When you need a safe second you tend to need it quickly, so you better be able to see it, and it better be ready to deliver some air. The R105 Octo does that and much more. The R105 Octo is a modern second stage design that combines a classic downstream valve with a large diaphragm, functional purge button and VIVA switch for smooth and easy breathing and simple operation. Its robust construction, smooth air delivery and reliability makes the R105 Octo a sensible safe second stage for all divers and a perfect choice for deco tanks thanks to its extra-long high visibility hose and reversible hose attachment.
