Question & Answer
Why do some lures/devices show speed (MPH) and others do not have that designation?

Your question regarding trolling speed is a common one in regards to the Precision Trolling Data app. Trolling speed matters in regards to trolling depth with some lures and or devices and it doesn’t matter with others. For example, floating diving style crankbaits achieve the same depth at a wide variety of trolling speeds. In other words, a Flicker Shad No. 7 trolled at 1.5 MPH will dive to the same depth as the same lure trolled at 3.0 MPH. The reason for this is that while increasing trolling speed increases the pressure applied to the diving lip of the lure, increased speed also increases the amount of friction on the fishing line. The two forces cancel each other out and the end result is that floating/diving lures and devices achieve the same diving depths at a wide variety of speeds. This is why no speed is posted on the picker wheel on the app for these devices.
On the other hand, sinking devices such as keel sinkers, Tadpole Divers, Diving Planers, lead core line, Snap Weights, etc., are very much speed dependent. Our research has proven that even modest changes in speed can and does result in substantial differences in diving depth. In these cases, we typically test devices at a variety of different trolling speeds and post those speeds on the picker wheel in the app so anglers can choose the trolling speed that meets their needs. ...
