Enriched Air Nitrox

The Enriched Air Nitrox specialty at Orca Diving covers the theory and safe practices for diving with oxygen-enriched gas mixtures. The centre has the equipment needed to support nitrox use on site — the BAHUER compressor and their operational setup handles cylinder fills. At 180€ it is one of the most straightforward specialities to add to a certification record.

The course is primarily theory-based — analysing nitrox mixes, calculating maximum operating depths, adjusting dive planning for higher O2 fractions. The classroom at Club Nàutic l'Escala is used for the academic sessions. The practical component, where students analyse their own cylinders and plan accordingly, runs alongside the centre's normal dive operations.

For divers doing multiple dives per day on the Janity across the Medes or Cap de Creus zones, nitrox extends no-decompression limits on repetitive dives — a practical advantage for anyone running a bono package across several days. The speciality is relevant both for the local diving programme and for travel to destinations where nitrox is standard.

The Nitrox certification is accepted across SSI, FEDAS and FFESSM affiliated operations. Combined with the centre's BAHUER compressor setup, certified students can continue using nitrox on subsequent dives at Orca Diving through the season.
