The Oceanpro Osprey II regulator utilises a series of advanced design features that enhance both performance and versatility, breaking new boundaries for the Oceanpro brand and setting this regulator apart from any competitor in its price bracket. The Osprey II is Australian by name and Australian by design. In a country where harsh environmental conditions and regular local diving are the norm, it was critical that we developed a feature-rich product capable of performing dive after dive, in any conditions. Critical performance features such as pneumatically balanced second stage with dynamic in-use adjustment make breathing through this regulator at depth feel as natural as breathing on land. The Osprey II is a pneumatically balanced second stage that reduces breathing resistance to near zero via a balanced valve seat, designed to respond to the slightest inhalation. While a pneumatically balanced second stage may have a similar initial crack opening effort as a mechanically balanced second stage, the spring force in a pneumatically balanced design is much lighter. This results in a lower spring rate, delivering a life-like breathing experience with every inhalation.
