What is one factor influencing the limitations of SCUBA diving?

The influence of currents is a significant factor impacting the limitations of SCUBA diving. Strong underwater currents can create challenging conditions for divers, affecting their ability to navigate and complete their dives safely. Currents can alter the buoyancy and position of divers, making it difficult to maintain stability while exploring or performing tasks underwater. In addition, they can lead to increased fatigue, as divers may need to exert more effort to swim against or maneuver through these currents. Therefore, understanding and assessing current conditions is crucial for dive planning and ensuring the safety of the dive team.

On the other hand, increased underwater visibility typically enhances the diving experience and safety. Availability of speech communication, while beneficial for team coordination, does not influence the physical limitations of diving in the same way. Extended air supply might allow for longer dives but does not address the challenges posed by environmental factors like currents. Thus, the influence of currents stands out as a primary factor in determining the limitations of a SCUBA diving experience.
