The Sherwood Scuba 9000 Series Oasis Pro and Blizzard Pro 2nd Stages feature an uniquely designed valve body. The Blizzard Pro has been tested to withstand extremely cold water conditions and the Oasis Pro also includes the Sherwood Scuba's legendary moisture retention vanes, a design proven to reduce the dry mouth sensation during dives. Due to its one-tube construction design the internal components have a consistent inner surface to travel through.  Our 9000 series 2nd stages build upon the Sherwood principles of rugged reliability combined with ease of maintenance & adding high performance breathing on extreme environmental conditions.
