The ScubaPro R105 Octopus is a dependable alternate air source built on a classic downstream second-stage design. As an octopus, its job is to be there when your buddy needs air, and the R105 keeps things simple and reliable, with a proven mechanism that breathes well when it counts.

It features a VIVA (Variable Inhalation Volume Adjustment) dive/pre-dive switch, which lets you reduce free-flow at the surface and then open up the airflow for easy breathing underwater. The hose attachment is reversible, so the octopus can be set up to suit either left or right routing on your rig.

Finished in the bright yellow that identifies an alternate air source, the R105 is easy for a buddy to spot in an out-of-air situation. For recreational divers in India looking for a solid, no-fuss octopus to complete their regulator setup, it is a sensible, hard-wearing pick.
