Zeagle Onyx II Octo

The adjustable features of a high-end primary, packed into a compact backup.

Your alternate air source should perform like your primary, and the Onyx II Octo does. It builds on the original Onyx, a regulator known for easy breathing, and adds an anodized aluminum heat sink for better cold-water performance. It's lightweight and low profile, it resists free-flow on the surface, and it breathes smoothly underwater. Its yellow accents and 36" braided hose make it easy for your buddy to find.

Features

• Pneumatically balanced downstream valve: Delivers smooth, easy airflow when you or your buddy need it.
• Adjustable inhalation resistance: A diver-controlled knob lets you set the cracking pressure to suit your preference or the conditions.
• Venturi lever: A dive/pre-dive control that stops free-flows on the surface and during entries.
• Anti-freezing heat sink: The anodized aluminum heat sink draws away cold and improves performance in chilly water.
• Ergonomic silicone mouthpiece: Reduces jaw fatigue.
• High visibility: Yellow cover and a 36" (91.4 cm) braided LP hose with 3/8" threads. The braided hose is flexible, high-flow, and highly abrasion-resistant.
• Compact and lightweight: Just 0.6 lbs (275 g) without the hose, with a low profile that fits cleanly into any setup.
• Durable, grippy build: Flexible and rigid thermoplastics, elastomeric polymer, and silicone rubber make it strong yet soft to the touch.
• Nitrox ready: Factory ready for EAN mixes up to 40%.

Materials: Thermoplastic cover and case, anodized aluminum heat sink, 316 stainless steel poppet seat insert with silicone overmold, elastomeric polymer diaphragm, elastomer exhaust valve, and silicone rubber mouthpiece.
