Fathom CCR Oxygen Needle Valve MAV

This is an oxygen needle valve MAV made by Fathom Dive Systems, maker of the Fathom CCR units.  This unit retails for nearly $600.  It was used in conjunction with a sidewinder CCR and has been used for roughly 100 hours of dive time.  There are scratches to the Delrin body but they are purely cosmetic and do not effect performance.  It's small and compact and fits int he palm of your hand.
