How should divers react to poor visibility underwater?

When underwater visibility is poor, divers should prioritize safety and navigation. Staying close to each other allows for better communication and support, which is especially crucial in conditions where sightlines are limited. By maintaining close proximity, divers can assist each other if one becomes disoriented or requires help. Navigating with caution is essential because poor visibility can lead to disorientation and potential dangers, such as becoming lost or encountering obstacles.

The approach of separating to find better visibility can lead to increased risk, as divers might lose sight of each other completely, making it harder to reunite or assist one another. Swimming upward quickly could cause divers to ascend too rapidly, risking decompression sickness or other hazards. The idea of using bright colors to signal each other is less effective in low visibility situations where colors may not be discernible due to murky water.
