Master Octopus

The Cressi Master Octo is built to the same standard as the Master Pro - because in an emergency, your buddy's regulator needs to perform as well as yours.

The housing is made from a premium medical-grade plastic that inhibits bacterial growth caused by saliva and moisture inside the regulator. The material is also highly resistant to saltwater degradation, so the surfaces remain smooth and easy to clean.

The elliptical design fits naturally against the face, and the large-surface elliptical diaphragm reduces the effort required to inhale, which is particularly useful at depth or in high-demand situations.

An internal heat exchanger uses the diver's breath to prevent ice from forming inside the regulator, making this the ideal cold-water companion.

An octopus that free-flows during a dive wastes vital air and disturbs marine life, so the Master Octo has two features that work together to prevent that from happening.

The first is a stainless-steel insert on the front cover, with carefully positioned ports that neutralise dynamic water pressure and eliminate current-induced free flow.

The second is an adjustable Venturi that prevents free-flows at the surface in pre-dive mode, maximises airflow in dive mode, and can be set to any position in between, so whoever is using it can focus on getting back to the surface safely.

• Cold Water Certified EN 250 A < 10°C
• Incredibly hygienic, with a medical-grade plastic housing that inhibits bacterial growth inside the Octo caused by saliva and moisture
• EU and FDA food-safe approved materials that won't leach toxins, even after years of use
• Highly resistant to saltwater degradation, so the surfaces stay smooth and easy to clean
• Elliptical design fits comfortably below the nose
• Large surface area elliptical diaphragm reduces inhalation effort, particularly at depth or in high-demand situations
• Internal heat exchanger uses warmth from the diver's breath to prevent ice forming inside the Octo
• Stainless-steel insert on the front cover neutralises dynamic water pressure and eliminates current-induced free-flow
• Adjustable Venturi maximises airflow in dive mode, prevents free-flows at the surface in pre-dive mode, and can be set to any position between the two
