What is a key benefit of using Enriched Air Nitrox?

Using Enriched Air Nitrox allows for longer bottom times at depth because it contains a higher percentage of oxygen and a lower percentage of nitrogen compared to regular air. The elevated oxygen levels help to reduce the amount of nitrogen absorbed into the body during a dive, which in turn gives divers an extended no-decompression limit. This benefit is particularly advantageous for divers who want to maximize their time exploring a dive site without the constraints of rapidly ascending to avoid decompression sickness.

The other benefits, while relevant to diving, do not specifically address the primary advantages of using Enriched Air Nitrox in terms of operational dive time. For instance, a lower risk of nitrogen narcosis does exist with Nitrox due to lower nitrogen exposure at depth, but it doesn't directly extend bottom time. Improved buoyancy control and increased visibility are not directly related to the use of Enriched Air Nitrox; they relate to different aspects of diving technique and equipment.
