One is better than two.
The Oceanic Air XS 2 Inflator Octo
combines the performance and reliability of an octopus and a power inflator into a low-profile, streamlined package. The breathing performance is superior to that of many conventional octopus regulators. The Oceanic Air XS 2 Inflator Octo
may be purchased separately, or pre-installed on your Oceanic Buoyancy Compensator.
