What should instructors emphasize regarding diving safety?

Emphasizing the importance of checking for depth and obstacles is crucial in diving safety because it directly relates to preventing injuries that can occur from improper diving conditions. Divers must assess the water's depth to ensure there is enough space to dive safely without hitting the bottom or any submerged objects. Additionally, checking for obstacles such as rocks, swimmers, or other hazards prevents accidents that can lead to serious injuries. Educating swimmers about these considerations fosters a safer environment and promotes responsible diving practices, significantly minimizing risks associated with diving.

Focusing on stylish dives, eliminating diving altogether, or emphasizing competitions does not directly address the fundamental safety concerns that should be prioritized during swimming lessons. Safety should always take precedence over technique, aesthetics, or competitive aspects.
