Rating: Another solid Sherwood regulator
Reviewer: MICHAEL K.
Very solid 1st and 2nd stage. Ive owned many Sherwood regulators over the years and their quality and durability have kept me coming back. The Blizzard has not disappointed me thus far. I dont do extreme cold water diving so I cannot comment on its functionality there, but it has performed very well in moderately cold water (62F-68F). The second stage is a bit heaver than others Ive used, but underwater its unnoticeable.

The Blizzard has been a standard for divers in the 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. The Blizzard maintains all the key features of previous models; heat retentions vanes, environmentally sealed first stage, the reliability that divers have come to depend on, and the serviceability technicians appreciate. This Blizzard however comes with dramatically improved breathing performance, enhanced cosmetics, and even more exciting, a new more competitive price point.
