What is the purpose of maintaining moderate line tension at all times?

Maintaining moderate line tension throughout the dive is crucial primarily for preventing line tangling. When there is too much slack in the guideline, it can create loops or knots, making navigation difficult and potentially leading to disorientation or loss of the line altogether. Keeping sufficient tension helps keep the line straight and manageable, allowing divers to follow it securely.

While the visibility of the guideline, emergency exits, and deployment may be influenced by line management, they are secondary to the primary goal of avoiding complications from tangles. Thus, consistently applying moderate tension is key to ensuring a safe and efficient dive operation within cavern environments.
