| Normoxic trimix
This question comes from a conversation with my regular buddy last night. Both of us have done BSAC Adv' Nitrox. We want to get an ERD (BSAC or TDI / IANTD) under our belts then get into trimix. With BSAC, ERD is pre-requisite for first trimix course.
BUT......................
Can you do a normoxic trimix course having completed Adv' nitrox or do you still need to have done an ERD.
Cheers
