He uses terms like "regulators do not flow enough air" and such. Those are not a terms which a guy well versed in regulators would use. Demand regulators deliver air on demand, meaning that they provide only the amount of air that your lungs need. Unless you are extremely deep to the point that the density of the gas that you are breathing cannot flow through the first stage, you can pretty much use most regulators made in the past ten years in most types of diving. I just do not like the "scare tactics" from someone that divers are going to believe because he has a bunch of qualifications. I'm sure he's a wonderful diver.
I think you hit it on the head when you mentioned that english is not his native tongue. Deutsch...
