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.
That stated we test our floating/diving crankbaits at about 2.0 to 2.5 MPH which is an average trolling speed. We also maintain that trolling speed throughout the entire testing process.
Trolling speed does however play a major role when dealing with sinking or negatively buoyant devices like lead core line, snap weights, keel sinkers, Tadpole Divers, etc. In the case of these devices we post the trolling speed right on the app and we use GPS technology to accurately maintain a trolling speed throughout the entire testing process. Also, in many cases we test at multiple trolling speeds to provide the maximum amount of trolling data.
As for line diameter options, the vast majority of our devices are tested on at least two line types and diameters such as .013 monofilament and 10/4 Fireline. Others are tested on line types or diameters ideal for using these respective devices. For example, the diving planers are typically tested on a 30# test super braid. It’s also important to note that
.013 monofilament is about the same diameter as most 40# test super braids, further giving anglers line options in which to fish without compromise to our depth data.
It might help you to also know that years ago we did a line conversion chart for our Precision Trolling books. That chart confused more people than it helped because the fishing tackle industry had and still has no standards for line diameter to break strength ratios. In effect, a line conversion chart would be little more than “ball parking” the diving depth and here at Precision Trolling Data we strive to provide the most accurate data possible.
I can tell you that for every line diameter you go up or down, the amount of influence on the maximum diving depth of a typical lure is less than two feet. In other words if you fish 12# test instead of the .013 10# we test on you are only losing about two feet of diving depth when the lure is fished on the longest practical lead lengths. In other words, line diameter isn’t the most profound variable influencing the diving depth of lures. Actually lead length is the big factor in determining diving depths of lures and that is precisely why we pay exceptionally close attention to managing our lead lengths on everything we test for Precision Trolling Data.
Thanks again for purchasing the Precision Trolling Data app and I hope I answered your questions.
