What is the standard maximum depth for recreational scuba diving?

The standard maximum depth for recreational scuba diving is 40 meters, or 130 feet. This depth limit is recognized by various diving organizations and reflects a general consensus on safe practices among recreational divers. At this depth, divers can engage in typical recreational diving activities while still within the limits of safety regarding decompression and the effects of pressure.

Diving beyond this depth increases the risks associated with nitrogen narcosis and decompression sickness, as well as the physiological responses to high pressure. Although experienced divers may exceed this limit under specific circumstances, 40 meters is widely accepted as the upper limit for recreational diving without the need for special training or considerations. This standard promotes safer diving practices and greater enjoyment of underwater experiences.
