IANTD: Brand new rebreather diver w/zero previous deco experience - can include advanced EANx / ART (advanced recreational trimix) at the same time as CCR diver. Limitations: 140' (air dil) or 170' (ART), light deco (~10-15 minutes)
Interesting. So there is a 1 step training route from OC rec to CCR light tech. For someone who has to travel for training, this is appealing. Also 170' ART CCR with 15 min deco actually gives quite a lot of diving opportunities.
