Preventing Air Loss -
To prevent free-flow when the Delta is out of your mouth, or when connected as an oc-
topus second stage, rotate the adjustment knob 'clockwise' several turns. At the sur-
face, place the Delta 3's Pre-Dive / Dive switch in the left (-) position (Pre-Dive) to re-
duce, or eliminate, free-flow.
Remember, increasing inhalation resistance can prevent undesirable air loss. It will
not conserve air while you are breathing from the Delta.
Storage Setting -
At the conclusion of a diving day, or when storing the Delta for any length of time, ro-
tate the adjustment knob 'counter clockwise' until it stops. This relieves excess spring
pressure from the poppet seat increasing its service life.
Immediately prior to the next dive, reset the adjustment to the normal pre dive setting
by turning the adjustment knob 'clockwise'

Omega II and Omega II with Swivel
The Omega II is a high performance servo-valve assisted second stage regulator with a
side-exhaust. Inhalation ports surround the main valve, providing greater surface area,
less resistance to breathing gas flow, and higher flow rates creating more natural, easier
breathing than other types of second stages, regardless of depth.
Due to the Omega II's servo design, a hiss may be heard upon being pressurized. This is
normal for the Omega II.
