The SR2 Regulator builds on the SR1's legacy by combining advanced technology, compact design, and contemporary styling with cutting-edge materials to deliver a high-performance regulator system. Boasting superior breathing performance and a sleek appearance, the SR2 surpasses its predecessor in every way.

The SR2's first stage is one of the few truly balanced regulators available today. Most balanced piston regulators attempt to be pneumatically balanced but fall short due to the wear caused by their sharp knife-edge piston sealing surfaces. Sherwood addressed this issue by developing a two-piece piston that increases the sealing diameter without using a knife-edge surface. This design eliminates excessive wear and creates the first truly pneumatically balanced flow-thru-piston first stage regulator, ensuring high-flow capacity and rapid response to second stage demand.

Traditional piston regulators allow water to enter the main spring cavity, which can introduce contaminants that deteriorate performance. Sherwood resolved this problem by creating a sealed dry spring chamber that prevents water and contaminants from entering the regulator's interior, thus maintaining optimal performance. The SR2 first stage has five low-pressure (LP) ports on a 360 Degree swivel and two high-pressure (HP) ports for ideal hose routing, and is made from marine-grade chrome-plated brass, being nitrox ready up to 40% out of the box.

The SR2 features a pneumatically balanced second stage with a SMART demand lever and floating crown, extending seat life and ensuring consistent performance. A unique single adjustment point simultaneously sets opening effort and high flow performance with one motion, eliminating the need for separate adjustments. The SR2 control knob is optimized for easy location and operation, even while wearing gloves. With an ergonomic, weightless-in-water design, the SR2 second stage provides maximum comfort. The regulator comes with a 3/8" threaded 31" (78.75 cm) low-pressure hose and owner's manual.
