What might happen if you make a repetitive dive without setting your enriched air computer correctly?

When making repetitive dives with enriched air, it is crucial to set your enriched air computer accurately for the specific blend of gas you are using. If you fail to do this and simply assume that your computer will automatically adjust to the current dive gas, you risk inaccurate calculations related to nitrogen exposure and dive times.

In particular, if the computer does not recognize the new blend after a repetitive dive, it may continue to use the settings from the previous dive, leading to potential overexposure to nitrogen. This can happen with various diving computer models. Therefore, having the computer continue with the previous enriched air blend is a possible consequence of not setting it correctly. Ensuring that the computer reflects the current dive's gas mixture is essential to maintaining safe dive limits, avoiding excessive nitrogen loading, and preventing possible decompression sickness.

Models that only default to error modes or do not recognize the previous blend may not provide the proper parameters for your dive, which can lead to confusion and unsafe diving practices. The importance of proper programming and understanding your computer's features is vital for safe and effective diving.
