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.

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!

Won't go trolling without it!!

I have this app on my I pad and iPhone. I had the trolling bible before this and it was great. This was the next logical step due to all the new updates that can come at any time. There are so many new companies and new baits from current companies that come thru how else would you keep up. Anyone that trolls must use this app. It is much more accurate than what is printed on the package or downloaded from other sources. Nobody does it better. Thank you precision trolling, you saved me so much work. TJ Kremer, Lake City PA

The trolling bible for every one

Kr is ace

I have two editions of the trolling bible. The first one the pages would stick together when they got wet. The second was vastly improved when they coated them in a plastic. This app is an improvement on that. When purchased as a lifetime edition you should get all the updates. Really looking forward to that. My fishing buddy and I love to crank fish and this kind of information is invaluable. Thanks precision trolling people, you are appreciated...
