"Night fishing works at all times of the year. To get in on the action, simply lower the NEBO Submerser 300 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 you'll 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! Submersible to 30', this compact NEBO light measures just 9-1/4""L and is designed to deliver many memorable outings, with its tough impact-resistant construction, nonslip grip, water activated on/off switch, and watertight rubber endcaps. COB green LEDs provide 300 lumens of steady 360 degree illumination; runs up to 4 hours on 3 AA batteries (included). Comes with 20' of nylon rope.
