This demonstration video goes over the features of the Oceanic EOS Regulator with Dry Valve Technology. The EOS regulator has the smallest and lightest second stage ever produced by Oceanic. It also features the patented DVT (Dry Valve Technology) which eliminates moisture and contaminants from entering your regulator. The Orthodontic mouthpiece alleviates jaw fatigue by easing bite needed to hold regulator. The EOS is Nitrox compatible to 40% (the recreational limits of nitrox).
