ABSTRACT:
In a fishline length measurement device for a fishing reel, a random access memory is provided for storing as a data map a relationship between spool rotation numbers and corresponding fishline outer circumferential surface diameters, Both are detected during initial ,casts or winding of the fishline so that a outer circumferential surface diameter corresponding to a spool rotation number detected by a spool rotation sensor is selected from the data map in subsequent casts or winding of the fishline. Fishline length is calculated based on the detected rotation number and the selected diameter. Thus, it is possible to reduce consumptive electric power of the battery without any deterioration to the fishline length measurement function. In another feature of the present invention temperature compensation is provided to correct for changes in ambient temperature surrounding the fishing reel.
