Dive for Longer

Want the chance to dive for longer, exploring the wrecks or reefs you’ve jumped in to see? The PADI Enriched Air (NITROX) Diver Specialty is just the solution you’ve been looking for! If staying down longer and getting back in the water sooner sounds appealing, then the world’s most popular PADI Specialty course is where it starts.

Diving with Enriched Air (Nitrox) allows you to extend your no-decompression limits and have shorter surface intervals. This is a great benefit for all dives and especially if you are planning a ,ulti dive- multi day dive trip, such as a liveaboard. On the PADI Enriched Air (NITROX) Diver specialty you will learn how to plan and execute dives using 22-40% oxygen using dive computers.

The PADI Enriched Air (Nitrox) Diver specialty course consists of knowledge development and practical exercises followed by two OPTIONAL open water dives. Initially you’ll complete some self study using the PADI Enriched Air manual and DVD. You’ll then attend a classroom session with a PADI instructor, who will review your learning and carry out some practical exercises with you before completing a short quiz and course exam.

You may join us to complete two optional open water dives using Enriched Air (Nitrox). This enables you to plan, conduct and experience Enriched Air dives, including analysing your gas and completing your logbook at the end.

This course will also count towards the prestigious PADI Master Scuba Diver rating and the first dive of this Specialty course may count towards the PADI Advanced Open Water Diver Certification. 

Basic Course: £120

Standard Course: £195

Deluxe Course: from £367 (up to £1195)

Executive Option: additional £100 on Basic, Standard or Deluxe Course fee.

Knowledge Development 

Enriched Air (NITROX) is any gas blend that has more Oxygen than air. Using your course materials (manual or electronic equivalent) you’ll learn why diving with air that has higher oxygen and lower nitrogen content gives you more bottom time.

You’ll meet your instructor at the NHDC classroom to find out more along with enriched air equipment and dive planning considerations.

During a practical session, course exam and two optional scuba dives, you’ll:

  • Discuss managing oxygen exposure.
  • Practice analyzing oxygen content in your scuba tank.
  • Set your dive computer for diving with enriched air nitrox.


You will also learn:

  • Techniques for getting more dive time by using enriched air nitrox
  • How to plan dives using enriched air and how to calculate your maximum depths, dive times, and optimal enriched air blends for any given depth.



Open Water Dives

While not mandatory for this course, you can take up the option to complete 2 dives using NITROX any time we’re in open water and put the theory into practice.

We’ll provide everything you need. We pride ourselves on ensuring there are no hidden costs.

As this is a mostly classroom based course, there is nothing you need other than a Dive Computer. Don’t yet have your own? Don’t worry! Rental of one of ours for the theory (and open water dives) is included in the course price. That said, with discounts available on our range of Suunto Dive computers, only to our Enriched Air NITROX course students, now’s the time to get one of your own!

Opting for the two open water dives? Rental of essential equipment is included in that price too!

As this is a classroom based course, this can be held all year round! Highly recommended for dive trips with multiple dives planned on multiple days.

Knowledge Development can be completed at your own pace but will be reviewed with the NHDC team at our Dive Centre before you go on to complete some further training plus dive planning exercises and the course exam.

The optional two Open Water dives can be arranged and completed on a convenient date whenever we’re in open water, however, we have arranged a few dates to help.

New Horizons aims to be flexible with arranging courses to suit your schedule so if the scheduled dates are not convenient please give us a call to discuss suitable alternatives.
