Zeagle Onyx II Octo

The Zeagle Onyx II Octo is a lightweight, compact scuba regulator octopus designed to integrate with standard diving gear. Built on the DNA of the original Onyx Octo, this unit offers adjustable inhalation resistance, free-flow control, and anti-freezing features for reliable performance in diverse diving conditions.

Construction uses durable materials chosen for scuba gear: TPU cover, Nylon 12 case, a poppet seat with a 316 stainless steel insert and silicone overmold, nitrile O-rings, elastomeric polymer diaphragm, and a silicone exhaust valve. The 36-inch hose (91.4 cm) features 3/8-inch threads for compatibility with common regulator setups.

Key benefits include a pneumatically balanced downstream valve for smooth airflow, a venturi lever that enables precise free-flow control, and an ergonomic silicone mouthpiece designed to reduce jaw fatigue. The overall design remains low profile and compact, with an anti-freezing heat sink integrated to support performance in cooler water.
