This Scubapro duo changes that approach by providing dedicated, rugged housing for your most sensitive instrumentation.

After weeks of use in varying depths, the Cressi Octopus XS-Compact has proven itself as a reliable piece of Italian-made kit. While it shares the same sturdy casing as the standard Compact, the high-visibility yellow cover and extended 100 cm hose make it much easier to locate during a buddy breathing emergency. The engineering here is clever. It utilizes a Venturi effect flow deviator and an injection system to channel pilot air directly to the mouthpiece. This setup provides extremely high performance, though you will notice the inhalation effort is calibrated to be slightly more substantial than the base model. It is a lightweight, flexible, and highly functional secondary regulator that prioritizes visibility and consistent airflow when you need it most.
