RAPID ADJUSTMENT KNOB
There is only one diver adjustable control on the second stage. It is the rapid
adjustment knob on the side of the regulator that can be used to “detune” or increase
inhalation effort. Under normal use, the knob should always be turned all the way out
(counterclockwise) for the lowest breathing effort. During entries through the surf,
jumping off of a boat, or situations where the regulator is not in your mouth, you may
want to turn the knob all the way in (clockwise) to desensitize it. Do not leave the knob
in the detune position while diving. The common misconception that this will conserve
air is not true and will only make breathing slightly harder. Never force the knob past its
stops in either direction.
FLEXIBLE PURGE COVER
The entire front cover of the second stage is flexible and can be depressed to purge
the regulator.
These regulators operate similarly to others of this type. There are some unique features
of the Atomic Aquatics second stages you should be familiar with.
