Enriched Air (Nitrox) Diver Specialty

Your dive time can be limited by the nitrogen in the air you breathe. By using enriched air (Nitrox), you can reduce the nitrogen in your breathing mixture, and in doing so extend your no-decompression dive time.

This Speciality is designed to extend your knowledge and skills in the use of oxygen enriched gases for Sport Diving. It develops the knowledge required to plan, analyse and use an Enriched Air Nitrox breathing gas mix for recreational no decompression diving.

This speciality can be run for any certified diver who has the equivalent of RAID Open Water 20.

You’ll learn about the use, benefits, hazards and planning considerations for using gas mixes with 22% to 40% oxygen, enriched air dive planning and the procedures you need to understand to obtain and analyse nitrox fills and dive safely with it.

There are two optional nitrox training dives which are recommended but not necessary. Please ask for details.
