What is the maximum working limit depth for a combat diver?

The maximum working limit depth for a combat diver is set at 130 feet. This depth is established to optimize both the safety and efficiency of divers operating under combat conditions. At 130 feet, divers can effectively carry out their missions while still managing physiological risks such as nitrogen narcosis, which can impair cognitive functions and decision-making abilities.

Operating within this depth allows for the use of standard breathing gas mixtures while minimizing the risks associated with deeper dives, such as oxygen toxicity and the need for complex decompression procedures. It also aligns with training and operational protocols developed by military organizations that emphasize diving safety and operational effectiveness. Consequently, this depth represents a practical balance between operational capability and safety, providing combat divers with the necessary limits to perform their tasks efficiently while maintaining a safe margin against decompression sickness and other diving-related hazards.
