One Op employee didn't think a Tec c-card w/100% o2 rating was good enough for Nitrox...he was overridden by his boss. Aside from that, no issues
I would love to hear the conversation after that between them

all mine have been local dives either shore or boat -- only get asked to see the nitrox card when getting fills really but I book the boats thru the shop -- at most then have to fill out the info on the waiver.
