Prerequisites: Nitrox Gas Blender, Minimum 18 years old

This course builds on what you learnt in the TDI Nitrox Gas Blender course. (The TDI Nitrox Gas Blender course and the TDI Advanced Gas Blender course can be combined) During the TDI Advanced Gas Blender course you will learn how to blend Trimix gasses (Oxygen, Helium and Nitrogen). You will learn about the properties of Helium and why it is used in technical diving. You will also learn about the different kinds of Trimix and how to top Trimix gasses to achieve a different Trimix gas or how much of an existing Trimix gas you have to empty before you can mix a different desired Trimix gas with minimal Helium waste. During this course you will also learn how to use gas blending software and you will use it as part of this course. After you successfully complete this course you will be certified to mix all Nitrox and Trimix gasses for Nitrox and Trimix divers.
