I have a buddy with a CK and I'm now rather familiar with it, also I have a Shearwater so the upgrade path to the CK is pretty clear.
Phi- are you saying OC Trimix cert would allow me to jump to Mod 3? I still slightly don't understand the "mod" structure, why aren't they called- Recreational Rebreather Diver, Extended Range RB Diver and Trimix RB diver instead? :-)
DAVE- PM sent.

I don't understand the Mod thing either. IANTD has CCR Diver, Normoxic CCR and CCR Trimix. TDI Has Air Diluent, Mixed gas and Advanced mixed gas. But neither will let you do full mix on a SK due to manufactures rating.
