Enriched air diving is becoming extremely popular worldwide and now PADI has a program that allows recreational divers the opportunity to enjoy the extended no decompression time offered by enriched air. The course will educate students to the benefits of diving enriched air blends of up to 40% oxygen (vs. 21% oxygen in air). One night of classroom will teach students the various methods of creating enriched air and the special tables and procedures that must be followed. At the conclusion of the academic portion of the course students will be given two free nitrox fills to try it out for themselves.
