Use the Uv Light for charging up glow in the dark beads. Only takes a few seconds to charge the bead.
Note: change out the key ring with stronger one since the one it comes with is weak. We recommend ordering the flexible lanyard with key ring located in terminal tackle and accessories to help keep it secure.
UV light is also good for checking beads to see which ones are uv. Uv beads are good for murky / stained water.
