What is one of the primary benefits of using Nitrox in diving?

One of the primary benefits of using Nitrox in diving is the ability to achieve longer bottom times. Nitrox, a mixture of nitrogen and oxygen that contains a higher percentage of oxygen than regular air, reduces the amount of nitrogen in the breathing gas. Since nitrogen is the gas primarily responsible for nitrogen absorption in tissues and the resulting risk of decompression sickness, using a gas with a lower nitrogen content allows divers to stay at deeper depths for longer periods before they reach their no-decompression limits. As a result, divers can maximize their time exploring underwater environments.

Interestingly, while shorter surface intervals may benefit divers using Nitrox, they are not an inherent advantage of Nitrox itself; rather, that comes from managing dive profiles with respect to overall nitrogen exposure. Therefore, it isn't accurate to claim that Nitrox use universally guarantees shorter surface intervals or higher dive weights, as these factors depend on specific dive plans and profiles. The focus on longer bottom times highlights the significant advantage of using Nitrox for recreational diving, enabling divers to enjoy more extended exploration and engagement with the underwater environment.
