About this certified used regulators
The Poseidon Jetstream is a legendary, high-performance scuba regulator known for its unique servo-assisted valve and ambidextrous, side-exhaust design . It is widely used by commercial, technical, and scientific divers because of its outstanding cold-water reliability and extremely low inhalation effort. Servo-Assisted Valve: Operates like power steering in a car. A very light inhalation triggers the valve, allowing the regulator to automatically deliver immense airflow matching your exact breathing demand. Ambidextrous Design: The regulator hose can be routed over either the left or right shoulder without internal modifications. Side-Exhaust: Exhaled bubbles and water vent out from one side, which prevents water from easily entering the mouthpiece and keeps bubbles out of your direct line of sight.f Cold Water Readiness: Built with thermodynamics in mind, making it an excellent choice for icy and demanding environments 🤿 Certification & Inspection Report Date of Inspection: 7/16/26 Inspected By: Malibu Scuba Repair Parts to be Replaced: Complete Rebuild of 1st and 2nd.
