Your fish finder already tells you how deep the fish are... but how do you know how fast you should troll so that your lure rides at that depth? Wonder no longer! This handy calculator will recommend a speed based on information you provide. The advanced algorithm takes into account several variables which can affect the depth of your lure as you move across the water, including: - the type of line; some lines are more buoyant than others - the diameter of the line; thicker lines have more drag in the water, and will ride higher as speed increases - the amount of line you have in the water; longer lines allow for deeper trolling at higher speed - the weight of the lure; heavier lures sink further than lighter ones at a given speed Once you enter this information, and tell it how deep you want to fish, the app can estimate a trolling speed to allow you to fish at your desired depth. ## Key features - Trolling speed calculation - Considers line type and diameter - Accounts for line length in water - Integrates lure weight - Estimates speed for desired depth ## Recent user reviews (8 of 8) All indexed reviews: https://appshunter.io/ios/app/troll-speed/id985358812/reviews.md ### 1/5 — Not even close *2024-03-27* Give me a break! You say it takes 4.3mph to run a 1/4oz jig 10’ deep. Actual speed needed is about .8-1.0 mph. Yall can do better! ### 3/5 — Needs more *2020-06-07* Doesn’t have an option for lead core line. Also, it would be nice to set the speed and have it tell me the depth of my lure. ### 3/5 — Disappointed *2018-12-08* Braid line is not listed and the app is set up so as to yield only the trolling speed. I need trolling speed as an optional value in order to calculate the depth where the lure will ride. This app has potential so please keep revising. ### 1/5 — TrollingCalculator *2018-05-07* The app is not accurate not even close waste of money ### 1/5 — Troll speed *2016-05-23* Too restrictive with variables such as line type and it will only find the speed. You can't enter a speed and a depth and get length of line for example. I would return it if I could. I won't use it. ### 2/5 — Too limited *2015-05-04* Top lure weight is only 1oz. If you use 2 or 3oz like me this app doesn't help. Also, sometimes trolling speed needs to be the constant and line length the variable. Good concept but not very useful yet. ### 5/5 — Troll Speed *2015-04-26* A must have for all fishermen/women! Love it! Nothing in the app store like it! ### 5/5 — Trolling Speed *2015-04-23* Great app - works well ## Frequently asked questions about Troll Speed ### What is Troll Speed?
