This creation is a kind of buoyage,It includes have a floating seat,One set what float seat battery case,One luminescence component and an inductive component with humistor,The battery case can provide battery setting,Between the luminescence component sandwiched what battery case and inductive component,And the group place of connecing of the inductive component and luminescence component is equipped with waterproof washer,Wherein,When the buoyage senses fish news and submerges in water,Humistor is soaked in water,Resistance value is set to become smaller and current lead-through,Luminescence component is allowed to shine,Just what identification fish interrogates and night is suitable for fish,And can realizing self disassembling replacement,It is not easy to seep water again.本創作係一種浮標裝置，其包含有一浮座、一設於浮座的電池盒、一發光組件及一具有濕敏電阻的感應組件，該電池盒可提供電池設置，該發光組件夾設於該電池盒與感應組件之間，且該感應組件與發光組件的組接處設有防水墊圈，其中，該浮標裝置感應到魚訊而沒入水中時，濕敏電阻被水浸濕，使電阻值變小而電流導通，讓發光組件發光，便於辨識魚訊而適用於夜釣，且可自行拆卸替換，又不易滲水。
