The Alpha 10 + CDX pairs Oceanic’s Alpha 10 second stage, which adds a real breathing-effort adjustment knob beyond the standard venturi switch, with the sealed, balanced cDX diaphragm first stage. It’s the cold-water-capable step up from the entry-level Alpha 8 Sport SP-5, aimed at divers who want sealed protection without moving to a full technical-tier regulator.
