Advanced Recreational Trimix Diver

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 meters (80 feet).

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 meters(160 feet) 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.

Prerequisites:

• You must be qualified as an IANTD Recreational Trimix Diver or Nitrox Diver and IANTD Deep Diver with proof of a minimum of 30 logged dives or sufficient experience to satisfy the instructor that the student has the ability and knowledge to continue into this level of training.

• You must be a minimum of 15 years of age with a parent or guardian authorisation, or a minimum of 18 years of age.

Equipment Requirements:

• IANTD Advanced Recreational Trimix Student Kit.

• 1 twinset with isolation manifold

• 1 safety or decompression gas cylinder rigged as either a pony or stage cylinder. Gas cylinders must be oxygen clean and oxygen serviceable where needed.
