                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.

                      Comments about Hollis Gear Hollis Balanced 321 Octopus with 36" (91cm) Yellow Hose:

                      This Octopus is very complimentary to my Hollis BC and DC 2/221 Regulator. Proven reliable under all dive conditions that is legendary and custom with Hollis Products. The High Visibility Yellow Hose and Purge Front Piece is easily identifiable even in low visibility water conditions. The AVS Pre-Dive/Dive Switch is optimal and well developed to prevent free flow. I would highly suggest this along with any Hollis Product and Oceanic Dive Computers.

                      Questions about this item:

                      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.
                      Joe H  Because it's balanced, is free flow a problem?
                      Joe S  This regulator has a venturi which is easy to control. If this regulator is serviced properly or brand new out of the box, then pushing the venturi away from the mouthpiece will redirect the airflow, preventing any type of free flow. This regulator is a great breather.
