I've been told many times by very experienced divers that unbalanced first stages are not good at depth.
From what I understand, all first stages are "balanced" with respect to ambient pressure. At a given tank pressure, all first stages will deliver constant IP no matter the depth.
If a first stage is "balanced", it will also deliver constant IP no matter the tank pressure.
Is this correct so far?
I dove unbalanced first and second stages in the past. Sure enough, they became harder to breathe below 60 ft. I always assumed this was due to depth, but overlooked that of course tank pressure would also be lower at that point in my dive. I was shore diving and it took a bit of time to reach 60 ft from shore, which means tank pressure would have been lower.
