Trolling Angles

Read full description

The Trolling Angles app provides an economical, accurate, rapid, convenient, and versatile process and means with which a trolling angler can know how to present any trolled lure or bait at the desired depth where fish are most likely to perceive and strike the lure or bait. In a calibration phase, the angler uses the app to measure and record the angle of incidence between the water surface and the actual rigged trolling line, at multiple different line lengths. In an analysis phase, the app calculates a curve data structure which approximates the actual curved trolling line profile. In a trolling phase, after calibration and analysis, the angler specifies the desired depth, and the app uses the curve data structure to look up and display the line length which is required to troll at that depth. The patented method used by the Trolling Angles app does not rely on knowing the values of variable physical factors such as weight, line diameter, or lure geometry, or the mathematics of the physics which depends on those factors. It does not rely on external data for specific lure types. It does not rely on observing and measuring the submerged lure. Trolling Angles relies only on the line lengths and angles of the line as it enters the water surface, observed with the tackle and conditions in actual use. All configuration input data consisting of line lengths and angles, is generated, stored, and owned by the user on the local device. The free download of Trolling Angles is inactive. Features are activated by buying a subscription or license.
