Sherwood SR2

The SR2 regulator continues the legacy the SR1 created. It packs advanced technology into a compact case, employing contemporary styling and utilizing a multitude of cutting edge materials. Superior breathing performance of less than 0.5 joules/liter, W.O.B. at 165 fsw, 62.5 RMV. The SR2 is more technically advanced and more attractive than its predecessor.


The first stage is environmentally sealed featuring a dry-sealed spring chamber, two high pressure ports, five low pressure ports on a 360 degree swivel and is compatible with a yoke or DIN attachment. The second stage contains a SMART demand lever and floating crown which reacts to depressurization and relieves the load on the seat, extending seat life while promoting consistent performance.


1st Stage Features

  • Completely dry and environmentally sealed
  • Five low pressure ports on a 360° swivel
  • Two high pressure ports
  • Two-piece piston for precise optimum balance and intermediate pressure control
  • Available in 300 BAR DIN


2nd Stage Features

  • One touch performance adjustment
  • Pneumatically balanced second stage
  • Super flex hose
  • Nitrox ready up to 40%
  • Large flexible purge cover
  • SMART Demand Lever – relieves load on seat. Extends seat’s life while in storage
  • Improved flexible purge cover

Atomic Aquatics B2

The B2 gives divers a close alternative to the all-Titanium T2. The signature Atomic breathing performance is nearly identical. The B2 is ergonomically designed to be the world’s most comfortable second stage just like the T2. The key difference is the chrome-plated Brass body of the B2 first stage, which is more economical without sacrificing performance. That’s why the B2 has garnered more awards from independent tests and reviews than any other regulator on the market.


The performance of the B2 is truly superior to any other rival. Atomic designed our signature breathing performance into the B2 to give a diver the perfect combination of comfort, style and value. The main design difference? The total weight of the B2 is only 9 ounces more than the T2.


1st Stage Features

  • First stage materials are chrome-plated Brass and 316 Stainless Steel
  • Atomic Jet Seat high-flow piston first stage
  • Optional factory-sealed first stage to prevent outside contamination such as silt and sand and prevent freezing
  • Nitrox ready for mixtures up to 40%
  • Two high pressure fixed ports
  • Five low pressure ports on swivel cap


2nd Stage Features

  • All-Titanium second stage construction same as Atomic T2
  • Patented Atomic Seat Saving Orifice
  • Patented Atomic Automatic Flow Control (AFC)
  • Rapid adjustment knob for manual second stage de-tuning in special situations
  • Polished 316 Stainless Steel Atomic Comfort Swivel
  • A new high-flow second stage case that significantly lowers breathing effort at any depth from shallow water to beyond the limits
  • Dual material second stage cover enables entire front to be used for purge
  • Dual silicone comfort fit mouthpiece with tear-resistant bite tabs
  • 2 year/300 dive service interval

Atomic T2

The T2 is designed to be the best performing and best looking regulator on the market-PERIO


• First and second stage components precision machined from solid billet titanium that is lightweight and corrosion free.
• An “all-Titanium Comfort Swivel” standard on all T2 regulators.
• A new high flow second stage case and lever design that significantly lowers breathing effort at any depth from shallow water to beyond the limits.
• Atomic Aquatics Jet seat first high flow piston first stage
• Nitro ready for maxtures up to 40%(must be dedicated for EAN use)
• Patented Automatic Flow Control (AFC)

Atomic Aquatics M1

The M1 has an expanded performance range to meet almost any diving condition imaginable, whether Recreational or Tech. Whether you’re a recreational diver ready to extend your capabilities or an accomplished specialty diver, this regulator will fulfill virtually any need or diving scenario. The M1 is built on the same platform as the world acclaimed B1 and T1 regulators.


  • High performance breathing: High performance (low inhalation efforts at deep depths and high breathing rates) yet delivers the air naturally and comfortably.
  • Materials: State of the art metals. Monel™ parts are used internally in the first stage for its high strength; corrosion resistance and oxygen compatibility. Type 316 Stainless Steel, Palladium/Zirconium coated Brass, and Titanium are used throughout the second stage.
  • Nitrox ready: Factory ready for Nitrox to 50%, or oxygen mixes up to 80% when special guidelines are followed.
  • Compact first stage design: Features 5-port low-pressure swivel and exclusive “Jet Seat” piston first stage design.
  • Seat Saving Orifice: Exclusive patented Atomic Aquatics feature prolongs the second stage seat life indefinitely, eliminating aggravating leaks and degradations in performance.
  • AFC: (Automatic flow control) Exclusive patented Atomic Aquatics feature automatically adjusts airflow at depth to maintain stable, comfortable breathing.
  • Surge protected front cover: New anti-surge front cover is designed for use in high current situations to eliminate the possibility of free flow due to swift moving water or strong currents.
  • Super wide exhaust deflector: The exhaust deflector has been extended to enhance visibility by better deflection of the exhaust bubbles.
  • Cold water diving: For cold water diving, the first stage is environmentally sealed to prevent entry of water or contaminants. The second stage features a thermal heat sink and improved super-dry exhaust valve.
