How frequently should dive tables be referenced when using Nitrox?

The correct practice is to reference dive tables continuously as specifics of the dive change. This approach is important because various factors can affect the dive plan, such as changes in depth, time spent at each depth, and variations in Nitrox mixtures.

By continuously referencing dive tables, a diver can ensure they remain within safe limits and can manage their exposure to nitrogen more effectively. This allows for real-time adjustments based on actual dive conditions, thus optimizing safety and reducing the risk of decompression sickness.

This proactive method supports the diver in being aware of their current nitrogen load and aids in maintaining control over any potentially risky situations during the dive. In contrast, other options suggest limited or no use of dive tables, which could lead to unforeseen risks during the dive.
