Hollis – Prism 2 Dive Surface Valve (DSV)
The Dive Surface Valve (DSV) is a standard feature on the Hollis Rebreathers PRISM 2. The DSV allows divers to manually open and close their mouthpiece to control their breathing on the loop. Proper use of the DSV helps prevent water from entering the rebreather when the mouthpiece is not in use.
