The fishing information contained in the popular publication Precision Trolling is a troller’s dream come true. Dubbed “the Troller’s Bible” by the tens of thousands of anglers who use this information to target fish at specific depths, Precision Trolling is just what the name implies. Precision Trolling is a method of fishing that allows anglers to accurately predict the running depths of their favorite lures and diving devices!
By manipulating lead length anglers can easily “aim” their favorite fishing lures at specific depths, accurately target fish they are seeing on their sonar while avoiding costly snagged lures. Even better, once a productive lead length is determined, it’s easy to duplicate that lure and lead length combination with other lines, putting more lures in the strike zone!
The Precision Trolling Data App goes a step further. Once an angler has determined that a particular lure and lead length are effective at catching fish, it’s easy to search for other lures in the list of Precision Trolling App that achieve similar depths. Once a productive depth is determined where fish are biting, it’s a logical step to try different lures at the same depth to determine which lure or lures fish react best to.
The new Precision Trolling Data App allows anglers to access a wealth of trolling data. The familiar “Dive Curves” made popular in the Precision Trolling book are now incorporated into easy to use “pickers” or “wheels”. The Data Wheels let you adjust the “feet down” to determine the “feet back”. This is particularly useful if you want to target fish at a certain depth that you are seeing on your sonar unit. The Data Wheel also allows anglers to adjust the “feet back” to determine the “feet down” that the lure will dive. This a fast and effective way of zeroing in on a target depth with any of the lures or diving devices included in the Precision Trolling app.

Up your fishing game

I have been and am using “The Trollers Bible” from Precision Trolling (out of print) for years and sprang for the lifetime subscription. The data on the Offshore Guppy Weights andTadpoles is great. The segmented lead core information is invaluable. (More information is available on the website.) I like being able to update the data as new becomes available.
The one thing that I REALLY, REALLY miss from the print version is being able to compare my unmarked lure with the photo so that I know the data is spot on. Just guessing lure size makes the data is useless. The length of the lure would be a most valuable addition.
Landscape mode on the iPad please.
Overall a good app that will only get better. Worth the $$ if you are serious about trolling.

Incomplete But No Alternative

I am a bit upset that the lifetime purchase doesn’t even include all the crankbaits that I have in my precision trolling 7th edition book (more than a dozen are missing including ones I use). I mean why is that? How hard can it be to update the data in the app with the information you have already collected?

Unfortunately for the consumer, this is the only game in town for this sort of information due to some ridiculously broad and vague patent that should never have been granted. It was granted for “marine electronics with lure depth analyzer” what a joke!! Perhaps one day it will be challenged and tossed out so that this app will improve in order to compete in an open market.

Because of this lack of competition, precision trolling can get away with a limited line diameters and crankbaits offerings (covered brands are focused mostly on those that sponsor their fishing show).

All this being said, when you need information for a crankbait/ line combination already in the app, it does a great job. I just wish they would add crankbaits more often and with different lines. 10,15,20 The ability to see the dive curves as well as the scroll wheels would be nice for those of us used to the books and curve stickers.

Edit: Crashes have been fixed with recent app update. Still waiting on data from old book to be added and longing for the day this laughable patent gets tossed.

You really don't have any idea what your talking about, lets just leave it at that.

Great Info, But...

Purchased lifetime sub, takes a lot of the guesswork out of lure selection, resulting in more fish in the boat and greater confidence choosing lures and playing with colors or other variables instead of wondering if I'm really targeting the correct depth. A minor gripe is the line choice selection is very limited on most lures. Personally, I'd like to see more information using leadcore to put to rest heresy on how deep leadcore "really" dives using different lures and amount of line out. All-in-all, I'm extremely pleased regardless of the initial cost and feel the app to be highly beneficial in maximizing EFFECTIVE time on the water. Now add more LC data PT!!!!...and keep up the good work!
