What navigational aid can enhance safety during wreck dives?

Using a baseline as a navigational aid during wreck dives enhances safety primarily by providing a reliable reference point for divers. A baseline, typically a length of rope or line that is secured to the wreck or another stable object, allows divers to orient themselves and maintain a consistent path while exploring the wreck site. This is particularly important in potentially disorienting environments like wrecks, where visibility may be limited and structural complexities can lead to confusion.

With the baseline in place, divers can effectively plan their route and return safely without the risk of getting lost. It serves as a direct navigational tool that helps divers understand their position in relation to the entry point and the surrounding environment, making it easier to manage time and air supply during the dive.

Diving computers and referencing dive tables pertain more to managing dive profiles and decompression limits rather than navigation. While following dive guides can aid in navigation, the use of a baseline provides a more direct and practical solution for maintaining orientation specifically in wreck diving scenarios.
