Nitrox Level 1

The Nitrox Level 1 specialty at Correct Diving runs as a half-day course — compact enough to fit alongside a diving day without losing water time. The base has its own on-site nitrox mixing and fill station, so the practical side connects directly to the equipment students will be using.

The course is explicitly described as useful for cold-water diving and for shortening surface intervals. The Adriatic around Krk is not tropical, and water temperature drops significantly outside the summer months — context that makes nitrox a practical rather than exotic choice for the dives run from this base.

Open Water Diver certification is the minimum entry level (the specialties page specifies participation from OWD). Nitrox Level 2 builds on this course and extends the diver's ability to use the full benefits of enriched air, including longer no-decompression limits. The Level 2 runs approximately one full day.
