What an amazing regulator! I tried it during a 30m dive and the results were fantastic!
Kaitlyn Wong –
Would it be more practical if it’s compatible with DIN valves as well?
Junhao Lo –
Thank you for your suggestion, Kaitlyn! We’re currently looking into expanding our compatibility options, and DIN valves are definitely on our radar. Unfortunately, at this time, our Poseidon Cyklon 5000 Fixed Yoke Regulator is specifically designed to work with Yoke valves, but we’re working towards finding ways to make it more adaptable.

What are the compatible tank sizes?

Thank you for your question, Rohit. The Poseidon Cyklon 5000 Regulator is compatible with a wide range of tank sizes. It can accommodate most standard SCUBA cylinders, including DIN and Yoke. Specifically, it can handle tanks with a diameter range of 34mm to 48mm. However, for the most comfortable performance, we recommend using a tank between 11-15L. Please consult your local dive shop or our manual for more detailed specifications.

Would you say this regulator is suitable for cold water diving?
Junhao Lo –
Hello Emily, thank you for your question about the Poseidon Cyklon 5000 Fixed Yoke Regulator. While it’s a highly-rated regulator for its performance, we would need to refer to the product’s technical specifications to determine its suitability for cold water diving. The regulator’s design, including its materials and functionality, should be able to handle the cold water conditions, but we advise consulting the manufacturer’s guidelines for specific recommendations.
Kirsten Chen –
Overall, it’s an excellent choice for those looking for a reliable and easy-to-use regulator. Highly recommended!
Derrick Koh –
How does it prevent free-flowing during the dive?
Imran Hanafiah –
Thank you for sharing your concerns about the Poseidon Cyklon 5000 Fixed Yoke Regulator. The fixed yoke second stage regulator is designed to prevent a free-flow condition in case of a hose separation. This is achieved by a spring-loaded, pneumatically-actuated lever which, when a hose is disconnected, immediately closes the outlet end of the demand valve, thereby preventing the free flow of air.
