Which navigation technique is used when diving in wrecks?

The feature reference technique is particularly effective in wreck diving because it relies on the physical structure of the wreck to orient oneself during the dive. Divers can use prominent features of the wreck, such as large openings, identified areas, or unique elements of the ship, to navigate rather than solely depending on a compass or other tools. This is especially useful in complex environments where visibility may be limited or when the surroundings might confuse navigational aids.

Using feature reference allows divers to create a mental map of the wreck, thereby facilitating safe navigation through its various compartments and enhancing the overall dive experience. This method aligns well with the nature of wrecks, where divers often need to navigate through intricate spaces and avoid disorientation.

While using a compass is a common navigational practice, it can be less effective in enclosed or cluttered environments like wrecks where lines of sight may be obstructed. Conducting safety stops is crucial for ascent but does not pertain to navigation techniques during the dive, and signal communication, while important for diver safety and coordination, does not serve the purpose of physical navigation within a wreck structure.
