The float has a metal reinforced eyelet to prevent potential breakages. Attached to your mainline via a snap link swivel it can be used as standard in daylight conditions, but during low light or night time situations simply unscrew the top to operate the internal bright LED indicator switch. The Greys LED Nite Float comes fitted with a CR2540 lithium battery and also includes a spare, giving you up to 400 hours of life! It has an internal O ring giving a perfect watertight seal and cocks perfectly without adding any extra weight. If you wish to target night feeding fish, or simply want to mark your swim after darkness has fallen, you need look no further.
