Recreational Trimix Diver

The IANTD Recreational Trimix Diver program provides Sport Divers with a safer breathing medium within the depth limits of sport diving (39 meters/130 feet), whilst utilising helium to give an Equivelent Narcotic Depth (END) of between 12 and 24 meters (40 and 80 feet). The diver may elect to dive the ‘mix’ on IANTD Recreational Trimix tables or computers.

The IANTD Recreational Trimix Diver program may be taught as a single course or combined with a variety of IANTD Advanced or Specialty Diver programs. The program qualifies divers to perform no stop dives using Recreational Trimix Gas mixtures within the limits of the existing qualification level to a maximum depth limit of 39 meters(130 feet).
The program covers all Recreational Trimix gas mixes from 28% to a maximum of 40% oxygen and Helium concentrations yielding an END no greater than 24 meters (80 feet) emphasizing the use of 30/25 trimix.
