What is a common challenge divers face during limited visibility night dives?

Maintaining orientation is a significant challenge during limited visibility night dives due to the lack of light and environmental cues that divers typically rely on. In dark or murky waters, familiar landmarks may be obscured or completely invisible, making it easy for divers to lose their sense of direction. Divers often need to rely on instruments such as compasses or pre-planned dive routes to navigate effectively. Additionally, the disorienting effect of poor visibility can lead to increased stress and anxiety, complicating the ability to stay oriented underwater.

While the other challenges like identifying underwater flora, finding buddies, and sorting gear are relevant, they do not pose the same degree of fundamental navigation difficulties that poor visibility does. In low-light conditions, familiar landmarks become indistinct, and divers may struggle to keep track of their surroundings, making orientation challenges paramount during night dives.
