• The octopus got its name due to the „pluralty of arms“ that is suggestive for the additional 2nd level. It is considered a backup for a buddy (diving partner) in trouble as two divers can get air from the same bottle.


  • See 2nd level.


  • Do ask for advice when buying the 2nd level. It is best to get an octopus from the same producer as the regulator. The octopus is, same as the 2nd level, being attached to the 1st level. Maybe you already have a jacket that has an inflator which can also function as a second regulator, an octopus is not needed in this case.


  • See regulator.
