What is one potential disadvantage of using a regulator with poor performance?

Using a regulator with poor performance can lead to increased gas consumption for a diver. A regulator that does not function efficiently may require the diver to exert more effort to breathe, which can cause them to use air more quickly than a well-functioning regulator would. This not only affects the duration of the dive due to accelerated air depletion but can also lead to a greater likelihood of running low on air, potentially putting the diver in a dangerous situation.

When considering the importance of equipment performance, effective and reliable regulators are crucial, especially in the challenging conditions of cavern diving. The increased demand on a diver's breathing could also contribute to stress and fatigue, further compromising underwater safety. Therefore, the performance of a regulator directly impacts both air consumption and overall diving safety.
