate your points.
- 5
Be prepared to discuss safety considerations and depth limits.
Example Answers
Air is a mixture of about 21% oxygen and 79% nitrogen, used for shallow dives up to 40 meters. Nitrox has a higher oxygen concentration, typically 32% or 36%, reducing nitrogen absorption, beneficial for recreational dives beyond 18 meters. Trimix includes oxygen, helium, and nitrogen, used for deep technical dives over 40 meters to manage narcosis and oxygen toxicity.
What are the physiological effects of pressure changes on the human body during diving, and how do you address them?
How to Answer

- 3
Mention decompression sickness and its prevention through careful ascent.
- 4
Address how to equalize pressure in ears and sinuses during descent.
- 5
Highlight the importance of proper training and adhering to dive tables.
Example Answers
Pressure changes during diving affect the body mainly due to Boyle's Law, which states that gas volume decreases as pressure increases. This can cause issues like barotrauma in air-filled spaces. I equalize pressure in my ears frequently and ascend slowly to avoid decompression sickness.
How do you maintain neutral buoyancy while diving, and why is it important?
How to Answer

- 3
Mention adjustments to weight based on the dive environment.
- 4
Highlight the significance of neutral buoyancy for safety and conservation.
- 5
Emphasize practice and awareness of body position underwater.
Example Answers
I maintain neutral buoyancy by using my BCD to add or release air, which allows me to control my ascent and descent. It's crucial for safety so I don’t disturb the marine environment and can navigate easily.

What is the purpose of dive tables and how do you use them in planning your dives?
How to Answer
- 1
Explain that dive tables help prevent decompression sickness.
- 2
Outline how dive tables indicate safe limits for time and depth.
- 3
Mention the importance of matching dive profiles to tables for safety.
- 4
Discuss planning a dive using tables based on depth and duration involved.
- 5
Emphasize checking tables before and after dives to adjust for multiple dives or surface intervals.
Example Answers
Dive tables are crucial for preventing decompression sickness by showing the limits of time and depth safely. I use them to plan my dives by checking the table for the exact depth and duration to ensure that I'm within safe limits.
