Night fishing works at all times of the year. To get in on the action, simply lower the Quarrow Submersible COB Green LED Fishing Light into the water in the area you plan to fish; its automatic sensor turns the light on when you submerge it, and turns it off again when you take it out of the water. In minutes youll see the food chain begin to ramp up, as baitfish are drawn to feed in the bright green glow. Soon after, the game fish follow, then the fun begins!
