An Adjustable Trolling Device, or dodger, consisting of a flat primary body and configured to be removably attached at one or more points along its edge to a primary fishing line, and at other points on its edge, at least some of which may be substantially opposite to the point where it is affixed to the primary fishing line, to trailing fishing bait, or lures. The device has an attached mounting surface, rotatable through 360.degree., or a specified range, projecting one or more guiding fins, substantially perpendicular to the rotatable mounting surface. The mounting surface, by its nature, may be rotated to place the guiding fins at alternate desired angles from the leading fishing line, so that movement of the dodger through the water may produce a variety of rotation or roll characteristics of the dodger and, correspondingly, the trailing bait or lures.
