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.
Prerequisites:
- At least 18 years of age
- Advanced Open Water Diver certification (with Deep Speciality) or TDI Intro to Tech or equivalent
- TDI Understanding Nitrox certification or equivalent
- Show proof of fifty (50) logged dives
Course schedule:
- Independent study online
- One confined water training
- Four (4) open water training dives with two (2) of those dives being deeper than 30 metres
- If Advanced Nitrox is taught in conjunction with Helitrox, a minimum of six (6) dives are required
Training Material:
- TDI Decompression Procedures Student Manual
- TDI Extended Range / Trimix Student Manual
