The dawn of a new era. A pneumatically balanced 2nd stage regulator under $400.00!  The Magnum Pro Regulator uses the same technology and design that has earned the Brut brand name 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.  Totally-redesigned to provide outstanding breathing performance, the Magnum maintains dedication to rugged reliability combined with ease of maintenance.  The Magnum has been the overwhelming favorite for entry level applications for decades because of its simple reliability.

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 Magnum Second-Stage boasts a large diaphragm and exhaust vale for optimal response to inhalation and decreased exhalation resistance. Pneumatically balanced 2nd Stage - The pneumatically balanced regulator ensures you get the same amount of air delivery whether you are at 3,000 psi or 500 psi, (200 bars or 30 bars) improving the diving experience. Single valve tube construction - The single construction creates a precise channel for the valve to operate. Co-Molded mouthpiece - The large co-molded mouthpiece uses two different silicone compounds and colors to reduce jaw fatigue.

Magnum's precision Delrin lever and resilient silicone rubber seat give smooth effortless breathing. Its high impact glass-filled polyamide housing for rugged applications make the Brut regulator one great choice for any avid diving enthusiast. Second Stage is equipped with a dive/pre-dive venture switch that helps prevent free flow of the 2nd Stage when surface swimming, entries from boats or diving against a current. The Regulator is equipped with a 3/8" threaded 31" (78.75 cm) low pressure hose, is nitrox compatible to 40% oxygen out-of-the-box", and comes with an owner's manual.
