How do lines assist divers during wreck dives?

Lines are useful tools for divers during wreck dives primarily because they facilitate navigation. When divers explore an underwater wreck, the environment can be challenging due to reduced visibility, complex structures, and potential disorientation. Lines assist divers by providing a tactile reference that helps maintain their orientation and aids in safely navigating through the wreck. Divers can follow the line to return to the entry point or to guide their movements along specific pathways within the wreck, allowing for a more organized and safer dive experience.

In wreck diving, navigating visually may be limited, so a line can serve as a reliable guide, ensuring divers can find their way back especially in unfamiliar or intricate wrecks. This is crucial in enhancing safety during the dive, allowing divers to focus on the exploration without the added stress of losing their way within the wreck structure.
