What's in the box: 1'st and 2'nd Stage Regulators, Low Pressure Hose and Owner's Manual
The Magnum uses the same technology and design that has earned the Brut worldwide recognition for durability and reliability. The Magnum goes further to use a venturi device to reduce breathing resistance at the higher flow rates when it is needed the most. A flow control switch allows the diver to switch the venturi effect off when at the surface or in shallow water to stabilize the regulator for better manageability.
> Innovation at its best is the way to explain the function of the Sherwood first stage regulator. The first stage regulator incorporates Sherwood's dry sealed spring. This simple yet unique design has a flow-by piston that mechanically balances the air of the first stage ensuring excellent breathing characteristics at full or low cylinder pressures. Balanced flow-by piston design, which is a "fail safe" mechanism, with a patented dry seal internal mechanism to keep the intricate components clean and contaminate free no matter what kind of environment you dive it in, constructed from marine grade chrome plated brass for long life and durability.
The dry seal function allows the regulator is increase the intermediate pressure of the regulator without messy oils or grease as with more sophisticated designs. This added benefit makes the regulator virtually uncontaminated from the environment of salt, sand or chlorine internally, which makes it the choice of most repair technicians. The first stage is equipped with two 7/16" threaded high pressure (HP) ports and four 3/8" threaded low pressure (LP) ports for addition of gauges and LP accessories; this is one work horse first stage regulator. Tee - shaped design reduces regulator profile when mounted on tank minimizing opportunity to make contact with the back of the head. First stage has a high capacity inlet filter for smooth delivery of air to the second stage.
The Manum second-stage boasts a large diaphragm and exhaust vale for optimal response to inhalation and decreased exhalation resistance. Magnum's precision-ground stainless steel cam, delrin lever and resilient silicone rubber seat give smooth effortless breathing. Its high impact glass-filled polyamide housing for rugged applications make the Magnum regulator one great choice for any avid diving enthusiast. The Magnum is a dependable downstream demand valve design with a venturi adjustment lever to prevent free flow. The lever has a dive/pre-dive setting. Placing the lever in the pre-dive position will avoid unwanted regulator sensitivity while entering the water from the beach with long surface swims or when jumping off the back of a boat. The regulator is equipped with a 3/8" threaded 31" (78.75cm) low pressure hose, is nitrox compatible to 40% oxygen out-of-the-box" , comes with an owner's manual and is covered by a 24 month limited warranty with an optional free parts for life program (restrictions apply).
