The iconic Zeagle first stage is now accompanied by a new high-performance flagship second stage. As a consequence, we now have the finest diaphragm regulator on the market.

We designed approximately 20 distinct enhancements in collaboration with Atomic Aquatics, ranging from internal mechanics and materials to outside controls and aesthetics. Every regulator we've ever developed breathes better, works harder, and lasts longer than the F8. 

1st Stage Features

• Balanced diaphragm design and the environmentally sealed ambient chamber ensure top performance in any condition.
• Redesigned environmental seal cap and yoke knob enhance ergonomics & design aesthetics.
• Percision machined neoflon seat harder more reliable material, keeping you diving longer.

2nd Stage Features

• New inhalation diaphragm provides superior tear strength and improved response time to breathing (super soft silicone molded over a low friction disk).
• Improved exhaust valve ensures dryness and a lower exhalation effort.
• Seat-saving orifice, compliments of Atomic Aquatics, retracts when not in use - extending the life of the breathing tube seat. (#5,803,073)
• Seat comprised of soft silicone molded over a metal insert to deliver the firmness required for an airtight seal while maintaining the necessary elasticity to prevent leaking.
• Redesigned front cover and inhalation effort control knob use co-molded components that provide the necessary grip, soft touch and ease of use. Available in several color kits
• Zirconium-plated inlet tube and heat sink for superior corrosion resistance.
• Redesigned heat sink dramatically increases surface area, aiding in the heat exchange necessary to avoid freeze-up.
• Co-molded silicone mouthpiece for better fit and less jaw fatigue
