Straightforward controls and reversible routing
The R105 combines a classic downstream valve with a VIVA switch. A metal valve housing and reversible hose attachment complete the listed arrangement.
A downstream octopus with reversible hose attachment
The Scubapro R105 Octopus uses a classic downstream valve and a metal valve housing. A yellow 39-inch / 1 m hose is part of the listed alternate configuration.
Who this suits
It is a candidate for a diver looking for a straightforward downstream alternate with a reversible hose arrangement. The source lists it as an unbalanced second stage and does not describe an adjustable breathing-effort knob. That gives you a concrete control and mechanism distinction when comparing it with an air-balanced adjustable model.
Hose and control layout
A dive/pre-dive VIVA switch provides the airflow setting. The reversible attachment allows an appropriate configuration to be planned for the setup, while the yellow hose identifies its alternate role. Follow the applicable Scubapro configuration instructions rather than treating reversibility as a reason to alter parts without them.
Mouthpiece and package scope
A Compact Hi-Flow mouthpiece is listed. The retailer’s broad fit language cannot establish comfort for every mouth, so consider the actual mouthpiece fit as part of the choice. This listing is the octopus rather than a first-and-second-stage regulator set.
What to compare
Match the R105 Octopus name and listed hose configuration when checking another offer. The downstream valve, metal housing and reversible hose design are its useful specification points, with the first-stage compatibility checked as part of the complete system.
