Egress means way out, exit, escape - the perfect description for an ideal octopus. The Apeks Egress has been designed as a left and right hand second stage regulator perfect for octopus use and emergency buddy breathing situations. It is, however, also entirely suitable as a left and right handed primary second stage compatible with any Apeks first stage. If used with an unsealed first stage then it is only recommended for warm waters, but is suitable for cold water diving when used with any Apeks environmentally sealed first stage.
