What is generally defined as deeper diving?

Dives to depths greater than 18 meters are generally recognized as deeper dives within the context of scuba diving. This depth is significant because it marks a transition where divers can experience increased physiological effects and risks associated with higher pressures, such as nitrogen narcosis and oxygen toxicity. Dive training organizations, including NAUI, consider 18 meters as a threshold for more advanced techniques and knowledge to mitigate these risks.

Understanding the specific challenges that arise in deeper diving scenarios is crucial for diver safety and the development of appropriate skills and knowledge. By categorizing dives beyond this depth as deeper, training and preparation can be focused on addressing the complexities that accompany such dives, including planning, managing gas mixes, and executing emergency procedures effectively.
