What is one advantage of surface supplied diving systems over SCUBA systems?

One significant advantage of surface supplied diving systems over SCUBA systems is the increased bottom time provided by the continuous air supply. In surface supplied systems, divers are connected to a hose that supplies air from the surface, allowing them to breathe without the limitations of tank capacity that SCUBA divers face. This arrangement enables divers to remain underwater for extended periods, as they are not constrained by the finite air supply contained in tanks.

In a SCUBA setup, as the diver consumes air, they must monitor their air supply closely and ascend before running out of air, which restricts their time at depth. In contrast, the continuous flow of air from the surface in a surface supplied system eliminates this concern, allowing divers to focus on their tasks underwater rather than managing their air supply carefully. This capability is especially beneficial for operations requiring prolonged underwater work or exploration, making surface supplied diving systems particularly suitable for commercial diving, research, and complex underwater tasks.
