The Ultra Adj Octopus is constructed from a new ultra-lightweight and ultra-resistant technopolymer. The Vortex Assisted Design (VAD) enables unimpeded airflow and constant natural breathing at any depth. The innovative Twin Power System offers further adjustment, allowing the diver to control the speed of airflow. A simple twist increases airflow when required; designed for the hard working diver or very deep diver. The Octopus Ultra Adj is pneumatically balanced with the PAD (Pneumatic Assisted Design) system that offers comfortable and effortless breathing in every situation. The combination of the PAD and Twin Power systems coupled with the ability to adjust the breathing effort provides the best performance with maximum comfort in all conditions at any depth. A Superflex hose links the first stage to the second stage and provides support and flexibility for comfortable diving.
