TDI Advanced Trimix Course

The TDI Advanced Trimix Course provides the training required to competently and safely utilize breathing gases containing Helium for dives that require staged decompression, utilizing Nitrox and/or Oxygen mixtures during decompression to a maximum depth of 300 FSW.

Divers interested in the TDI Advanced Trimix Diver Course must have TDI Advanced Nitrox and TDI Decompression Procedures. TDI Extended Range, TDI Entry Level Trimix or equivalent certifications are also required. Individual must be 18 years of age and have a minimum of 100 logged dives of which 25 must be deeper than 100 FSW.

Open Water Dives

Open water skills will include properly analyzing gas mixtures, demonstrating pre-dive planning, and executing the planned dives within the limits, planning for contingency
situations and problems, staged decompression, proper deployment of lift bag and reel, simulated emergency gas sharing, deployment of backup regulator or bail-out SCUBA system, switching and isolating a malfunctioning regulator. Maximum training depths will not exceed 300 FSW.

Equipment Requirements:

Mask, fins, snorkel, buoyancy compensating device with power inflator and proper lift for equipment configuration, weights, cylinders properly cleaned and marked as required for EAN use and appropriate to air consumption and dive plan with dual outlet manifold, travel mix cylinders and/or decompression mix cylinders appropriate to air consumption and dive plan and marked as required for EAN use each with submersible pressure gauges, drysuit inflation system, regulators properly marked and cleaned as required for EAN use with long hose second stage, submersible pressure gauge, redundant depth gauge and bottom timer and/or dive computer, primary and redundant light sources, exposure suit proper for diving environment, primary and redundant line cutting devices, reel adequate for maximum planned depth, 50 pound minimum rated lift bag, and slate.
