What is the maximum recommended depth for recreational scuba diving?

The maximum recommended depth for recreational scuba diving is typically considered to be 40 meters, or 130 feet. This depth is established to ensure the safety of divers, minimizing the risks associated with increased pressure, nitrogen absorption, and potential deco issues that occur at greater depths.

At 40 meters, divers still have a reasonable amount of time before experiencing significant nitrogen narcosis and enhanced decompression obligations. It is also where many training organizations set their limits for recreational diving courses. Diving deeper than this often requires additional training, equipment, and techniques to manage the increased risks effectively.

Understanding this recommended depth helps divers recognize their limits and the additional precautions needed if they consider deeper dives, reinforcing safety as a priority in recreational diving.
