• When the ONYX first came out, it earned high marks as an easy-breathing reg. Now Zeagle added a heat sink to the second stage, creating the ONYX II cold-water regulator.

    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 II comes factory ready for use with EAN/NITROX up to 40% O2.

    PLEASE NOTE: the regulator shown in the picture is the ONYX II 2nd stage. The OCTOPUS comes with more neon yellow accents!
