Did you know... Whilst some manufacturers market the Octopus as a cheaper product, a Poseidon Octopus is always of the same quality and materials as our regular second stages.


A number of features greatly improve safety and ease of use:

  • If debris has degraded the function of the exhalation check-valve, it can easily be reached and corrected by just twisting off the diffuser. It is the only part which needs to be disassembled, and if it gets lost during the operation, the regulator will continue to function but must only be used for immediate ascent.
  • In case of a malfunction in the 1st stage causing excessive intermediate pressure, the safety valve integrated in the1st stage will bleed off the excessive gas. This system both indicates to you that something is wrong so that you can take action, and because of the up-stream servo-valve technique, allows the regulator to continue to breath normally.(conventional downstream regulators are likely to free-flow in such a situation).
  • Integrated surgical hose fixing points safely secures the regulator to the diver, but in an emergency allows a distressed buddy to retrieve the regulator without undue stress to the diver.
  • The dead air space is low at just 49.5 ml (3 in3) making CO2 figures (hypercapnia) minimal. Inhalation resistance is incredibly low and unaffected by depth and breathing pattern.
  • Because of the unique Poseidon valve technology, there is no need for external adjustments.
  • Xstream is fitted with the new ergonomic mouthpiece Poseidon AIR, with asymmetrical lugs for the most comfortable bite.
  • All diaphragms are protected so that a strong current or using a scooter or tug does not affect either inhalation or exhalation.
  • A minimal number of moving parts, coupled with thermodynamic engineering, ensures the safe use in an extremely cold environment.
