Abstract
A fishing reel having a rotatable spool for winding thereon a fishing line, a Hall-effect sensor for detecting the spool rotation, and a microcomputer including an up/down counter for receiving signals from the sensor to count the number of spool revolutions during paying out and winding up of the fishing line. Calculation is provided by the microcomputer for determining the lengths of the paid out portion and the wound up portion of the fishing line with there being a display unit for displaying the calculated lengths. A memory associated with the microcomputer provides for selection from one of a plurality of formulas for calculation of line lengths corresponding to various line diameters. A control is provided for resetting the displayed value to 0 when the line is completely wound up.
