What does the acronym SCUBA stand for?

The acronym SCUBA stands for Self-Contained Underwater Breathing Apparatus. This definition accurately captures the essence of the equipment used by divers, as it allows an individual to dive independently while providing the necessary air supply for breathing underwater. The "self-contained" aspect signifies that the system is portable and includes everything needed for a diver to breathe autonomously without relying on external air sources, which is essential for safety and mobility during dives. Understanding this term is crucial for divers because it highlights the autonomy and self-sufficiency that SCUBA gear offers in an underwater environment.
