Which of the following actions should be taken when lighting a dive site?

When preparing to light a dive site, observing water clarity is essential for ensuring safety and visibility underwater. Water clarity directly affects how well you can see and maneuver while diving. Poor clarity can obscure potential hazards or change your perception of the environment, leading to potential safety concerns. Understanding water clarity helps divers make informed decisions about whether it is safe to enter the water and what lighting equipment, if any, may be required to ensure visibility once submerged.

Proper assessment of the dive site, including water clarity, sets a foundation for a successful dive, as it informs divers about the conditions they will encounter. This focus on environmental factors is critical for overall safety and enhances the dive experience. Other actions like checking buoyancy or focusing on camera equipment may be important, but without a clear understanding of the water conditions, those preparations could be less effective.
