TFX. IT’S ALL ABOUT ATTITUDE. 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.
