What should a diver do if they lose sight of their buddy during a night dive?

In a night dive, visibility can be significantly reduced, making it easy to lose sight of a buddy. The correct action is to signal using your light and remain calm. Utilizing the dive light not only enhances visibility but also serves as an important communication tool to alert your buddy of your location. Staying calm is crucial because it helps you think clearly and take appropriate actions to reunite with your buddy safely.

Seeking to signal is vital in helping both divers navigate back to each other because the light beam can be seen from a distance, even in low visibility conditions. Remaining still and signaling allows your buddy to locate you more easily, enhancing the chances of reuniting without disorientation or unnecessary risks during a dive that may already have limited visibility.

Other options may introduce unnecessary risk or complications in this situation. For instance, proceeding independently can lead to disorientation and complicate the situation further by creating distance and confusion. Attempting to surface immediately can also be dangerous, as doing so without proper assessment can lead to ascending too quickly or surfacing in an unsafe area. Lastly, while staying at the last known position might seem prudent, it could be ineffective if the buddy is not actively searching near that point or if they have also lost visibility. Thus,
