Travis writes: I have just purchased the lifetime version of your precision trolling app. I was under the impression that along with all of the crankbaits listed that there would be more line diameter options as well as line types. Also, different options for trolling speed. I'm not sure what speed you based the data provided is. For the most part this should be a good investment, just wondering if any of the info I'm asking for is or will be provided. Thank you.

Your purchase of the Precision Trolling Data app is indeed a good investment. Literally hundreds of lures and trolling devices have been tested and the respective diving depths documented by our team using scuba diving methods to test, confirm and document every data point.
