RAPID ADJUSTMENT KNOB
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, from a vessel or dock, or situations
where the regulator is not in your mouth, you may want to turn the knob all
the way in (clockwise) to increase resistance. Do not leave the knob in the
increased resistance position while diving. The common misconception is
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 Zeagle second stages you should be familiar with.
