What should divers always carry when using Nitrox?

When using Nitrox, divers should always carry an oxygen analyzer and a logbook. The oxygen analyzer is crucial for verifying the exact oxygen percentage of the gas mixture being used. Since Nitrox can have varying mixes of nitrogen and oxygen, ensuring the correct mix avoids the risks of oxygen toxicity or unintentional use of a gas with a higher percentage of oxygen than intended for the dive profile.

The logbook serves an important function in tracking dive profiles, including depth, time, and the specific gas mixtures used. This documentation is essential for both safe diving practices and for planning future dives, particularly when considering residual nitrogen and oxygen exposure from previous dives. It helps in adhering to safe no-decompression limits and managing cumulative gas load effectively.

Having an accurate understanding of the gas mixture and maintaining detailed records are integral components of safe diving practices when using Nitrox, which are specifically aligned with the training divers receive.
