What technique can enhance visibility during a night dive?

• A. Using reflective gear
• B. Brief, controlled bursts of light
• C. Staying completely still
• D. Moving towards shallow water

Answer: (B)

Using brief, controlled bursts of light is an effective technique to enhance visibility during a night dive. This method allows divers to illuminate their surroundings without overwhelming aquatic life or creating excessive glare that can impair visibility. By using short, directed flashes of light, divers can better observe marine life and identify features in the underwater environment while minimizing the common challenges related to light diffusion in water. Other techniques, such as using reflective gear or staying completely still, do not actively improve visibility in the same way. While reflective gear might add some visibility to the diver themselves, it doesn't enhance the overall lighting conditions in the water. Likewise, remaining totally still might prevent stirring up sediment or disturbing marine life, but it does not aid in clarifying what can be seen in the surrounding environment. Moving towards shallow water might assist in natural light presence but may not be practical or beneficial in all diving locations, particularly if deeper areas are more vibrant or diverse.
