Oceanic Regulator
Recommended is to carry an Octopus with the mouthpiece facing down when
not in use, or to use a mouthpiece plug or cover to prevent free-flow in the event
that it is bumped.
During normal use underwater, a small amount of water collects inside the body
of a standard regulator in a natural reservoir near the bottom. This is normal for
most second stages, and the water is held away from your mouth naturally and
will go unnoticed unless you become inverted or do subaquatic somersaults at
which time you may experience temporary 'wet breathing'.
Water can be purged from the small internal air space of most second stages by
exhaling a small puff of breathing gas into the mouthpiece, or by blocking the
mouthpiece with your tongue and pressing the front mounted purge button to ini-
tiate a flow of breathing gas. (See Omega II for an exception to this general
feature.)
Alpha 7, Gamma, Pony Bottle, and Explorers (Primary and Octopus)
These models are downstream demand valve second stage regulators that are
lighter and smaller than most other primary second stages. They provide breath-
ing gas as you demand it with low inhalation resistance. Breathing effort is fac-
tory set to the average performance level required by most divers.
They are provided with front-mounted purge buttons and orthodontically de-
signed mouthpieces. They can be used as primary second stages or as on octo-
pus. The Explorers model, designed for children, has a smaller mouthpiece, and
the Pony Bottle second stage has a standard mouthpiece.
NOTE: If these second stages are shipped from the factory spe-
cifically as an Octopus, the inhalation effort is set slightly higher
to reduce sensitivity.
Delta 3 and Gamma 2 (Primary and Octopus)
Pre-Dive/Dive Switch (on top):
The Delta 3 and Gamma 2 feature a Pre-Dive / Dive switch located on top of
the body.
 Placing the switch in the left ( - ) position (Pre-Dive) reduces, or eliminates,
the possibility of high volume free-flow when the mouthpiece is not in your
mouth.
 Placing the switch in the right ( + ) position (Dive) provides optimum perfor-
mance during a dive.
