ABSTRACT:
A swivel head counter for accurately measuring line in tension, such as a downrigger line passing over a pulley and the pulley driving a compact gear train. The gear train drives a counter wheel or knob so that actual depth or extension of downrigger line or the like may be directly read out. A swivel adjusts to maintain proper positioning of line to pulley.
