What is the best way to maintain orientation during a night dive?

• A. Use of natural landmarks or a dive compass
• B. Rely on a dive buddy's guidance
• C. Follow the current
• D. Swim in a straight line

Answer: (A)

Maintaining orientation during a night dive is crucial for ensuring safety and navigating effectively in an environment where visibility is limited. Using natural landmarks or a dive compass is the most effective way to achieve this. Natural landmarks can provide tangible reference points that divers can identify even in low light conditions, helping them track their location relative to the entry point and exit path. Similarly, utilizing a dive compass allows divers to maintain their intended direction by giving them a reliable tool to follow a heading. This is especially important because, at night or in limited visibility, divers may easily become disoriented without visual cues. Relying solely on a dive buddy can introduce subjective elements into navigation, such as differing levels of experience or unexpected changes in the environment that may affect the buddy's sense of direction. Following the current may not be advisable, as currents can change and lead divers away from their intended path. Swimming in a straight line might seem straightforward but can be challenging without proper reference points, making it easy to get lost or miss critical navigation markers. Therefore, combining natural landmarks with a compass provides the most reliable and effective means of maintaining orientation during a night dive.
