With the Rozemeijer Pike Float with Light you always have light in the darkness! And it is precisely in those dark moments that those cautious pike and zander are a little less careful about baiting. This float comes with a CR425 (non-rechargeable) battery. Unscrew the cap, remove the battery and insert the pin into the cap. The light will come on, and you can screw the cap back on. Completely waterproof, so you can present a baitfish even during the darkest moments. When the battery runs out, replace it with a CR425 or a LIR425, the latter being rechargeable through a USB charger.
