What is a "tethered rescue"?

A "tethered rescue" refers to a rescue technique in which the rescuer maintains a physical connection to the distressed diver, usually through a line or tether. This method is essential when dealing with situations where the environment is challenging, such as strong currents or limited visibility, as it allows the rescuer to guide and control the movement of the distressed diver while ensuring that they remain within reach. The tether acts as a safety measure, helping to prevent the rescuer and the distressed individual from becoming separated, which is particularly crucial in emergency scenarios.

In contrast, the other options describe different concepts that do not accurately define a tethered rescue. Swimming alone does not provide the safety and support that tethered techniques do. Rescuing multiple divers simultaneously typically involves different strategies and equipment, which is not the focus of a tethered rescue. Finally, jump techniques might be relevant in certain rescue scenarios but are unrelated to the concept of being tethered during a rescue.
