What is the maximum working limit for SCUBA diving?

The maximum working limit for SCUBA diving, particularly for recreational purposes, is generally considered to be 130 feet (40 meters) based on the guidelines established by agencies such as PADI and NAUI. However, for some advanced diving practices and specialized training, divers can work deeper, reaching up to 190 feet (approximately 58 meters) with proper training and equipment.

The specific limit of 190 feet reflects the depth at which divers can still effectively carry out operations while managing the risks associated with increased ambient pressure, potential narcosis, and the challenges posed by deeper water environments. Beyond this depth, divers are advised to use different breathing mixtures and advanced techniques. It is essential to consider the risks involved with increased depth, including the need for enhanced training, careful planning, and strict adherence to safety protocols to mitigate the associated risks of deeper dives.
