What signal could indicate that a dive buddy is in distress?

The identification of a dive buddy in distress is crucial for ensuring safety underwater. Changes in body language or abnormal signals are significant indicators of distress. For example, if a diver is exhibiting erratic or anxious movements, is not following normal dive procedures, or is signaling in unusual ways, it can suggest that they are experiencing problems. These behaviors might include rapid or panicked gestures, a lack of coordination, or other signs that differ from their usual conduct.

In contrast, consistent communication reflects good teamwork and does not inherently indicate distress. Colorful body movements might be playful or expressive rather than a signal of trouble. Similarly, calm breathing patterns are indicative of relaxation and not distress; a diver in trouble may actually have irregular breathing patterns. Therefore, being attuned to body language changes or abnormal signals is essential for detecting distress and initiating timely assistance.
