Which of the following is a disadvantage of scuba?

Limited physical protection is a recognized disadvantage of scuba diving. While scuba gear provides a certain level of safety and protection, divers are still relatively exposed to the underwater environment. Unlike surface-based activities where divers could have more robust protective equipment, scuba divers rely primarily on wetsuits or drysuits that offer limited protection from sharp objects, stings, or potentially hazardous underwater terrain. This limited physical protection can lead to injuries, such as cuts or abrasions, that would need to be managed immediately since divers are often at a distance from immediate medical assistance.

In contrast, the other options present benefits rather than disadvantages. Unlimited endurance is misleading in the context of scuba diving since physical limitations and air supply ultimately determine how long one can dive. Enhanced communication is generally a positive aspect with the advent of underwater communication devices. Increased buoyancy control is an advantage that allows divers to maintain desired depth and position more effectively while underwater. Understanding these nuances helps divers better prepare for the challenges they may face when diving.
