What is a common practice for dive site selection for night diving?

Selecting familiar sites with established markers is a common practice for night diving because it enhances safety and navigation. Familiarity with the dive site allows divers to understand the terrain, potential hazards, and where to find safety markers that can assist in navigation during limited visibility conditions, which are inherent to night diving. The presence of established markers provides reference points that guide divers back to the entry point and ensure they stay oriented throughout the dive.

In contrast, sites with strong current flow may prove challenging for both navigation and safety at night, as currents can change unpredictably and create additional risks. Unfamiliar sites introduce uncertainty and increase the likelihood of disorientation during a night dive. Choosing sites with maximum depth might also pose risks, as deeper waters can have more challenging conditions, and divers may not have the necessary experience or safety measures in place for deeper dives at night. Therefore, selecting familiar sites with established markers is the most prudent approach for night diving.
