The F8 is Zeagle's flagship regulator: an environmentally sealed diaphragm first stage with a dry-sealed spring chamber, paired with a matching second stage. Zeagle developed it with Atomic Aquatics and counts more than 20 improvements over its earlier design.

Main features

• Dry-sealed spring chamber in the first stage to stop freezing in water colder than 40 °F.
• Conical precision high-pressure valve for reliability, service life and responsiveness at all breathing rates.
• First stage finished in flat black chrome plating to protect the brass from corrosion, with black PVD on the port plugs.
• Second stage with an inhalation effort control knob and a co-moulded silicone mouthpiece for fit and less jaw fatigue.
• Heat sink with greater surface area to dissipate cold, and a zirconium-plated inlet tube for corrosion resistance.
• Exhaust valve designed for dryness and lower exhalation effort; patented seat-saving orifice.
• Can be personalized with an F8 colour kit, sold separately.
• Made in the USA.
