The approach
Start with the right question.
Change speed, line length and lure depth one variable at a time.
In practice
Make it useful on the water.
Observe boat path and turns; the inside and outside lures may move differently.
Keep learning
Connect the dots.
Use this guide as a starting point, then compare it with the water you're fishing, the tackle you're using, and your own observations. Good fishing knowledge grows through real practice.
