This bundle pairs a Zeagle first and second stage regulator with the Zeagle Onyx II Octo, giving you a complete regulator setup with a backup second stage ready to go. At checkout, choose which regulator you’d like paired with the octopus: the Zeagle Onyx II, the Envoy/RaZor II, or the F8.
The Zeagle Onyx II 1st stage uses a balanced design for consistent performance, with five LP ports and two HP ports for routing hoses however your setup calls for. It’s environmentally sealed with a Dry Environmental Seal and Hydro Transmitter for added durability, includes a braided hose, and carries a 1-year service interval. The Onyx II 2nd stage pairs a downstream valve with a balanced diaphragm for smooth airflow, along with Dive/Pre-Dive Venturi Control and diver-adjustable breathing sensitivity so you can fine-tune the regulator to your preference, all in a compact, anodized aluminum housing.
The Zeagle Onyx II Octo rounds out the set as your backup second stage. It shares the same pneumatically balanced downstream valve and venturi lever for precise free-flow control, and adds an ergonomic silicone mouthpiece to reduce jaw fatigue during longer dives. The second stage housing is built from a TPU cover and Nylon 12 case, with a 316 stainless steel poppet seat insert, nitrile O-rings, an elastomeric polymer diaphragm, and a silicone exhaust valve, and it comes on a 36-inch (91.4 cm) hose with 3/8-inch threads for compatibility with standard regulator setups.
