Enriched Air Nitrox Level 2 Practice Test 2025 – Complete Exam Prep

Diving into enriched air nitrox, particularly at a 40% oxygen blend, opens up a new realm of possibilities for scuba enthusiasts. Advancing beyond basic open-water diving, the SSI Specialty Course Enriched Air Nitrox (SC-EAN) 40% Level 2 prepares divers to handle these blends safely and effectively, enhancing their underwater experience. Preparing for the test becomes crucial, and here’s how you can ace it with our strategic guidance.

Why Pursue the Enriched Air Nitrox Certification?

Enriched Air Nitrox, often just called 'Nitrox,' allows divers more bottom time and shorter surface intervals due to lower nitrogen absorption. This translates to extended underwater excursions and enhanced safety margins, especially on repetitive dives. By completing the SC-EAN 40% Level 2 exam, you affirm your knowledge and capabilities in managing specific gas mixtures, dive planning, and equipment handling, making you a sought-after dive buddy.
