"Night fishing works at all times of the year. To get in on the action, simply lower the NEBO Submerser 500 Rechargeable 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 9-5/8""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. Green COB LEDs provide 500 lumens of steady 360 illumination; runs up to 4 hours on one charge of its lithium Ion battery. Includes 20' of nylon rope and USB charging cable.
