This course is designed to qualify recreational divers to use enriched air ("nitrox") for no stop recreational diving. The program addresses the use of enriched air with 22 percent to 40 percent oxygen, with emphasis on enriched air with 32 and 36 percent oxygen.
The course concentrates on the science behind enriched air diving (EAD); there aren’t any mandatory dives although Premier offer two open water dives for a further £30 so students gain their first experience of EAD with an Instructor.
