• Unique 4X Yoke design – tighten or remove from tank with one turn.
• Minimalist yoke design is optimized to use the least amount of material for the lightest weight possible.
• Atomic Aquatics exclusive balanced Jet Seat high-flow piston.
• Freeze-protected and factory-sealed to prevent outside contamination from silt and sand.

Second Stage:
• Fresh take on front exhaust design with exhaust valve and inhalation diaphragm both mounted in the front center of the regulator.
• Bold narrow-width case architecture with fluid lines and sweeping flexible front purge cover that integrates seamlessly with exhaust deflectors.
• Variable Lift Cam with near frictionless action lever increases lift at high demands to provide high flow with low inhalation effort.
• Atomic Titanium Seat Saving Dynamic Orifice automatically retracts away from the seat when not under air pressure to extend service life, maintain crisp like-new performance and prevent damage during storage.
• Adjustable venturi nozzle gear-driven tuning with soft-touch lever.
• Low-friction cap at the cam surface.
• Coaxial diaphragm and exhaust valve for 360º breathing effect.
• Hose features the Atomic exclusive patented all-Titanium Comfort Swivel now with less friction and smoother movement.
• Extended silicone exhaust tee is uniquely designed with a sweeping flexible front purge cover and soft rubber exhaust deflectors that route the exhaust away from and behind the divers field of view.

The ultimate "connoisseurs" natural breathing regulator! Atomic Aquatics engineers reimagined the rather unconventional front exhaust regulator design to create the most natural and effortless breathing regulator for all diving attitudes or positions. Traditional rear exhaust regulators have more breathing resistance in certain dive positions, like looking up. The TFX gives divers enhanced and sophisticated air delivery with dramatically reduced inhalation effort compared to all other regulators on the market.
