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. The Programme employs EANx mixes from 21% oxygen to a maximum of 1.5 PO2 combined with a Helium content that maintains an END no greater than 24 msw may be used.
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.
The purpose of this program is to qualify divers to dive up to 170 fsw (51 msw) and perform decompression stops required dives up to 15 minutes.
