What is a disadvantage of SCUBA diving?

The limitation in depth for SCUBA diving is indeed recognized as a disadvantage, although it can vary based on the diver's experience, equipment, and training. Traditional SCUBA diving is restricted primarily due to physiological factors such as nitrogen absorption and the risk of decompression sickness. Each diver's maximum safe depth is influenced by the amount of gas in their tanks and the type of diving they are performing. Additionally, the depth brings along increasing pressure, which may require additional training and specialized equipment for deeper dives, thus making it less accessible for all divers.

In contrast, other forms of diving, such as saturation diving or using mixed gases, allow divers to reach greater depths and spend more time underwater, but they come with their own complexities and safety considerations. The limitations of SCUBA make it less suitable for deep-water exploration compared to more advanced diving systems, thereby highlighting depth as a key disadvantage for specific types of underwater activities.
