The TDI Helitrox Course examines the theory, methods and procedures for planned stage decompression diving utilizing Helium in the breathing mixture.
This program is designed as a stand-alone course or it may be taught in conjunction with Advanced Nitrox.
The objective of this course is to train divers how to plan and conduct a standard staged decompression dive not exceeding a maximum depth of forty five (45) metres.
Students are permitted to utilize Enriched Air Nitrox and Helium mixes with no greater that 20% “He” content and up to 100% oxygen for decompression diving provided the gas mix is with their current certification level.
Breathing gas mixtures containing more than 20% Helium or less that 21% oxygen are not permitted.
