Fantastic time!! I’ve been wanting to get my open water license for a while and the team at Oyster Diving were super helpful and supportive! I would fully recommend!




Enhance your diving experience by extending your bottom time and reducing surface intervals with the PADI Enriched Air Nitrox course. This course enables divers to use Enriched Air Nitrox, a mix with higher oxygen content, which decreases nitrogen absorption and leaves you feeling more energetic after a dive.
The Enriched Air Nitrox training enables you to stay underwater for longer, making it ideal for exploring wrecks like the Thistlegorm or observing marine life at your leisure. If you plan to do multiple dives in a day or throughout your holiday, using Nitrox helps you feel less fatigued—a benefit confirmed by many dive guides and instructors.
The practical session focuses on analysing the oxygen content in your scuba cylinder, logging the results accurately, and setting your dive computer for the specific oxygen mix. These practical skills can be conducted at any of our pool locations, open water locations, or during one of our club trips. Upon successful completion, you will receive a PADI Enriched Air Diver certification card, enabling you to use Nitrox worldwide.
We offer the practical components of the course at various locations including Mercers Lake and our pools in Surrey & Berkshire, Soho, London, North London, Buckinghamshire and Hertfordshire, South East London and Kent, Oxfordshire, Brighton, and Sussex.
To enrol, you must be at least 12 years old and hold a PADI Open Water Diver certification or an equivalent certification from another recognised training organisation.
Opt for us to benefit from expert instruction from highly experienced dive professionals. Our flexible scheduling options accommodate both weekend and weekday training.
We provide comprehensive support, from eLearning to practical application, ensuring you are well-prepared and confident. We also offer a wide range of convenient locations, ensuring you can complete your training close to home.

Having not dived for 5 years I was worried that I did not know how to set up the kit and do the dive basics. This course was perfect. I was able to ask all the questions I wanted and the instructor was calm and positive. I completed the course…
