Why is it essential to have a dive light during a night dive?

Having a dive light during a night dive is crucial because it aids in navigation and spotting potential hazards in the underwater environment. At night, visibility is significantly reduced, making familiar landmarks and potential dangers difficult to see. A dive light illuminates the area in front of the diver, allowing for better awareness of the surroundings. This visibility is vital for navigating safely, avoiding obstacles such as rocks or coral, and ensuring the diver can follow their intended route without getting lost.

In addition to navigation, a dive light can help divers spot marine life that may be hiding in crevices or among structures that are otherwise difficult to see in low light. The ability to see and avoid hazards adds a level of safety that is essential for a successful and enjoyable night dive experience.
