What action should you take if you hear a continuous sound from your dive computer during a dive?

A continuous sound from your dive computer typically indicates an alarm that signals a critical situation, such as exceeding a preset limit for depth, no-decompression time, or ascending too rapidly. Each dive computer is programmed with specific alarms to alert divers to conditions that require immediate attention to ensure safety.

By referring to the dive computer instructions, you are effectively addressing the situation at hand. Understanding what the alarm signifies allows you to take appropriate and necessary actions, which might include adjusting your depth or ensuring that you are within safe ascent rates. This proactive approach is essential for maintaining safety during your dive.

In comparison, ignoring the sound or turning off the dive computer could lead to failure to address a potentially dangerous dive condition. Similarly, an immediate ascent without understanding the reason for the alarm could result in other complications such as decompression sickness, since the alarm might be indicating that you are ascending too quickly or have reached a no-decompression limit. Ensuring you are aware of and responsive to the alarm’s meaning is crucial for maintaining safe diving practices.
