The Helitrox course examines the theory, methods and procedures for planned stage decompression diving
utilizing Helium in the breathing mixture. 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 150 feet. The most common equipment requirements, gear set-up, and decompression techniques are presented.
Students are permitted to utilize Enriched Air Nitrox and Helium mixes with no greater than 20% He content, and up to 100% oxygen for decompression diving provided the gas mix is within their current certification level. Breathing gas mixtures containing more than 20% Helium or less than 21% oxygen are not permitted (+/- 1%).
Minimum age 18
Certified as a TDI Intro to Tec (or equivalent)
Certified as a TDI Advanced Nitrox Diver (or equivalent)
Provide proof of a minimum 50 logged dives
Qualifications of Graduates
Upon successful completion of this course, graduates may engage in decompression diving activities
without direct supervision provided:
•The diving activities approximate those of training
•The areas of activities and environmental conditions approximate those of training
•Breathing mixtures do not contain more than 20% He or less than 21% O2 (+/- 1%) and are within their current level
