Unlike many lighted nighttime floats with tangle-prone appendages the Thill Nite Brite is a true center-slider float that glows brighter lasts longer and makes fishing in the dark easy and productive. As a true slip-float however the Nite Brite also functions as a great float for daytime use too. Simply unscrew the cap push on the battery top and replace the cap. The E.L. battery/light gives off a super-bright glow that's easy to see even in waves.
