Abstract: A cordless, rechargeable, fish scaler assembly is provided. The scaler has a substantially cylindrical main body with a handle portion and a scaler portion. The scaler portion includes a scale guard which is rigidly connected to the handle portion and a plurality of longitudinally extending blades supported by a shall which is rotatably connected to the handle portion. The blades are partially enclosed within a cylindrical housing which operates to create a hollow space about the shaft thereby enhancing buoyancy of the scaler. The handle portion contains a rechargeable battery pack and also has a hollow portion to enhance buoyancy. The assembly includes at least two types of battery charging systems.
