The approach
Start with the right question.
Explore edges, vegetation, wood, shade and nearby depth as possible fish-holding habitat.
In practice
Make it useful on the water.
Change retrieve style and presentation angle before assigning a success to lure color alone.
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.
