What does a downward pointing triangle indicate on a dive computer?

• A. The diver is safe to surface
• B. The diver has exceeded the decompression ceiling and should descend immediately
• C. The diver is within limits for safety
• D. The diver is approaching the end of the air supply

Answer: (B)

A downward pointing triangle symbolizes that the diver has exceeded the decompression ceiling and now needs to descend immediately to avoid potential decompression sickness. This visual alert on a dive computer is a critical safety feature designed to remind divers of their current depth in relation to the necessary ascent guidelines. Exceeding the decompression ceiling increases the risk of nitrogen bubbles forming in the body as a result of ascending too quickly from deeper depths while still supersaturating the tissues with nitrogen, which can lead to serious health complications. Maintaining awareness of the decompression ceiling is essential for diver safety, and the downward triangle serves as a clear and immediate warning to prompt corrective actions. Other indications, such as being safe to surface or within limits for safety, would not trigger such a warning, making the downward triangle an important marker for diver safety during the ascent phase of the dive.
