What is the primary benefit of using Nitrox for scuba diving?

Using Nitrox for scuba diving primarily provides the advantage of longer bottom times and reduced nitrogen absorption. Nitrox, which is a breathing gas that contains a higher percentage of oxygen and a lower percentage of nitrogen compared to regular air, allows divers to stay at a given depth for a longer duration without increasing the risks associated with nitrogen narcosis and decompression sickness.

With the reduced nitrogen content, divers experience less nitrogen buildup in their tissues during a dive. This aspect is crucial as it lowers the risk of decompression sickness, commonly known as "the bends," when ascending after a dive. By enabling divers to extend their bottom times safely, Nitrox gives them the flexibility to explore more during their dives, leading to a more enriching diving experience.

While other options may suggest benefits that are associated with diving, they do not directly relate to the primary advantages of using Nitrox. For instance, while buoyancy control is important, it is influenced more by other factors like gear and technique rather than the gas mixture. Similarly, while some divers might feel warmer due to the effects of increased oxygen levels on metabolism, this is not a primary benefit of Nitrox. Reducing decompression stops is somewhat related, but the key advantage lies in the extended bottom time
