SR1 Earns Perfect Simulator Scores
July 2008, Scuba Diving Magazine
Features: The new SR1 from Sherwood Scuba was the standout regulator of this review, offering innovative design, clever features and outstanding breathing performance. The first stage is polished chrome over brass with five low-pressure ports on a turret and two high-pressure ports. It’s a balanced piston design, but with a unique air-filled dry-sealed spring chamber that is completely environmentally sealed. The pneumatically balanced second stage features a single control knob that simultaneously adjusts both the venturi control and breathing resistance. And between dives, a SMART demand lever lightens the load on the valve seat for extended life and performance. Bonus: The second stage also comes with an external fitting for adjusting lever height, making life easier for your technician.
Performance: Underwater, the SR1 delivers dry and effortless breathing in all positions, thanks in part to an oversized exhaust valve, which reduces exhalation resistance. This design helps reduce overall work of breathing, and yielded excellent ANSTI machine scores in all tests. In fact, the SR1 was one of only four regs to earn perfect simulator scores. The flexible front-cover purge provides a forceful clearing action, and the low-profile exhaust tee does a good job of deflecting bubbles, both when stationary and when moving forward in the water.
Bottom line: The SR1 is a solid breather, combining proven regulator design with cutting-edge features for excellent performance.
