Why is it important to set your dive computer correctly before diving?

• A. To adjust for changing water currents
• B. To keep track of your dive logs
• C. To ensure accurate depth and nitrogen calculations
• D. To program in personal dive preferences

Answer: (C)

Setting your dive computer correctly before diving is crucial because it ensures accurate depth and nitrogen calculations. A dive computer tracks your depth during the dive and calculates how long you can safely stay at various depths based on nitrogen absorption, which is influenced by your dive profile. If the dive computer is not set correctly, it can lead to erroneous calculations, potentially increasing the risk of decompression sickness or other dive-related complications. Ensuring that your computer reflects your current dive conditions and personal variables allows for safer diving practices and adherence to no-decompression limits.
