The Paranologies Pendulox acts as a divinatory visual tool during your Paranormal Investigation. The Pendulox can be used in total darkness, perfect for ghost hunting. The custom quartz crystal in the pendulum has a UV light that illuminates the writing board. When the pendulum swings, it leaves its path with the glow in the dark UV light. The pendulum is attached to the tower but can be lifted off by hand. Works off of 4 AA batteries.
