The new H2Odyssey integrated air system with first and second stage regulator and 6-c.u.ft-pony is a great option for a redundant air system. The conventional second stage provides easy breathing performance and the integrated swivel makes it very comfortable to use. Larger air volume.
The H2Odyssey is a great air intergrated system to have. It is easy to fill and compact. It gives me piece of mind to know that I have a redundant air system for self rescue.
