The story of a lost dive fin highlights the importance of situational awareness in scuba diving. A student diver impulsively chased after his fallen fin, neglecting safety protocols. His instructor had to balance ensuring the group’s safety while rescuing the diver. Both diver and instructor became fixated on the immediate problem instead of considering the larger risks involved. Reflecting on such incidents and understanding decision-making processes can improve situational awareness and enhance safety for future dives.
