What are the components of a dive computer that are especially important for EANx diving?

The component of a dive computer that is especially important for EANx (Enriched Air Nitrox) diving is its ability to track multiple gases and set the oxygen percentage. This is critical for ensuring safe dives when using enriched air mixtures, which typically contain higher levels of oxygen than regular air.

When diving with enriched air, it's essential to monitor the percentage of oxygen in the mixture to prevent oxygen toxicity, which can occur when the partial pressure of oxygen exceeds safe limits. A dive computer specifically designed for EANx diving has the necessary algorithms to calculate and adjust for the increased oxygen levels while keeping track of depth, time, and no-decompression limits based on the specific gas mixture being used.

While tracking temperature and depth can be beneficial, it is not unique to enriched air diving and does not address the specialized needs of managing oxygen levels. Similarly, photography features, while appealing, are not necessary for dive safety and monitoring in the context of using enriched air. Compatibility with air-dive computers is also not relevant, as EANx computers need additional capabilities beyond what standard air-dive computers offer to safely manage the complexities involved with enriched gas diving.
