Atomic Z3 Octo

Atomic Aquatics Z3 Octopus

A high-performance backup second stage built to match your Z3 regulator.

Your alternate air source should breathe as well as your primary, and the Z3 Octo does. It carries over the Z3's patented second-stage technology in a high-visibility yellow package. That makes it easy to spot and hand off to a buddy during an out-of-air situation.

Features

• High-visibility design: The yellow front cover and 36" (91 cm) yellow LP hose stand out during buddy checks and real air-sharing. The hose length gives both divers room to breathe comfortably during an ascent.
• Automatic Flow Control (AFC): Atomic's patented system manages the venturi effect automatically. This keeps breathing natural at depth and helps prevent free-flow while the octo is stowed.
• Rapid Adjustment Knob: A soft, overmolded knob lets you detune by hand for octo use or surf entries.
• Titanium Seat Saving Dynamic Orifice: Protects the seat in storage and keeps the factory tuning crisp.
• Pneumatically balanced poppet: Paired with a high-flow case and lever for easy breathing at every depth and tank pressure.
• Corrosion-resistant build: Zirconium-plated brass with titanium components.
• Elliptical exhaust valve: Cuts exhalation effort at depth.
• Full-face purge: The entire front cover works as the purge button.
• Comfort-fit mouthpiece: Dual-silicone construction with tear-resistant bite tabs.
• Nitrox ready: Approved for non-dedicated use with mixes up to 40%.

The Perfect Pair
Match it with the Atomic Z3 Regulator for a complete, matched Atomic setup. You get the same smooth breathing and low-maintenance durability on both your primary and your backup.
