ABSTRACT:
A water depth measuring device for a fishing reel has a mounting seat integrally provided on an upper portion of a reel body. A main section of the measuring device is integrally formed and includes a watertight compartment housing electrical components such as a sensor, a controller, an indicator, a sound maker, and a power supply. A rotation detection section of the measuring device is provided in a projecting case mounted on the reel body and includes a roller mechanism having a magnet attached thereto. A roller included in the roller mechanism is biased into contact with a fishline wound on the fishing reel to rotate upon cast of the fishline from the fishing reel to cause rotation of the magnet and the generation of a flux signal. The sensor in the main section of the measuring device detects the flux signal and an indication of the length of the fishline cast is displayed on the indicator. The sound maker provides an audible signal indicating the cast of a selected length of fishline. The main section and rotation transmitting section are separately mounted on the reel body.
