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. For more information on Precision Trolling and how to become a better troller click here: www.precisiontrollingdata.com Precision Trolling Data LLC owns a patent U.S. Patent No. 7,113,449 entitled “Marine Electronics With Lure Depth Analyzer” issued September 26, 2006 which prevents other companies/individuals from providing lure data on an electronic device.

Verdict

The call

The clearest difference is update cadence: Boat Speedometer at every 4 days against Precision Trolling's every 6 weeks.

On price, ads, in-app purchases and monetization model there is nothing between them.
