    Just for kicks I used this a while instead of my regulator and it is great! My reference on the same dive is a Cressi Elipse that was hard to purge and not so easy to breath from. The hose is REALLY easy to see even when your buddy is not close to you and on limited visibility. No leaks. Great for emergencies!

              I use Aeris ION regulator as primary, which is one of most easy-breathing regulators in that grade.
              .....and This 321 octo is easier to breathe than ION!! I think this explains everything.

              But you have to remember not to pulge at shallow and surface. it will start to freeflow if you do, of course it can be stopped easily by move mouth piece side downward.

                  Shopper  Why Did You Choose This?
                  BRANT H  Totally awesome Octo! Why use a cheapo Octo when your dive buddy's life may depend on it.
                  GEOFF S  Can you supply a replacement cover for the air flow adjustment wheel on this reg? As far as I can tell I am missing only the end cover. Don't you just love rough boat rides?
                  GEOFF S  Thanks Joe - it looks like its just the end cap and possibly whatever mechanism holds it on.
