What is a cookie in diving terminology?

In diving terminology, a cookie refers to a specialty non-directional marker used primarily for navigation and indicating specific points of interest within an underwater environment. These markers help divers maintain awareness of their surroundings and provide reference points for navigating through a cavern or cave system. Unlike directional markers, which might point toward a specific exit or route, a cookie does not provide directional guidance but serves to mark important locations, such as junctions or obstacles. This use of cookies is crucial for maintaining awareness of a diver's position and contributing to overall dive safety.

Using cookies effectively ensures that divers can retrace their path and navigate complex terrains, particularly in environments where visibility might be restricted. By employing these markers, divers enhance their situational awareness, facilitating a safer exploration of underwater habitats.
