How can using EANx contribute to increasing dive tourism?

Using Enriched Air Nitrox (EANx) can significantly enhance the diving experience by extending the allowed bottom time at given depths, allowing divers to explore underwater environments more thoroughly. The increased oxygen content in EANx reduces the proportion of nitrogen in the breathing gas, which helps to mitigate the risks of nitrogen narcosis and decompression sickness. This means that divers can remain at depth for longer periods compared to standard air while maintaining a safer profile. As a result, divers are likely to enjoy their dives more and experience the unique marine life and underwater features that dive destinations have to offer. This enhancement in the quality of diving experience can lead to increased dive tourism as more divers are drawn to locations that are known for their diverse and captivating underwater ecosystems.

The other options do not accurately reflect the benefits or implications of using EANx. Promoting deeper dives without training undermines safety protocols necessary for conducting dives safely, while limiting dive sites based on oxygen content is not a realistic approach, as many dive sites do not have variable oxygen levels. Furthermore, avoiding safety regulations is counterproductive and poses risks to diver safety and overall dive industry integrity.
