Thank you for enquiring about our Nitrox Course   

Here at Divecrew we are able to give you a choice of agencies

Would you like to spend longer underwater and get back in the water sooner?

 The Nitrox specialty is for those wishing to extend their dive profile times, on many dives, underwater time is governed by our no decompression limits. By increasing the oxygen and decreasing the nitrogen content of our breathing gas we can safely increase these limits.

You’ll learn why diving with air that has higher oxygen and lower nitrogen content gives you more bottom time, along with enriched air equipment considerations. During a practical session you’ll:

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

What is included?

Price includes all tuition and materials. This course can also be done digitally online.

Your instructor will guide you through the safe practice of diving on enriched air, which is anything over 21% oxygen. You will learn about maximum and contingency depths for any given percentage; how to test the contents of a cylinder and set your computer from air mode to the correct Nitrox percentage; and how to work out safe diving depths for any given mixture.

Being a dry course this one is great for the colder weather and is a mixture of reading and Knowledge Reviews, PowerPoint presentation, DVD and practical tasks such a completing a Nitrox Fill Log and testing gas. There is a multiple-choice examination for this course.

What is required?

Prerequisites: Age 12+ and Open Water Certification (or equivalent)

Please bring along your dive computer and be familiar with its nitrox function, if you haven’t got one, we will loan you one of our school computers or you can purchase one from us.
