What are the main differences between the Xstream Octopus and the Xstream primary regulator?
Imran Hanafiah –
Thank you for your question, Aloysius. The main differences between the Xstream Octopus and the Xstream primary regulator lie in their design, functionality, and purpose. While both offer exceptional performance and reliability, the Xstream Octopus is specifically designed as a secondary air source to be used in case of an emergency or as a backup regulator. The Xstream primary regulator, on the other hand, is designed for normal dive use. Key differences include the length of the hose, the compact design of the Octopus, and the fact that the primary regulator offers a range of configurations to fit individual diver needs. If you have any further questions, please don’t hesitate to ask.
