The Blizzard has been a standard for divers in cold waters for the last 30 years. It has been the go to regulator for many Public Safety Dive Teams around the country because of its reliability in the colder waters and for its ease of service. In the summer of 2016 we introduce the new Blizzard Pro. The new unit has proven to be as reliable in all environments. With a completely new Valve Design, the new Blizzard Pro comes with improved breathing performance and enhanced cosmetics.
