How should divers monitor their time underwater when using EANx?

Monitoring time underwater when using Enriched Air Nitrox (EANx) is crucial for diver safety and ensuring that they remain within the calculated no-decompression limits. The most effective way to do this is by using a dive computer that is specifically calibrated for EANx.

A dive computer designed for EANx takes into account the specific mix of gases being used, allowing it to accurately calculate no-decompression limits and essential safety stops. It continuously monitors the diver's depth and time, providing real-time data and alerts as conditions change, which helps prevent decompression sickness.

While using a watch to time each dive can provide a basic method for timekeeping, a dive computer offers significantly enhanced safety and accuracy. Intuition is unreliable when it comes to underwater navigation and safety measures, and restricting time monitoring to only during safety stops neglects the importance of monitoring overall dive time. Thus, the use of a calibrated dive computer specifically for EANx is the ideal way to ensure diver safety and adherence to safe diving practices.
