The signs of a dive buddy in distress are crucial for ensuring safety underwater. A buddy exhibiting rapid ascents, flailing arms, or panic-driven gestures clearly indicates a loss of control and potential danger. Such behaviors often stem from situations where a diver may be experiencing a lack of buoyancy control, an unexpected aquatic encounter, or simply feeling overwhelmed by the environment. Recognizing these signs allows for prompt intervention by the dive buddy, which can be vital to providing assistance, regaining control, or making necessary adjustments to the dive plan.

In contrast, calm movements and controlled breathing suggest that a diver is managing their situation effectively, which doesn't necessarily indicate distress. A lack of communication and quietness might occur in various scenarios, not all of which involve distress – it could simply reflect that a diver is focused or enjoying the dive. Swimming away from the dive group may signal a lack of awareness or focus rather than direct distress. Overall, recognizing the specific signs of distress can significantly enhance the safety of both the diver in question and their buddy.
