DYNAMIC ADJUSTMENT
Most downstream demand valve regulators are calibrated during manufacturing to a single,
‘middle of the road’ operation. Whether finning up current at 100+ feet or merely snorkeling
out to the dive site, this factory adjustment may not be optimum for the wide variety of demands
we place on our equipment. Adjustable second stages provide complete control... set the
inhalation requirement to near zero when you need ultimate performance, or tune it for greater
resistance as conditions or preferences change.
A common objection to adjustable second stages is that divers can’t imagine themselves twisting
and turning a knob as they descend and ascend through the depths. If inhalation resistance is set
near zero at depth, your ascent would routinely require you to manually increase resistance as
ambient water pressure is reduced to prevent free- flow. Oceanic’s patented DYNAMIC ADJUSTMENT
features a mechanically balanced valve which automatically maintains your preferred breathing
resistance throughout the dive. Set it once and the valve adjusts to make breathing as easy
at extreme depth as it is at 30 feet - with no additional manual adjustment.
