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
