The Onyx regulator outperforms many, much more expensive regulators with outstanding reputations - why? Among many reasons, two stand out:
The internal structure allows direct airflow through the 1st stage, providing lower turbulence for outstanding performance. Zeagle’s conical precision high-pressure valve provides much greater reliability and service life compared to conventional designs, while improving responsiveness and performance at all breathing rates. The braided LP hose provides high flow and tremendous abrasion resistance while having great flexibility. The compact exhaust tee, advanced black satin chrome finish and light weight construction give the Onyx a beautiful presence.
Work of breathing at heavy* demand: 0.95 Joule/Liter *198 (60M) depth, 750 psi inlet, 62.5 RMV (liters per minute respiratory volume)
Like all Zeagle regulators, The Onyx comes factory ready for use with EAN/ NITROX to 40% O2.
