500 Hour Flashing Marker

The 500 hour flashing marker is small and compact, fits on the back of a dive tank without getting in the way.  Is visible in low vis or on night dives.  No more remembering to purchase glow sticks, no more batteries to replace.  Simply wrap it around your tank valve and go.  It activates upon getting wet and stop flashing when the contacts dry.
