TDI - Advanced Gas Blender Course

This course provides the training required to competently and safely blend Trimix gasses. In the TDI Nitrox Blender course you learned to blend Enriched Air Nitrox (EAN) which increases no decompression dive times at recreational depths and which is used by decompression divers to shorten their decompression obligations and reduce their chances of DCI.

In this course you will learn why divers use Trimix and how to safely blend Trimix gases. You do not need to be a Trimix diver to undertake this course!

Successfully completing this course will ensure that you can provide accurate Trimix blends to correctly certified divers in a professional and safe manner.

What do I need to start?

  • Be a minimum age of eighteen (18).
  • Show proof of certification of TDI Nitrox Gas Blender or equivalent.
