What is the maximum depth limit for surface-supplied systems other than Divator DP?

Surface-supplied diving systems are commonly used in commercial diving operations, and each system has specific operational depth limits based on safety, equipment capabilities, and physiological considerations. For surface-supplied systems, a general maximum depth limit is recognized, often set at 60 feet of seawater (fsw) for many standard operations. This limit is designed to ensure the safety of divers by reducing the risk of complications that can arise at greater depths, such as increased narcosis or other physiological stresses.

Understanding that 60 fsw is well within safer operational limits for divers using these systems supports the rationale behind this maximum depth. At depths beyond this point, divers may require additional training, specialized equipment, and safety protocols to address the increased risks associated with deeper diving. This is why the answer regarding the maximum allowable depth limit accurately reflects standard practices in surface-supplied diving up to that specified depth.
