Nitrox

Cristalsub runs Nitrox through both FEDAS and SSI pathways, with the option for online delivery — they ran at least one online-only Nitrox course during the COVID period, which suggests the theory component is well adapted to remote format. For divers already certified and looking to extend bottom time or run multiple dives a day, this is the logical next step.

The course is available as a standalone specialty without requiring you to be mid-way through an advanced or rescue track. Given the club's focus on travel — they've done liveaboard trips to Indonesia and regular multi-dive days in the Red Sea — nitrox qualification fits the practical reality of how their members dive abroad.

Delivery is in Spanish primarily, with English and Italian available depending on which instructor leads. No specific price is published; contact [email protected] for current rates.
