Aqualung Legend Octopus

The Aqualung Legend Octopus is a pneumatically balanced second stage with a easily noticeable bright yellow purge cover, accent pieces and hose.

It is the ideal companion to the over-balanced Legend Series Regulators and the Titan LX.

This compact-sized alternate air source features a Diver-controlled Venturi Adjustment Switch (VAS), which prevents unwanted freeflow in the surface and provides maximum performance at depth.

The Octopus performs magnificently in cold water, due to the highly efficient heat exchanger surrounding the valve.

  • High-visibility yellow purge cover and accent pieces
  • 39” high-visibility yellow, Aqua Flex hose
  • Pneumatically-balanced to be ideally suited for a Legend over-balanced first stage
  • The venturi lever prevents unwanted freeflow when not in use
  • Excellent coldwater performance due to highly efficient heat exchanger surrounding the valve
