• Heavy-duty octopus for demanding dives • Nickel and chrome-plated brass case • Perfect match with All Metal regulator line
The front cover with metal insert and Mesh Grid, combined with the new hose protector for better heat exchange, grants maximum dependability in the most demanding water conditions. Product Details Code: 416504 Material: Metal Second stage weight (g): 427 Nitrox: Yes
All Metal Technology: Outstanding mechanical resistance 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 the dry mouth feeling during the dive.
Mesh Grid: Patented design which reduces the impact of water flow onto the second stage diaphragm, thus eliminating free flows even in strong currents.
Superflex Hose: Extreme light weight and exceptional softness guarantee the maximum freedom of movement.
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.
