Sherwood Regulators — Seventy Years of Breathing Easy
Sherwood has been engineering precision regulators since 1955, when its components were trusted inside virtually every diving regulator on the market. Today's lineup carries that same engineering DNA — patented technologies like A2-DC depth compensation, Three Pin Link precision pressure transfer, and the Moisture Retention Vane — combined with modern materials and designs that make Sherwood's regulators among the most comfortable, durable, and reliable in recreational diving.
At DiveCatalog.com, we carry the current Sherwood regulator lineup as an authorized dealer.
The Sherwood Regulator Range
Maximus Pro — The Legend Returns
The original Maximus was one of the most popular regulators of the 1980s and 90s, known for its underarm swivel and extended hose design. The Maximus Pro brings those iconic features back with modern engineering: the 9000 Series first stage with A2-DC (Air-Assisted Depth-Compensation) Technology — a patented system that uses internal pneumatic force to compensate for ambient pressure changes, producing an environmentally sealed, internally dry first stage that responds accurately at any depth. The second stage features a Balanced Valve Body, One-Touch Adjustment, SMART Demand Lever, High Performance Valve Design, and an oversized purge cover. The underarm swivel positions the hose under the arm for a cleaner, more natural breathing position, and the 42-inch extended hose adds flexibility for a wide range of diving configurations. The Wisdom Mouthpiece completes one of the most distinctive and comfortable regulators on the market.
Oasis Pro — Moisture Retention Technology
The Oasis Pro's standout feature is the trademarked Moisture Retention Vane — a design inside the second stage that captures moisture from exhaled air and returns it to the breathing gas stream, preventing the dry mouth and throat irritation that affects many divers on longer dives. A dry, environmentally sealed piston first stage design eliminates the need for gels or liquids to seal the mechanism. The larger diaphragm and purge cover enhance ease of breathing throughout the dive, and a diver-operated Venturi control allows simple in-dive adjustment.
SR2 — The Engineering Achievement
The SR2 holds a specific claim in regulator engineering: it's the only flow-through piston regulator that is both environmentally sealed and internally dry while still incorporating a depth compensation mechanism — a rare combination that requires significant engineering precision to achieve. Sherwood's Three Pin Link (3PL) system ensures precise environmental pressure transfer to the piston for consistent airflow and exceptional breathing at any depth. Available in Yoke and DIN configurations, suitable for warm or extreme cold-water conditions.
9000 Series First Stage
The foundational first stage underlying the Maximus Pro system, also available standalone. Balanced flow-by piston with Sherwood's Dry Seal Spring — a patented dry seal internal mechanism keeping the internals clean and free from salt, sand, and chlorine contamination without oils or grease. Two 7/16" HP ports and four 3/8" LP ports. T-shaped design reduces profile when mounted. Nitrox compatible to 40% out of the box.
Sherwood Octo SR9952 — The Rental Standard
Completely redesigned for outstanding breathing performance while maintaining dedication to rugged reliability and ease of maintenance. The Sherwood Octo has been the overwhelming rental favorite for decades for exactly the reasons that matter in a rental environment: simple, reliable performance and straightforward servicing. Available in both yellow and standard configurations.

Frequently Asked Questions — Sherwood Regulators
What is A2-DC Technology?
Air-Assisted Depth-Compensation — a patented technology in the 9000 Series first stage that uses internal pneumatic force to compensate for changes in ambient pressure, producing a more consistent, responsive breathing experience at all depths without relying on external mechanical levers or diaphragms for pressure sensing.
What is the Three Pin Link (3PL) system on the SR2?
A precision mechanism that ensures accurate environmental pressure transfer to the piston in the SR2 first stage, providing consistent airflow and breathing performance at any depth — the engineering key to making the SR2 the only flow-through piston that's simultaneously sealed, dry, and depth-compensated.
Why does the Oasis Pro have a larger diaphragm than standard second stages?
A larger diaphragm reduces the inhalation effort required to open the demand valve, making each breath easier to initiate throughout the dive, particularly at depth where pressure increases inhalation resistance on standard designs.
Is the 9000 Series suitable for cold water?
Yes — the dry seal internal mechanism specifically prevents contamination from salt, sand, and chlorine without requiring oils or grease, making it well-suited for diverse diving environments including cold water where some regulators experience issues with internal contamination.
