Trolling Angles
Read full descriptionHide 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.

> TROLLLOGIC BRINGS FISHING INTELLIGENCE If you troll, you know how quickly things can change. Change a lure or color. Speed up. Slow down. Let out more line. Change depth. Then a rod fires - and sometimes it turns into pure chaos. TrollLogic remembers which lures were on, the line-out for each rod, and what was working so you can get everything set back up. It recognizes what's working during the trip and saves it for the next time you're on the water. > START EVERY TRIP WITH A PLAN TrollLogic combines what worked on your previous trips with today's fishing conditions - moon phase, barometric pressure, water clarity and water temperature - to give you immediate startup lure and speed suggestions. Start fishing with setups that worked before instead of guessing - or trying to remember which lures and speeds worked best the last time you were here. > SET THE CORRECT LURE DEPTH You can't catch fish if your lure isn't where the fish are. TrollLogic's Depth vs. Line-Out Calculator helps put your lure in front of or just above the fish. > SPOT REAL-TIME TROLLING PATTERNS As you log catches, TrollLogic looks for emerging patterns in speed, lure color, depth and line-out. When variables converge, TrollLogic identifies the fish-catching patterns developing in real time and alerts you. It even suggests setups for other rods so you can take advantage of what's working while the fish are biting. > TRACK EVERY CATCH AND WHERE IT HAPPENED Log each catch with its rod, lure, depth and fishing conditions. TrollLogic records the exact GPS location and your trail, showing what caught fish and exactly where it happened - so you can return to that spot. Whether trolling, reef fishing, casting for bass or tarpon, or ice fishing in the frozen north, TrollLogic remembers where you caught them. Every trip becomes part of your fishing history library - ready when you come back. > SEE THE BOTTOM CONTOURS YOU'RE FISHING TrollLogic includes detailed contour mapping for all the Great Lakes, supported coastal waters, and select inland lakes. We'll continue expanding mapping coverage as new areas become available. Use the maps with your live GPS position, trail and catch locations to see the bottom contours you're fishing, where you've been and where your fish were caught. > SHARE THE WHOLE TRIP Send another TrollLogic angler the whole trip - including catches, photos, trip details, GPS trail and waypoints. Instead of explaining what you were running or where the fish came from, just send them the trip. > NOT JUST FOR TROLLING Built around trolling, TrollLogic doesn't stop when the trolling rods come in. Casting, Spot/Anchor - including Ice Fishing - and River Drift modes let you record and remember those trips too.
