Hi,
I have been looking at the different types of first stages and am a little confused. Aqua Lung states that "the balanced diaphragm first stage, by the nature of its design, is environmentally sealed" (see specs on Titan). This is not what I have been seeing for other manufactures. Aqua Lung states that the Legend is an environmental dry system that keeps water out of the main spring chamber. It seems to me that everyone EXCEPT Aqua Lung refers to a 1st stage that keeps water out of the main spring chamber as being "environmentally sealed" and balanced diaphragms which don't keep water out of the main spring chamber are not "environmentally sealed". Is this correct? Does the confusion stem from Aqua Lungs refusal to use consistent language with the industry? Or am I missing something?
