Zeagle RKO Octo Inflator
The Octo+ is the simplest and least complicated alternate air source. It combines the functions of an alternate air system and a BC power inflator in a single unit, thereby eliminating one hose from your diving system. Includes the Power Inflator hose for attachment to your regulator first stage (Does not include the Corregated Hose which is already on your BC). This can be installed on any BC with a standard size inflator hose.
