Regulator – R105 Octopus

The SCUBAPRO R105 Octopus is a dependable backup second stage regulator designed to deliver consistent airflow and peace of mind in out-of-air situations. Built around a proven downstream valve design, the R105 emphasizes simplicity, reliability, and durability—making it an excellent choice for recreational divers who value straightforward performance and safety.

Its rugged metal valve housing increases long-term reliability while helping dissipate cold during airflow, contributing to stable breathing performance. The dive/pre-dive VIVA switch helps reduce unwanted freeflows at the surface and ensures smooth, controlled air delivery once underwater.

For maximum safety and visibility, the R105 comes equipped with a high-visibility yellow super-flow hose, making it instantly recognizable in emergency situations. The 39-inch (1 m) hose length offers flexible routing and comfortable sharing, while the reversible hose attachment allows the octopus to be easily configured for standard setups, pony bottles, or decompression tanks.
