The Jasu Led spotlight is your assistant when you need maximum attention from predators. The Led Spotlight reacts to the water and starts flashing, creating an attraction in dark water. The light is excellent for spotting in deep or dark water. The light attracts fish from perch to small fry.We recommend using the light especially with different types of tippets and puddles, as well as with vertical spots. The light is easily and effortlessly attached to the lure with a quick-release fastener.The battery lasts for about 50 hours of fishing.
