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.

Breathes great for an octo.

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.
