    Hello Hussain, yes we have the octo in-stock and we also have the matching regulator in-stock

  • tom:

    Bob  (Certified Scuba Instructor at


  • Jesse:

    How long is the hose that comes with it?

    Darrick  (Certified Scuba Instructor at

    Hello Jesse, the hose is 36" in length.

  • Traci:

    Im not the scuba diver, my 18 year old son is and I want to get him his own regulator for Christmas...this may be a stupid question but is that what this is?? It just seems extremely inexpensive compared to other ones I have looked at.

    This is only one part of what people think of when they discuss their "regulator". The reg, is actually the combined parts of a console, a regulator and the octo (or safe second). Also, if the person does not already own their BCD, they would need to add a Low Pressure Power Inflator Hose as well in order to use the regulator set up with a rental bcd.

Product Features

Fluid Dynamic Deflector: Receives and properly directs the airflow from the bypass tube to the mouthpiece.

Mesh Grid: Patented design which reduces the impact of water flow onto the second stage diaphragm, thus eliminating free flows even in strong currents.

Ultralight Techno Polymer: Abrasion resistant and affordable, ideal for diving in warm and moderate water temperatures.

Vortex Assisted Design: The air bypass tube conveys 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.

The air coming from the LP-hose passes through the second stage control valve and is conveyed directly to the mouthpiece through the by-pass tube (Mares patented). In the mouthpiece connector, the airflow creates a swirling action, or “vortex”. The core of the vortex is a low-pressure area, which, during inhalation, helps to hold down the second stage diaphragm, thus markedly increasing regulator sensitivity. The decisive advantage of the VAD System lies in the precision of its control. The VAD supplies the inhalation effort with just the intensity required.

Another advantage of the VAD system is related to the bypass tube, through which most of the air is delivered. In cold water diving, this system prevents ice crystals (which can be generated by the expansion of humid air in cold temperatures) from interfering with the proper operation of second stage components.
