If a personal marker from another team is found, how should it be treated?

When a personal marker from another team is found, it should not be relied upon for navigation because it may not be an accurate representation of the current environment or conditions. Personal markers are typically used by divers to orient themselves and track their paths, but without knowledge of who placed the marker, how it was placed, and under what circumstances, it becomes unreliable. Different teams may have varied marking systems or may have placed markers for different purposes, which could lead to confusion or misdirection during navigation.

Using an unfamiliar marker can pose significant risks, especially in cavern diving, where conditions can change rapidly and visibility can be limited. This is why divers are trained to establish their own navigation tools and markers in order to maintain situational awareness and ensure safety. Relying on markers placed by unknown teams can lead to potential errors in navigation and increases the likelihood of getting lost or disoriented within the cavern system. Therefore, it's crucial to treat personal markers from other teams with caution and not depend on them for navigation.
