ABSTRACT:
An annular gauge for determining the depth of a fishing lure on a fishing line angularly offset from vertical provides a chart displaying depth indicia. Each indicia accurately corresponds to a predetermined angular offset of the line. The indicia itself is positioned on the annular chart at an angularly offset location corresponding to the angle for which the indicia is accurate. As a result, when the gauge is properly aligned on the fishing rod, the approximately proper depth indicia is displayed at the top of the chart when the fishing rod is rotated by the offset angle.
