This course provides the information necessary to utilize EANx as a breathing medium. The course may be taught as a stand-alone specialty course to certified divers or integrated into other NAUI certification courses. Upon successful completion of this course, graduates are considered competent to utilize EANx (up to EAN40) in open water diving activities without direct supervision, provided the diving activities and the areas dived approximate those of training.

This course includes a digital package and upon completion a NAUI digital certification card. If you would like a physical card it is an additional $25. For a physical text book (digital textbook is part of the package) please contact Bill to rent or buy.
