Mares Octopus Fusion

The Octopus Fusion is robust and reliable. The body is forged from brass; chromium-plated and finished with a 'pearl' surface. It features high thermal conductivity properties that make it ideal for use in very cold water.
The Vortex Assisted Design (VAD) allows unimpeded airflow and constant natural breathing at any depth. The innovative Twin Power System offers further adjustment by allowing the diver to control the speed of airflow. A simple twist increases airflow when required.

The Ultra second stage is pneumatically balanced with the PAD (Pneumatic Assisted Design) system, offering comfortable and effortless breathing in every situation.

The combination of the PAD and Twin Power systems, combined with the ability to adjust the breathing effort provides the best performance with maximum comfort in all conditions at all depths.

A Superflex hose links the first stage to the second stage and provides support and flexibility for comfortable diving.

All Metal Technology
Outstanding mechanical reliability and high thermal conductivity make our metal 2nd stages extremely long lasting and ideal for cold water dives. The high thermal conductivity of metal reduces also the dry mouth feeling during the dive.

VAD - Vortex Assisted Design
The air bypass tube delivers air to the mouthpiece creating a swirling vortex with a low pressure area in the center that keeps the diaphragm down during inhalation, for very sensitive and easy breathing at all depths.

Superflex Hose
Extreme light weight and exceptional softness guarantee the maximum freedom of movement.

Twin Power
New, flow control manages the delivery rate of your gas, from natural breathing to power breathing. The former is the traditional way of breathing a Mares regulator, (VAD) while the latter (VAD+) provides an extra push when you need it.
