Using enriched air lets you spend longer underwater while reducing nitrogen absorption and fatigue. This Nitrox Diver course in Gosforth gives you the knowledge and confidence to dive safely using oxygen-enriched gas mixes. You’ll gain practical skills in gas analysis, dive planning, and equipment preparation through engaging theory and optional in-water practice.
Sessions begin at the Gosforth dive centre with detailed theory on enriched air diving. Instructors guide you through gas analysis, dive planning, and oxygen exposure limits, ensuring you understand how to safely use Nitrox for recreational dives. Practical examples and calculations are included to reinforce learning.
If you choose to complete the optional in-water dives, you’ll practise gas analysis, cylinder labelling, and equipment setup in real conditions. Instructors provide detailed supervision, correcting techniques and reinforcing safety at every step. This ensures you gain confidence in applying Nitrox theory underwater.
Open water dives allow you to experience Nitrox in a real environment, practising dive planning, monitoring oxygen exposure, and managing enriched air safely. These sessions are tailored to your experience, with instructors ensuring you can integrate theory and practice effectively.
Theory sessions take place at the Gosforth dive centre (NE3 2HY), with optional confined water dives at the 25m indoor heated pool in Seaton Delaval, Whitley Bay (Elsdon Ave, NE25 0BP). Open water dives are held at selected UK sites such as Capernwray Quarry, Ellerton Lake, or Beadnell Bay, depending on experience and conditions.
Each site offers a safe and controlled environment ideal for practising Nitrox analysis and dive planning, giving you confidence in both equipment handling and dive execution.
An Open Water Diver certification (or equivalent) is required, along with a basic understanding of dive planning and equipment use. No prior Nitrox experience is needed — the course is structured to make enriched air diving straightforward.
Instructors provide step-by-step guidance throughout, ensuring you understand both the theory and practical application. Emphasis is placed on safety, enjoyment, and confidence building.
Experienced instructors make technical skills accessible, offering hands-on support and practical examples that build confidence. Sessions are delivered in small groups, allowing plenty of time for questions and individual attention.
Training is structured to balance theory and practical application, helping you leave confident in managing enriched air dives. With access to multiple training locations and flexible options, you gain skills that are immediately applicable in real diving conditions.
Nitrox has a higher oxygen content than standard air, which reduces the amount of nitrogen your body absorbs during a dive. This allows longer bottom times, less fatigue, and safer repetitive dives, particularly for those doing multiple dives in a day.
You’ll learn how to plan dives, calculate safe exposure levels, and manage enriched air safely. Instructors explain the theory in practical terms, showing you how Nitrox can improve your diving experience while maintaining safety at all times.
No — you can complete the theory only, which still certifies you to dive with Nitrox anywhere in the world. However, completing the optional confined and open water dives gives practical experience in cylinder analysis, gas management, and using Nitrox in real conditions.
These sessions help consolidate your knowledge and allow you to apply theory safely. Instructors provide hands-on guidance and feedback, ensuring you are confident in both preparation and execution of Nitrox dives.
The full course is typically completed in one day if you include the optional dives. The online theory component can be completed at your own pace before attending in-person sessions, allowing flexibility for your schedule.
Time is allocated to practise calculations, gas analysis, and dive planning thoroughly, with breaks for discussion and instructor feedback to ensure knowledge retention and skill development.
Standard scuba equipment suitable for recreational diving is required for the optional dives. Nitrox analysis tools, cylinders, and labelling equipment are provided during the sessions.
Instructors demonstrate proper cylinder handling, analysis, and labelling. This hands-on experience is critical to understanding enriched air diving and ensures that you can apply your skills safely and confidently on future dives.
Nitrox certified divers can dive at centres and liveaboards worldwide that allow enriched air use. It is especially beneficial for multi-dive days or holiday destinations offering multiple dives in succession.
You’ll leave the course confident in both theory and practice, prepared to plan and execute Nitrox dives safely. Instructors also provide advice on how to integrate Nitrox into your personal dive plans effectively.
