The MAGNUM PRO is now a pneumatically balanced 2nd stage regulator. It uses the same technology and design that has earned the BRUT worldwide recognition for durability and reliability, bur the MAGNUM PRO goes a step further with an added 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 while at the surface or in shallow water to stabilize the regulator for better manageability.

  • 1st stage: The T-shaped design reduces regulator profile when mounted on tank minnimizing opportunity to make contact with the back of the head.

    To keep the internal parts of the MAGNUM PRO free from dirt, that can cause it to malfunction, it is completely environmentally sealed. The piston/spring chamber is surrounded by a membrane. This membrane doesn't move the piston like a diaphragm design 1st stage would, it's purpose is solely to seal the chamber without using sticky grease or oils while allowing the air pressure inside the chamber to adjust according to the ambient pressure, thus adjusting spring tension and creating a balanced 1st stage. A pneumatically balanced regulator ensures you get the same amount of air delivered whether you are at 3,000 psi or 500 psi thus improving the diving experience.

    Our personal note: all SHERWOOD regulators except the SR2 have the same 1st stage.

    2nd stage: With the 2nd stage being pneumatically balanced as well, the SHERWOOD MAGNUM PRO is breathing effortless during all stages of the dive. The diver operated flow control switch (Venturi system) provides performance adjustments at the surface and at depth

    A large co-molded mouthpiece uses two different silicone compounds and colors to reduce jaw fatigue.
