The JB Fire Float is a premium balsa wood weighted float that has a fiber optic stem and a transparent bulb at the top. It is powered by a 3v lithium battery (included) that lights up the stem and bulb for greater visibility. It is available it two stem lengths; two and ten inches. The two inch version is great for open water applications, while the 10 inch functions as a fish house float as well as open water. The float features a line slot to allow an angler to easily change the float without cutting the line. Great for anglers working the night shift!
