What is a significant benefit of using Nitrox for longer dives?

Using Nitrox offers a significant benefit in that it extends bottom time and reduces nitrogen absorption. When divers use Enriched Air Nitrox, which has a higher percentage of oxygen than regular air, it results in lower levels of nitrogen that are inhaled compared to diving with air. This reduced nitrogen absorption decreases the likelihood of nitrogen narcosis and decompression sickness, allowing divers to safely extend their bottom time without exceeding certain no-decompression limits.

This capability is crucial for divers who wish to maximize their experience underwater while minimizing the risks associated with nitrogen. Remaining aware of how much nitrogen is absorbed during a dive is essential for safe diving practices, making Nitrox an attractive option for those planning longer dives.

The other options do not accurately reflect the primary advantages that Nitrox provides when it comes to longer dive durations and safety with regards to nitrogen exposure.
