Description
The Blizzard's 1st stage is entirely dry and environmentally sealed, preventing icing and maintaining cleanliness. Its Piston 1st stage design doesn't require gels or liquids to create a seal. With 30 years of popularity among cold water divers and Public Safety Dive Teams, the Blizzard has become known for its reliability and ease of service. This latest model offers improved breathing performance, enhanced cosmetics, and a competitive price point.
Sherwood's first stage regulator features a dry sealed spring and flow-by piston design that mechanically balances air, ensuring excellent breathing at full or low cylinder pressures. The dry seal function allows for intermediate pressure increase without messy oils or grease, keeping the regulator free from contaminants like salt, sand, and chlorine. It includes two 7/16" threaded high-pressure (HP) ports and four 3/8" threaded low-pressure (LP) ports for gauges and LP accessories.
The second stage boasts a large diaphragm and exhaust valve for optimal inhalation response and reduced exhalation resistance. Its precision-ground stainless steel cam, Delrin lever, and resilient silicone rubber seat provide smooth, effortless breathing. The Blizzard also features a venturi adjustment lever to prevent free flow and has a dive/pre-dive setting for different entry scenarios.
Cold water divers will love the exclusive second-stage heat-retention vanes that keep the valve mechanism warm, reducing the risk of freeze-up. These vanes also keep your mouth cool and comfortable. The heat/moisture retention vanes collect vapor from exhaled air and return it to the diver upon inhalation, promoting hydration and reducing dry mouth. The Blizzard comes with a 3/8" threaded 31" (78.75cm) low-pressure hose, is nitrox compatible up to 40% oxygen, and includes an owner's manual.
