Why is it recommended to wear a rescue tube while teaching swimming?

Wearing a rescue tube while teaching swimming is recommended primarily because it aids in teaching and identifies the instructor. The presence of a rescue tube serves as a visual cue for students, indicating that the person wearing it is an authority figure and a trained professional ready to assist in case of an emergency. This can enhance students' comfort and confidence in the water, knowing that their instructor has the tools necessary for safety.

The tube itself can also be used as a teaching aid, demonstrating techniques for rescues or buoyancy. This dual function—both signaling authority and facilitating instruction—makes it an essential piece of equipment for swimming instructors. It is important for instructors to maintain visibility and presence in the water, and the use of the tube contributes to that aspect of teaching.
