Diver adjustable inhalation effort:

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. 

A simple twist of the GT 3s adjustment knob enables 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.

Patented Dynamic Adjustment:

A common objection to adjustable second stages is that divers cant 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 require you to manually increase resistance as ambient water pressure is reduced to prevent free-flow.
