|Second stage weight (g):||269g||269g||269g|
Mesh GridPatented design which reduces the impact of water flow onto the second stage diaphragm, thus eliminating free flows even in strong currents.
All Metal TechnologyOutstanding 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 DesignThe 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.
