Is Nitrox widely available at most dive destinations and liveaboards?

The correct understanding is that while Nitrox has gained popularity among divers over the years, it is not universally available at all dive destinations and liveaboards. Availability can vary significantly, depending on the location and type of operation.

For many popular dive destinations, especially those that cater to recreational divers, the standard fill remains air. While some regions, especially those with a more professional diving infrastructure, might offer Nitrox fills, it is still not a guaranteed option everywhere. Nitrox is more prevalent in regions with a higher concentration of dive shops that cater to technical divers or where divers specifically request it. Hence, it remains relatively rare in many places, making the assertion that it is widely available inaccurate. Understanding the local dive culture and operational offerings is essential for ensuring Nitrox availability during diving excursions.
