Which system can be used to track diving time and depth during Nitrox dives?

The use of dive computers specifically programmed for enriched air is essential for tracking diving time and depth during Nitrox dives due to their advanced features and customization capabilities. These dive computers are designed to account for the characteristics of Nitrox mixtures, allowing for more precise tracking of no-decompression limits, ascent rates, and safe operational depths.

While mechanical dive tables can provide estimates for bottom times and surface intervals, they do not adapt to real-time changes in depth or time like a dive computer can. Standard dive watches, while useful for keeping track of time, do not provide critical data about depth, dive profiles, or Nitrox-specific calculations. Manual note-taking, although a viable method for recording dive data, is not practical for real-time monitoring during a dive, making it less effective than a dive computer.

In summary, the dive computer specifically programmed for enriched air optimally enhances safety and dive planning, which is why it is the most effective tool for tracking diving time and depth during Nitrox dives.
