Enriched Air Nitrox (40%)
With the Enriched Air Nitrox (EANx) certification, divers are able to dive with a higher concentration (up to 40%) of oxygen compared to standard air tanks.
Why is this beneficial? It means:
- Longer bottom times. Diving with Nitrox means you absorb less nitrogen which allows you to stay underwater longer as it lengthens your no-decompression limits.
- Longer repetitive dive times. If undertaking multiple dives in a day, you'll have a longer allowable bottom time on subsequent dives than if you were using air.
- Shorter surface intervals. Breathing less nitrogen shortens the required “off-gas” time needed between dives which means you can get back in the water quicker.
- Less fatigue. This last point is up for debate but many divers claim diving on nitrox makes them less tired than diving on air.
The Enriched Air Nitrox course is conducted as a dry course and with the eLearning done ahead of time, you can easily take the course alongside your guided dives – meaning there's no need to sacrifice underwater time during your dive holiday.
