You never know what could happen underwater. In the event of an air-related emergency, you'll be glad to have a spare second stage regulator (or scuba Octopus) with you. Your Octopus regulator functions as a reliable back-up air source should you or your dive buddy's primary second stage dive regulator malfunction. As an alternative air source, your scuba Octopus is made up of a back-up air source and air delivery system. The typical single-hose regulator comes equipped with a spare demand valve designed for emergency use by the diver’s buddy.

Scuba diving regulators and safety Octopus equipment are designed to help you breathe underwater. The Scuba Doctor carries scuba diving Octopus equipment from the top brands.
