IANTD Advanced Recreational Trimix

The foundation program for safe self sufficient diving. The IANTD Advanced Recreational Trimix program covers the core skills from the technical diver training programs including the use of twinsets with central isolation manifolds and decompression skills and procedures using bottom mixes of Recreational Trimix with oxygen contents between 21% and 40% with a maximum pO2 of 1.5 bar, combined with a helium content to yeild an Equivelent Narcotic Depth (END) no greater than 24 msw (80 fsw).

An essential component of this program is equipment configuration which is covered in a series of lectures and practical workshops. The aim being to construct a safe self sufficient equipment configuration that is streamlined, accessible and promotes familiarity. Theory covered includes the END concept, oxygen physiology, oxygen tracking, the use of EANx as a decompression gas, gas switching techniques, partial pressures and best mixes.

This program qualifies divers to dive to 48 msw (160 fsw) and to perform decompression stops utilising EANx decompression mixtures with an oxygen concentration no greater than 1.5 pO2 for a maximum duration of 15 minutes.
