With the Rozemeijer Dart 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 cautious when feeding. 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 turn on, and you can screw the cap back on. Fully waterproof, this allows you to present a bait fish even during the darkest moments. There is also the option to replace the orange cap with a fluorescent green cap, which you can buy in sets of two. This allows you to mix and match if you are fishing with multiple floats or with multiple people. Thanks to the unique dart, you can let this float sail along with the wind and present your bait fish in places where that normally wouldn't be possible.
