PROBLEM TO BE SOLVED: To solve a problem of insufficient visibility of a considered method in which differential floats are constituted of two floats, an angler compares both the actions of the differential float 2 sinking and floating only by wave shaking and the differential float 1 sinking and floating by both a fish bite and wave shaking by visual observation, information of wave shaking is removed and only bite information is extracted. SOLUTION: The method for improving visibility of differential float is characterized by that the differential floats comprise the differential float 2 sinking and floating only by wave shaking and the differential float 1 sinking and floating by both a fish bite and wave shaking among the differential floats constituted of two floats, a fitting attachment and an information concentration mark and an angler watches the movement of the information concentration mark so that most importantly the angler obtains only the bite information, from which the information of wave shaking is removed, by visual observation.
