Dear Guys,
I do not think you need to do deep air any more to do trimix.
Legally, I would take it up with the guys teaching.
Does the TDI Extended Range Course still involve an air dive to 55m?
That was the most dangerous dive I ever did!!
I am Cave and Advanced Trimix certified.
Jeff the Darwinian.
