When may a diving team attempt complex navigational techniques?

A diving team may attempt complex navigational techniques when each diver understands the cave and the techniques involved. This understanding is crucial because successful navigation in underwater cave systems requires a high level of situational awareness, familiarity with the cave environment, and proficiency in navigating using both natural and artificial references. Without this foundational knowledge, divers risk disorientation and potential hazards that can arise from inadequate navigation skills.

Practicing in a controlled environment, such as a pool, can help divers become familiar with some basic skills, but it does not replace the need for a thorough understanding of the specific cave system they will be diving in. Likewise, while reading guidelines is important, it does not ensure that divers will be prepared to navigate complex caves effectively without practical application and comprehension of the unique challenges posed by those environments.

Attempting complex navigation techniques only after the first dive would not allow for sufficient preparation or understanding of the cave environment, which could lead to unsafe conditions for divers. Therefore, the emphasis on comprehending the cave and the navigation techniques is essential for ensuring a safe and successful diving experience.
