Full review: Scubapro S600 Regulator

The Scubapro S600 is a premium balanced diaphragm first stage regulator paired with a pneumatically balanced second stage, engineered for divers who demand consistent, effortless breathing performance across a wide range of depths and conditions. Building on the proven design lineage of Scubapro's Mark series first stages, the S600 first stage features an environmentally sealed construction that protects internal components from contaminants, silt, and cold water intrusion, making it a reliable choice for divers who explore everything from tropical reefs to cold, murky quarries. The balanced diaphragm design ensures that intermediate pressure remains stable regardless of tank pressure or depth, so air delivery stays smooth and predictable whether you're cruising at ten feet or working at technical depths.

At the heart of the S600 second stage is Scubapro's patented Adjustable Venturi Assist system, which allows divers to fine-tune airflow and switch between predive and dive modes to prevent free-flow on the surface while maximizing performance underwater. The second stage housing is a lightweight, compact design that reduces jaw fatigue during long dives, and the ergonomic mouthpiece and exhaust tee are shaped to minimize bubble interference with the diver's field of vision. A large purge button makes clearing the regulator simple even with gloved hands, and the inhalation effort can be adjusted on the fly, giving divers granular control over breathing resistance to match their personal preference or changing dive conditions.

Constructed with a blend of chrome-plated brass and technopolymer materials, the S600 strikes a balance between durability and weight savings, making it suitable for both recreational travel divers and those who dive more technical or demanding environments. The first stage typically offers multiple low-pressure and high-pressure ports, giving divers flexibility to configure their rig with an octopus, BCD inflator hose, and dive computer transmitter without compromising hose routing. Scubapro's reputation for rugged reliability and serviceability means the S600 is backed by a global network of authorized dealers for maintenance, and its combination of balanced performance, adjustable features, and cold-water readiness has made it a long-standing favorite among divers seeking a dependable, high-performing regulator for years of underwater exploration.
