Nitrox Diver

The first step on the nitrox ladder, the IANTD EANx Diver program is designed to provide recreational divers with a safer breathing medium for the sport diving range. Divers may elect to dive the EANx on air tables, EANx tables or computers. This course covers the use of EANx mixes in the range of 21% to a maximum of 40% oxygen.

The IANTD EANx Diver program covers dives in the 12 to 39 meters (40 to 130 feet) depth range with the emphasis on using EANx 32 & 36. The program may be taken on its own or combined with a variety of IANTD Advanced or Specialty Diver training programs.

It is not necessary to carry out dives to qualify as an IANTD EANx Diver, but is it recommended that divers perform two dives on an EANx mixture of between 24% and 40% oxygen.
