What Are Common Depths For Beginner Scuba Divers (How Deep Is Deep?)
The common depths of beginner scuba divers is somewhere between 18-20 metres (59-66 feet). This limit is set due to the pressure of water at depth and the implications deep water has on scuba divers. Why this is important is due to oxygen toxicity; Boyle’s Law and how the changing pressures at depth impacts gas volumes; decompression sickness or the bends; and nitrogen narcosis. At the next stage of learning to scuba dive, the most common depths are between 18 and 35 metres (59-115 feet).
