Which technique is effective for maintaining orientation while diving at night?

Using a compass regularly is an effective technique for maintaining orientation while diving at night. In low visibility situations, where natural landmarks are not available and environmental cues can be hard to perceive, a compass provides a reliable reference to ensure divers stay on course. It helps in navigating and understanding direction, allowing divers to maintain awareness of their intended path and return to specific points, such as entry and exit points or landmarks.

In contrast, constantly changing depth can create confusion and disorientation, making it more challenging to maintain a sense of direction. Relying solely on dive lights might not provide sufficient guidance, as lights can only illuminate a limited area and may not help with overall navigation. Swimming in random patterns increases the likelihood of losing one’s bearings, as it lacks structure and intentionality, which are critical when visibility is compromised. Therefore, using a compass regularly stands out as the most effective technique for orientation under these challenging conditions.
