The OmniSwivel Gas Switch Block allows a diver to change between two separate air tanks
without having to remove their full face mask.  The knob turns a full 180 degrees ensuring that
there is no accidental switching during the dive.  The knob pointing to the first position(as shown
in top photo) signifies that the air source closest to the outlet is in use.  

The center photo shows the GSB in the shut-off position.  In case of a second stage failure, a
diver can turn the flow off to mask and switch to an alternative regulator.  This shut-off position
also prevents a cross blending of gases during a switch over.

The bottom photo shows the GSB using the secondary air source.
